Description

Technical Field

[0001] The present application relates to the technical field of cutting systems, and in particular to a sawing machine. Background Art

[0002] At present, in the forklift manufacturing industry, in order to improve production efficiency and product quality, the forklift industry has put forward higher requirements for the processing accuracy of forklift accessories. Especially in the cutting process of forklift handrails, it is necessary to cut the inclined surface of the steel pipe bent at both ends. The unprocessed handrail is a hollow pipe with a longer middle part and shorter parts bent downward on both sides. The two ends of the handrail are the planes of the circular pipe. In actual operation, the two side planes need to be polished into a bevel, which is welded to the plane of one side of the connector.

[0003] Fixed sawing machines are generally used to grind bevels. Traditional fixed sawing machines are used to fix the mechanism of the armrests, and cannot fine-tune the processing inclination angle according to the machine conditions. This is not conducive to processing products with qualified inclined cutting surfaces, resulting in a high scrap rate. Summary of the invention

[0004] In view of the fact that traditional fixed sawing machines cannot fine-tune the processing inclination angle according to the machine conditions due to their fixed structure, which is not conducive to processing products with qualified inclined cutting surfaces, resulting in a high scrap rate, the present application proposes a sawing machine that is convenient for cutting the inclined surface of the handrail.

[0005] A sawing machine comprises a workbench, a cutting mechanism, a translation mechanism, a base, a support plate, a front support mechanism, a rear support mechanism and a pressing mechanism.

[0006] The cutting mechanism and the translation mechanism are both mounted on the workbench. The base is mounted on the translation mechanism. The support plate is hinged to the base and can be fixed to each other.

[0007] The height-adjustable front support mechanism supports the front side of the support plate. The height-adjustable rear support mechanism supports the rear side of the support plate.

[0008] The inclined upper surface of the support plate has a work station for clamping the two ends of the workpiece from the bottom and the side; the clamping mechanism is used to clamp the upper surface of the workpiece installed on the work station; the translation mechanism is used to drive the base to translate so that the two ends of the workpiece are respectively moved to the bottom of the cutting mechanism; the cutting mechanism is used to cut the end of the workpiece below.

[0009] By adopting the above technical scheme, the support plate is hinged to the base, and the front and rear sides of the support plate are supported by the front support mechanism and the rear support mechanism respectively, and the height of the front support mechanism and the rear support mechanism are adjustable, and the fastening member is detachable, so that the hinge angle of the support plate and the base can be fine-tuned, and the angle can be fixed again, that is, the inclination of the support plate is fixed, thereby locking the inclination of the workpiece again. Since each batch of workpieces has slight differences, the sawing machine of this structure is conducive to fine-tuning the inclination angle of the processing surface for different batches of workpieces and different machine conditions, and can better process workpieces with the cutting surface inclination meeting the requirements, thereby reducing the scrap rate.

[0010] A preferred structure of the sawing machine is that the sawing machine further includes a first movable block, a second movable block, a third movable block and a fourth movable block.

[0011] The support plate has a linear slide groove, and the first movable block, the second movable block, the third movable block and the fourth movable block can slide along the slide groove in an adaptive manner. The workpiece is a rod with two ends bent. The opposite surfaces of the first movable block and the second movable block are parallel inclined surfaces, so that the first movable block and the second movable block can adapt to clamp one bent end of the workpiece, and the opposite surfaces of the third movable block and the fourth movable block are parallel inclined surfaces, so that the third movable block and the fourth movable block can adapt to clamp the other bent end of the workpiece. The first movable block, the second movable block, the third movable block and the fourth movable block are respectively fixed in the slide groove by locking members. The heights of the first movable block, the second movable block, the third movable block and the fourth movable block on the support plate are all lower than the workpiece.

[0012] By adopting the above technical solution, four movable blocks are used to clamp the two ends of the workpiece to be processed. The position of the movable blocks can be adjusted and then locked. The clamping mechanism can be pressed on the two ends of the workpiece without interference to clamp the workpiece adaptively and improve the yield of cutting the bevels at both ends of the workpiece.

[0013] A preferred structure of the sawing machine is that the clamping mechanism includes a clamping block and a first axial driver. The first axial driver is installed on the bottom surface of the support plate, and the clamping block is located above the support plate. The bottom surface of the clamping block is parallel to the upper surface of the support plate. The output shaft of the first axial driver passes through the support plate and is fixed to the clamping block. The output shaft of the first axial driver is perpendicular to the lower surface of the clamping block. The first axial driver can drive the clamping block to clamp the upper surface of the workpiece.

[0014] By adopting the above technical solution, the clamping block and the support plate are adapted to fit the upper and lower surfaces of the workpiece from the upper and lower sides respectively, which has a good clamping effect on the workpiece, the workpiece is not easy to slide during the processing, and the yield rate is high.

[0015] A preferred structure of the sawing machine is that the pressing block is a wedge-shaped block. The pressing block is tilted with its tip facing downward. The first axial driver is connected to the upper end of the pressing block. The tip of the pressing block faces the gap between the first movable block and the second movable block below, and faces the gap between the third movable block and the fourth movable block below.

[0016] The clamping mechanism further includes two guide rods, which are arranged on both sides of the output shaft of the first axial drive and are parallel to the output shaft of the first axial drive, and connect the support plate and the clamping block.

[0017] By adopting the above technical solution, the first axial driver is connected to the thicker upper end of the clamping block, the lower end of the clamping block is light, the downward pulling force on the first axial driver is small, the output shaft of the first axial driver is not easy to deform, and the structure is stable. With the support of the guide rod, the clamping block can be stably driven axially, improving the stability of the clamped workpiece and improving the yield rate.

[0018] A preferred structure of the sawing machine is that the sawing machine also includes two groups of rear pressure mechanisms, which are respectively arranged on both sides of the output shaft of the first axial drive; each group of the rear pressure mechanisms includes a second axial drive and a rear pressure block; the second axial drive includes a stator and an output shaft; the stator of the second axial drive is installed on the support plate and is located outside the movable range of the clamping block; the output shaft of the second axial drive is parallel to the upper surface of the support plate, and the output shaft of the second axial drive is connected to the rear pressure block; the second axial drive can drive the rear pressure block to press against the rear side of the workpiece.

[0019] By adopting the above technical solution, after the first axial driver drives the clamping block to press on the upper surface of the workpiece, the two second axial drivers each drive a rear clamping block to press against the back of the workpiece, making the position of the workpiece more stable and not easy to cause deviation when cutting the two ends of the workpiece.

[0020] A preferred structure of the sawing machine is that the front support mechanism includes two groups of support components, which are respectively supported on both sides of the front end of the support plate. The rear support mechanism includes two groups of support components, which are respectively supported on both sides of the rear end of the support plate.

[0021] Each group of the support components includes a lower screw and an upper screw sleeve. The upper screw sleeve is threadedly connected to the upper end of the lower screw. The upper screw sleeve has a planar upper surface. The front bottom edge of the support plate is a circular arc bottom angle edge with a cross section of a quarter arc; the upper surfaces of the two upper screw sleeves of the front support mechanism respectively support the two ends of the circular arc bottom angle edge.

[0022] By adopting the above technical solution, the lower screw and the upper screw sleeve can rotate relative to each other to adjust the height of the support assembly. The upper surface of the upper screw sleeve is a plane with a large support area, and can be adapted to the support plate with a fine-tuned tilt angle, thereby playing a stable supporting role. After the support plate rotates, the arc bottom angle edge of the front end can be tangentially supported by the upper surface of the upper screw sleeve, and the support plate and the upper screw sleeve are not easy to wear. With the support of the rear end and the hinged structure of the support plate to the base, the support plate is not easy to slip on the upper screw sleeve.

[0023] A preferred structure of the sawing machine is that the sawing machine further comprises two cylindrical blocks, which are respectively fixed to the bottom surface of the support plate, the axis of each cylindrical block is in a horizontal position, and the axes of the two cylindrical blocks are in the same straight line or parallel to each other. The upper surfaces of the two upper screw sleeves of the rear support mechanism respectively support the side curved surfaces of the two cylindrical blocks.

[0024] By adopting the above technical solution, after the support plate is rotated at an angle, the cylindrical block can still be adapted to be tightly pressed against the rear support mechanism, and the support is linear support. Compared with some point support relationships, this support relationship has a large support area and good support stability. Combined with the support at the front end and the hinged structure of the support plate to the base, the support plate is not easy to slip on the upper screw sleeve.

[0025] A preferred structure of the sawing machine is that both ends of the support plate are hinged to the base, and the hinge structure includes an inner cylinder, an outer ring and a clamping bolt. The inner cylinder is integrally formed with the base. The outer ring is integrally formed with the support plate. The outer ring is fitted around the outer circumference of the inner cylinder. The outer ring is provided with a screw hole. The clamping bolt can be screwed into the screw hole to clamp the inner cylinder.

[0026] By adopting the above technical solution, the tightening bolt can be unscrewed to release the hinge rotation restriction of the support plate to the base, so that the support plate can rotate, and then the tightening bolt is tightened to restrict the hinge rotation of the support plate and the base.

[0027] A preferred structure of the sawing machine is that the translation mechanism includes a third axial drive, a track and a displacement sensor. The third axial drive is connected to the base, the base is mounted on the track, and the third axial drive can drive the base to move back and forth along the track. The displacement sensor is configured to sense the driving distance of the third axial drive.

[0028] By adopting the above technical solution, the translation mechanism can accurately adjust the position of the base, so that the workpiece on the base is accurately positioned and cut accurately.

[0029] A preferred structure of the sawing machine is that the cutting mechanism includes a lifter, a mounting member, a motor, a speed reducer, a cutting fluid reservoir, a pump, a nozzle and a saw blade. The lifter is mounted on the workbench. The mounting member is fixed to the output shaft of the lifter. The motor is mounted on the mounting member, and the speed reducer, the cutting fluid reservoir and the pump are all mounted in the mounting member. The motor is connected to the speed reducer. The speed reducer is connected to the saw blade. The pump is connected to the cutting fluid reservoir and the nozzle. The nozzle faces the saw blade. The translation mechanism can drive the two ends of the workpiece to be successively under the saw blade.

[0030] By adopting the above technical solution, the cutting mechanism raises and lowers the saw blade to the workpiece or away from the workpiece, and drives the saw blade to rotate to cut the workpiece. During cutting, cutting fluid can also be sprayed to improve cutting efficiency and reduce processing temperature.

[0031] In summary, the sawing machine of the present application has the following beneficial effects: the support plate is hinged to the base, and the front and rear sides of the support plate are supported by the front support mechanism and the rear support mechanism respectively, and the height of the front support mechanism and the rear support mechanism are adjustable, and the fastening member is detachable, so the hinge angle of the support plate and the base can be fine-tuned, and the angle can be fixed again, that is, the inclination of the support plate is fixed, thereby locking the inclination of the workpiece again. Since each batch of workpieces has slight differences, the sawing machine of this structure is conducive to fine-tuning the inclination angle of the processing surface for different batches of workpieces and different machine conditions, and can better process workpieces with the inclination of the cutting surface meeting the requirements, thereby reducing the scrap rate. The workpiece is an armrest. By using this sawing machine, the speed and accuracy of cutting the armrest are improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0042] The technical solutions in the embodiments will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the following embodiments, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0043] refer to Figure 1 A sawing machine includes a workbench 1, a cutting mechanism 2, a translation mechanism 3, a base 4, a support plate 5, a front support mechanism 6, a rear support mechanism 7 and a clamping mechanism 8.

[0044] The sawing machine is used to cut the two ends of the workpiece 9, which is a steel pipe with both ends bent into obtuse angles. The sawing machine is used to cut the inclined ends at the bent sections at both ends of the workpiece 9 so that the two end inclined surfaces can be fitted to the car body and welded and fixed to use as handrails.

[0045] In the sawing machine, the cutting mechanism 2 and the translation mechanism 3 are both installed on the workbench 1. The base 4 is installed on the translation mechanism 3. The support plate 5 is hinged to the base 4, and the relative rotation of the hinged structure is limited by a detachable abutment member, so that the upper surface of the support plate 5 is an inclined surface for loading the workpiece 9, and the clamping mechanism 8 then clamps the workpiece 9, drives the translation mechanism 3 to the bottom of the cutting mechanism 2, and then the cutting mechanism 2 can cut one end of the workpiece 9 first, and move the translation mechanism 3 again, so that the cutting mechanism 2 can cut the other end of the workpiece 9, thereby cutting out a steel pipe with inclined surfaces at both ends.

[0046] The structure in which the above support plate 5 is hinged to the base 4 can be specifically that both ends of the support plate 5 are hinged to the base 4, the hinged structure includes an inner cylinder 401 and an outer ring 503, and the fastening member is a fastening bolt 504. The outer ring 503 is adaptively sleeved on the outer circumference of the inner cylinder 401. The inner cylinder 401 is integrally formed with the base 4. The outer ring 503 is integrally formed with the support plate 5. The outer ring 503 is provided with a screw hole. The fastening bolt 504 can be adaptively screwed into the screw hole to fasten the inner cylinder 401. Unscrewing out the fastening bolt 504 can release the hinged rotation restriction of the support plate 5 on the base 4, so that the support plate 5 can rotate, and then tightening the fastening bolt 504, so that the hinge of the support plate 5 and the base 4 is restricted from rotating.

[0047] If the relative rotation of the hinged structure of the support plate 5 and the base 4 is limited only by the detachable abutting member, the limiting effect is poor. When cutting the workpiece 9, the support plate 5 is subjected to a large force and is easy to shake forward and backward. Therefore, the sawing machine is also provided with a front support mechanism 6 and a rear support mechanism 7 which are installed together on the base 4 and supported on the front and rear sides of the support plate 5 respectively. The front support mechanism 6 and the rear support mechanism 7 can be moved to the cutting position together with the base 4. When the workpiece 9 is cut, both the front and rear sides are supported and it is not easy to rotate forward and backward relative to the base 4, thereby maintaining the stability of the cutting result.

[0048] In order to make the sawing machine adapt to the different bevel angle requirements at both ends of the workpiece 9, since the support plate 5 can be rotated relative to the base 4 and fixed by the fastening parts, the front support mechanism 6 and the rear support mechanism 7 should also be height-adjustable. When the inclination angle of the support plate 5 relative to the base 4 changes, the front support mechanism 6 and the rear support mechanism 7 can also adaptively adjust their respective heights to provide adaptive support for the front and rear sides of the support plate 5.

[0049] refer to Figure 2 The workpiece 9 is a rod with two ends bent, which is a product of bending the two ends of a straight steel pipe. Both bent ends are inclined outward, and the two bent sections and the middle section are on the same plane. The two ends of the straight steel pipe are beveled to serve as the handrails of the forklift, and the beveled surface is welded on the forklift frame.

[0050] refer to Figure 3The support plate 5 has a station suitable for installing the workpiece 9, so that the workpiece 9 installed on the station is in an inclined state. The clamping mechanism 8 is used to clamp the workpiece 9 installed on the station. The translation mechanism 3 is used to drive the base 4 to translate, so that the two ends of the workpiece 9 are respectively moved to the bottom of the cutting mechanism 2. The cutting mechanism 2 cuts the end positions of the two bent sections of the workpiece 9 to cut out the inclined surface.

[0051] In the sawing machine based on the above structure, the support plate 5 is hinged to the base 4, and the front and rear sides of the support plate 5 are supported by the front support mechanism 6 and the rear support mechanism 7 respectively, and the height of the front support mechanism 6 and the rear support mechanism 7 are adjustable, and the fastening parts are detachable, so that the hinge angle of the support plate 5 and the base 4 can be fine-tuned, and the angle can be fixed again, that is, the inclination of the support plate 5 is fixed, thereby locking the inclination of the workpiece 9 again. Since each batch of workpieces 9 has slight differences, the sawing machine of this structure is conducive to fine-tuning the inclination angle of the processing surface for different batches of workpieces 9 and different machine conditions, and can better process the workpiece 9 with the cutting surface inclination meeting the requirements, thereby reducing the scrap rate.

[0052] refer to Figure 4 In order to clamp the workpiece 9, the sawing machine is provided with a first movable block 10, a second movable block 11, a third movable block 12 and a fourth movable block 13.

[0053] The support plate 5 has a linear slide groove, and the first movable block 10, the second movable block 11, the third movable block 12 and the fourth movable block 13 slide along the slide groove in an adaptive manner. The opposing surfaces of the first movable block 10 and the second movable block 11 are parallel inclined surfaces, and the first movable block 10 and the second movable block 11 can adaptively clamp a bent section of the workpiece 9. The opposing surfaces of the third movable block 12 and the fourth movable block 13 are parallel inclined surfaces, and the third movable block 12 and the fourth movable block 13 can adaptively clamp another bent section of the workpiece 9. The first movable block 10, the second movable block 11, the third movable block 12 and the fourth movable block 13 are respectively fixed in the slide groove by locking members, and the locking members can be screws. The height of the first movable block 10, the second movable block 11, the third movable block 12 and the fourth movable block 13 exposed from the upper surface of the support plate 5 is lower than the diameter of the workpiece 9. The gap between the first movable block 10 and the second movable block 11, the gap between the third movable block 12 and the fourth movable block 13, and a part of the upper surface of the support plate 5 constitute a work station, and both gaps are inclined grooves with opposite inclination directions, which are used to accommodate the two ends of the workpiece 9. When the workpiece 9 is placed on the support plate 5, one end is embedded in the gap between the first movable block 10 and the second movable block 11, and the other end is embedded in the gap between the third movable block 12 and the fourth movable block 13. The clamping mechanism 8 can press on the workpiece 9 in a direction parallel to the upper surface of the support plate 5 without interference, so that the workpiece 9 is better fixed before cutting.

[0054] The sawing machine uses four movable blocks to clamp the two ends of the workpiece 9 to be processed. The positions of the four movable blocks can be adjusted and then locked. The two ends of different batches of workpieces 9 can be clamped adaptively to improve the processing yield.

[0055] refer to Figure 5 For this sawing machine, the clamping mechanism 8 may include a clamping block 801, a first axial driver 802 and two guide rods 803. The first axial driver 802 may be an oil cylinder. The first axial driver 802 is mounted on the bottom surface of the support plate 5, and the clamping block 801 is located above the support plate 5. The bottom surface of the clamping block 801 is parallel to the upper surface of the support plate 5. The output shaft of the first axial driver 802 vertically passes through the support plate 5 and is vertically fixed to the lower surface of the clamping block 801. In this sawing machine, the support plate 5 may be a flat plate. The two guide rods 803 are arranged on both sides of the output shaft of the first axial driver 802 and are parallel to the output shaft of the first axial driver 802. The two guide rods 803 connect the support plate 5 and the clamping block 801, thereby stably guiding the back and forth linear movement of the clamping block 801.

[0056] The upper surface of the support plate 5 includes a gap between the first movable block 10 and the second movable block 11, and a gap between the third movable block 12 and the fourth movable block 13, which can be adapted to fit the bottom surface of the workpiece 9. Driven by the first axial driver 802, the clamping block 801 is pressed on the upper surface of the workpiece 9. The clamping block 801 and the support plate 5 are adapted to fit the upper and lower surfaces of the workpiece 9 from the upper and lower sides respectively. The first movable block 10 and the second movable block 11 wrap one end of the workpiece 9 laterally, and the third movable block 12 and the fourth movable block 13 only wrap the other end of the workpiece 9 from the side. The overall clamping effect on the workpiece 9 is good, and the workpiece 9 is not easy to slide or warp during the processing, etc., with less processing rework and high yield.

[0057] refer to Figure 6 In order to maintain the stability of the first axial driver 802 driving the clamping block 801 to move back and forth axially for a long time, one embodiment designs the clamping block 801 to be wedge-shaped, that is, the position close to the output shaft of the first axial driver 802 is thick, and the position away from the output shaft of the first axial driver 802 is thin to form a pointed end. The clamping block 801 is tilted and the pointed end faces downward. The first axial driver 802 is connected to the upper end of the clamping block 801. The pointed end of the clamping block 801 faces the gap between the first movable block 10 and the second movable block 11 below, and faces the gap between the third movable block 12 and the fourth movable block 13 below, so that the clamping block 801 can press the two ends of the workpiece 9 and clamp the workpiece 9 to facilitate processing.

[0058] The first axial driver 802 is connected to the thicker upper end of the clamping block 801. The lower end of the clamping block 801 is light, and the downward pulling force on the first axial driver 802 is small. The output shaft of the first axial driver 802 is not easy to deform, and the structure is stable. With the support of the guide rod 803, the clamping block 801 can be stably driven axially, which improves the stability of the clamped workpiece 9 and improves the yield rate.

[0059] When cutting the workpiece 9, the two ends of the workpiece 9 have been limited by the first movable block 10 and the second movable block 11, and the third movable block 12 and the fourth movable block 13, respectively, and are also limited by the clamping block 801, but there is still space for the two ends of the workpiece 9 to retreat, so the middle section of the workpiece 9 needs to be limited on the rear side.

[0060] Since the front side of the middle section of the workpiece 9 is limited by gravity against the second movable block 11 and the third movable block 12, the upper and lower surfaces of the middle section of the workpiece 9 are also limited by the clamping block 801 and the support plate 5, so its cutting stability is good. However, in order to further enhance the position stability of the workpiece 9 during cutting, it is also necessary to limit the rear side of the middle section of the workpiece 9. The following is a rear side limiting solution. The sawing machine also includes two sets of rear pressure mechanisms, which are respectively arranged on both sides of the output shaft of the first axial drive 802. Figure 7 , each group of rear pressure mechanism includes a second axial driver 14 and a rear pressure block 15. The second axial driver 14 includes a stator and an output shaft. The stator of the second axial driver 14 is mounted on the support plate 5 and is located outside the movable range of the clamping block 801. The output shaft of the second axial driver 14 is parallel to the upper surface of the support plate 5, and the end of the output shaft of the second axial driver 14 is connected to the rear pressure block 15. The output shaft of the second axial driver 14 is perpendicular to the output shaft of the first axial driver 802. The second axial driver 14 can drive the rear pressure block 15 to press against the rear side of the workpiece 9. The height of the rear pressure block 15 should be smaller than the gap width between the clamping block 801 and the support plate 5 when it is pressed on the upper surface of the workpiece 9. As Figure 8 The side of the rear pressing block 15 that abuts against the workpiece 9 is an arc surface, and in other embodiments it can also be a plane, both of which can tightly abut against the rear side surface of the workpiece 9.

[0061] The tightening sequence can be: first, the first axial driver 802 drives the clamping block 801 to press on the upper surface of the workpiece 9, and then the two second axial drivers 14 each drive a rear clamping block 15 to insert into the gap between the clamping block 801 and the support plate 5, and press against the rear side surface of the workpiece 9. Then, the four sides of the middle section of the workpiece 9 are limited, the position is more stable, and the workpiece 9 is less likely to shift when being cut at both ends, and basically no defective products are produced.

[0062] The front support mechanism 6 includes two groups of identical support components, which are respectively supported at the two ends of the front side of the support plate 5. The rear support mechanism 7 includes two groups of identical support components, which are respectively supported at the rear position of the lower surface of the support plate 5.

[0063] refer to Fig. 9 The structures of the four groups of support assemblies are basically the same, and each group of support assemblies includes a lower screw rod 601 and an upper screw sleeve 602. The upper screw sleeve 602 is threadedly connected to the upper end of the lower screw rod 601. The upper screw sleeve 602 has a planar upper surface for supporting the support plate 5.

[0064] In the above structure, the lower screw rod 601 and the upper screw sleeve 602 can rotate relative to each other to adjust the height of the support assembly. The upper surface of the upper screw sleeve 602 is flat, has a large supporting area, and can be adapted to the support plate 5 for fine-tuning the tilt angle, thereby playing a stable supporting role.

[0065] In order to better support the front end of the support plate 5 before and after the rotation, the front side lower side of the design support plate 5 is a circular arc bottom angle edge 501. The cross section of the circular arc bottom angle edge 501 is a quarter arc. The upper surfaces of the two upper screw sleeves 602 of the front support mechanism 6 support the two ends of the circular arc bottom angle edge 501 respectively. Then after the support plate 5 rotates, the circular arc bottom angle edge 501 of the front end can be supported by the upper surface of the upper screw sleeve 602 tangentially, and the support is a linear support, and the support stability is good, and the support plate 5 and the upper screw sleeve 602 are not easy to damage, and the service life is long, and the support of the rear end and the hinged structure of the support plate 5 to the base 4 make the support plate 5 not easy to slide on the upper screw sleeve 602. If the front side lower side of the support plate 5 is a right angle side, the support plate 5 and the upper screw sleeve 602 are easy to wear and tear, which brings constant to the adjustment angle.

[0066] In order to better dock and support the rear end of the support plate 5 before and after rotation, the sawing machine is designed to also include two cylindrical blocks 502, which are respectively fixed to the bottom surface of the support plate 5, and the axis of each cylindrical block 502 is in a horizontal position, and the axis of the two cylindrical blocks 502 are in the same straight line or parallel to each other. The upper surfaces of the two upper screw sleeves 602 of the rear support mechanism 7 respectively support the side curved surfaces of the two cylindrical blocks 502. After the support plate 5 rotates at an angle, the cylindrical block 502 can still fit tightly against the rear support mechanism 7, and the support stability after adjusting the angle is still good. With the support of the front end and the hinged structure of the support plate 5 to the base 4, the support plate 5 is not easy to slip on the upper screw sleeve 602.

[0067] The translation mechanism 3 of the sawing machine includes a third axial driver 301, a track 302 and a displacement sensor. The third axial driver 301 can be a cylinder. The output shaft of the third axial driver 301 is connected to the base 4, and the base 4 is installed on the track 302. The output shaft of the third axial driver 301 is parallel to the track 302, and the third axial driver 301 can drive the base 4 to move back and forth along the track 302. The displacement sensor is used to sense the driving distance of the third axial driver 301, so that the translation mechanism 3 can accurately adjust the position of the base 4, so that the position of the workpiece 9 installed on the base 4 is accurate, so that the two ends of the workpiece 9 are moved to the bottom of the cutting mechanism 2 in sequence, and the two ends of the workpiece are accurately cut into inclined surfaces.

[0068] For the sawing machine, the cutting mechanism 2 includes a lifter 201 , a mounting member 202 , a motor 203 , a reducer, a cutting fluid storage tank, a pump, a nozzle and a saw blade 204 .

[0069] The lifter 201 is mounted on the workbench 1. The mounting member 202 is fixed to the output shaft of the lifter 201. The motor 203 is mounted on the mounting member 202, and the reducer, the cutting fluid reservoir and the pump are all mounted in the mounting member 202. The motor 203 is connected to the reducer. The reducer is connected to the saw blade 204. The pump is connected to the cutting fluid reservoir and the nozzle, and the nozzle faces the saw blade 204. The translation mechanism 3 can drive the two ends of the workpiece 9 to be located under the saw blade 204 in sequence.

[0070] The cutting mechanism 2 raises and lowers the saw blade 204 to the workpiece 9 or away from the workpiece 9, and drives the saw blade 204 to rotate to cut the workpiece 9. During cutting, cutting fluid can also be sprayed to improve cutting efficiency and reduce processing temperature. A collection port 101 is provided on the workbench 1 for collecting waste cutting fluid.

[0071] The sawing machine of the above embodiment has an adjustable inclination angle of the support plate 5, that is, the cutting angle of the workpiece 9 can be adjusted to meet the needs of different products, or necessary adjustments can be made when an abnormal cutting angle is found during the processing to improve the yield. The sawing machine is provided with four movable blocks to clamp the two ends of the workpiece 9, and the position of the movable blocks can be adjusted according to the different lengths of the workpiece 9, so that workpieces 9 of various lengths can be processed. The sawing machine uses a clamping block 801 to clamp the workpiece 9 clamped by the four movable blocks, so that the position of the workpiece 9 is basically fixed when being cut, and it is not easy to shake, and the processing yield is high. The sawing machine is also equipped with two sets of rear pressure mechanisms to abut the rear side of the workpiece 9, so that the workpiece 9 has basically no space to shake backwards, which further improves the standardization of the size and appearance of the cut product and improves the product yield.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
