[0001] The utility model relates to the technical field of machine tool equipment, in particular to a machine tool for processing automobile air guide strips. Background Art

[0002] In the traditional processing of air guide strips, sawing and drilling are carried out in two steps, which requires the use of two machine tools. During the sawing and drilling process, positioning and installation are required twice. The disadvantages are that the development and manufacturing cost of the machine tool is high, the floor space is large, and the processing precision is low. For example, in patent CN202964005U, a machining device for clamping and producing aluminum tubes for luggage racks in one time includes a bed, a sawing machine, a sawing feed device, a drilling and reaming feed device, a lateral displacement device, and a pneumatic clamping fixture. The sawing machine is installed on the sawing feed device, the sawing feed device is installed on the bed, the drilling and reaming feed device is installed on the lateral displacement device, the lateral displacement device is installed on the bed, and the pneumatic clamping fixture is installed on the bed. This patent combines the sawing device and the drilling device on the same machine tool, but has problems such as loose clamping, slow processing efficiency, and low processing precision. Utility Model Content

[0003] In view of the problems of loose clamping, slow processing efficiency and low processing precision in the prior art, the utility model invents a processing machine tool that integrates sawing and drilling. The machine tool has a relatively simple structure, can be accurately positioned with only one clamping, has high control precision and high processing efficiency.

[0004] A machine tool for processing automobile air guide strips includes a base, a sawing mechanism and a drilling mechanism. Two groups of sawing mechanisms and two groups of drilling mechanisms are arranged on the base and can slide relative to the base. A clamping and positioning mechanism is arranged between each group of sawing mechanisms and drilling mechanisms. The clamping and positioning mechanism includes a side clamping and positioning mechanism, a lower clamping and positioning mechanism, and a support seat. Therefore, after clamping the workpiece, the utility model can perform sawing and drilling work at the same time, and only requires one clamping and positioning; the clamping device has a side clamping and positioning mechanism and a lower clamping and positioning mechanism, so that it can be clamped on the side and bottom surface to prevent the workpiece from being displaced during processing and affecting the processing accuracy; sawing and processing work are performed at the same time, which simplifies the processing procedure and improves the processing efficiency.

[0005] The side clamping and positioning mechanism includes a side clamping cylinder, a side clamping block and a second support block. The side clamping block is driven by the side clamping cylinder. The side clamping block and the second support block are clamped together and are both semi-suspended on the support seat, which is arranged on the base. Through the cooperation between the side clamping block and the second support block, the workpiece can be clamped on the side to prevent the workpiece from moving during processing, resulting in processing errors. The support seat plays a supporting and fixing role.

[0006] The lower clamping and positioning mechanism includes a lower clamping cylinder, a lower clamping block, a lower clamping cylinder fixing block, and a lower clamping block fixing block. The lower clamping cylinder drives the lower clamping block. The lower end of the lower clamping cylinder is fixed on the base, and the upper end is connected to the lower clamping cylinder fixing block. The lower clamping block fixing block is fixed on the lower clamping cylinder fixing block, and the lower clamping block fixing block is fixed to the lower clamping block. The side and bottom surfaces of the workpiece are clamped and fixed by the clamping block, which can avoid processing errors caused by the movement of the workpiece during sawing and drilling, thereby affecting the production quality of the workpiece. Fixing the workpiece can improve the processing accuracy and effectively improve the qualified product ratio of the workpiece. Side clamping and lower clamping can work simultaneously.

[0007] Preferably, the width of the second support block is adapted to the width of the groove of the lower clamping block fixing block; when clamping, the suspended bottom surface of the second support block contacts the top surface of the groove of the lower clamping block fixing block; the lower clamping block is located between the side clamping block and the second support block. The lower clamping block fixing block not only fixes the lower clamping block, but also limits the position of the side clamping block. The size of the side clamping block is adapted to the groove of the lower clamping block fixing block; when clamping, the suspended bottom surface of the side clamping block contacts the top surface of the groove of the lower clamping block fixing block, and the lower clamping cylinder stops moving upward, completing the lower clamping work. The lower clamping block is located between the side clamping block and the second support block, below the workpiece, and can be clamped in the vertical direction.

[0008] Preferably, the side clamping block and the second support block are designed with sawing grooves and through holes at the same position; the second support block is provided with a clamping groove; and the side clamping block is placed parallel to the second support block. The side clamping block and the second support block are provided with grooves for setting the sawing mechanism and through holes for the drilling mechanism. This structural design facilitates the processing of the workpiece and the positioning of the workpiece. The position of the sawing groove is just enough for the saw blade to pass through, and the position of the through hole is just enough for the drill bit to pass through. The diameter of the through hole is larger than the diameter of the drill bit, which can play a role in chip removal and prevent the workpiece, the drill bit and the side clamping block from being damaged at the same time due to deviations when positioning the workpiece, so as to facilitate positioning when clamping the workpiece. At the same time, the width of the sawing groove is also larger than the width of the saw blade, which can also play a role in chip removal and facilitate cleaning. The second support block is designed with a clamping groove, the size of which is adapted to the workpiece, and plays a role in clamping and positioning.

[0009] Preferably, the sawing mechanism includes a motor 1, on which a rotating shaft 1 is provided, and the rotating shaft 1 drives the saw blade to rotate; the drilling mechanism includes a motor 2, on which a rotating shaft 2 is provided, and a drill holder is provided on the rotating shaft 2, and a drill bit is clamped in the drill holder. The saw blade rotates around the rotating shaft 1, and the upper part is wrapped by a protective cover to protect the safety of the operator and avoid accidental touch and injury. The drill bit and the rotating shaft 2 are on the same horizontal line, and the horizontal line is parallel to the slide rail. As a result, the drilled hole is perpendicular to the tangent of the contact point on the workpiece surface, and such a hole will not have a dimensional deviation.

[0010] Preferably, the center lines of the drill holder and the drill are parallel to the rail assembly. When the drill holder and the drill are on the same horizontal line, inaccurate machining of the size of the mounting hole can be avoided, so that the diameter of the through hole is slightly larger than the diameter of the drill.

[0011] Preferably, the first rotating axis, the second rotating axis, the sawing groove, the center line of the through hole, and the slide rail assembly are all parallel. The end face of the workpiece and the mounting hole are parallel to each other; and are parallel to the long side of the base; to ensure that the processing angle is consistent.

[0012] As a preferred embodiment, the lower clamping block is fixed by the lower clamping block fixing block, and the lower clamping cylinder is used to promote the vertical movement of the workpiece. The clamping device limits the vertical movement of the workpiece, and plays a role in fixing and clamping.

[0013] Preferably, two sets of drilling mechanisms, sawing mechanisms and clamping and positioning mechanisms are arranged on the base, and they are arranged symmetrically. The symmetrical structure can ensure that the force on the base is relatively even, and there will be no deviation caused by excessive weight on one side, so that the processing position is not on the same horizontal line; the components used in the symmetrical structure are consistent and interchangeable, which improves interchangeability and makes it more convenient to replace parts.

[0014] Preferably, the drilling mechanism and the sawing mechanism are mounted on a movable bracket, the movable bracket is fixedly connected to a slider group, and the slider group is embedded in a slide rail group. The slider group is embedded in the slide rail group so that the slider group can only move in a horizontal line. The movement direction and movement path of the movable bracket are limited by the sliding of the slide rail group and the slider group, so that the sawing mechanism and the drilling mechanism placed on the translation bracket are processed in parallel paths.

[0015] Preferably, the drilling mechanism and the sawing mechanism are arranged on a mobile frame through a sliding mechanism, and the sliding mechanism includes a slide rail group, a slider group sliding on the slide rail group, and a mobile frame fixed to the slider group. The driving cylinder 1 and the driving cylinder 2 are fixed by the cylinder driving block 1 and the cylinder driving block 2, so that the mobile frame can avoid the situation that the sawing mechanism and the drilling mechanism cannot be moved to the original position due to the displacement of the cylinder. The mobile frame 1 and the mobile frame 2 are controlled by different cylinders respectively, so that drilling and sawing can be performed at the same time.

[0016] Preferably, the rail group includes rail group 1 and rail group 2 arranged in parallel with each other. The rail group 1 and rail group 2 arranged in parallel make the sawing direction parallel to the drilling direction, preventing the size of the mounting hole from being unable to be installed with bolts and other connecting parts due to the problem of drilling angle.

[0017] Compared with the prior art, the utility model performs one-time clamping through a clamping and positioning device, clamping and fixing the workpiece from the side and bottom respectively, making the clamping more secure and improving the processing accuracy; thus, sawing and drilling can be carried out simultaneously, effectively improving the processing efficiency; combining the sawing mechanism and the drilling mechanism also makes the structure of the utility model simpler.

[0026] Embodiment 1:

[0027] As the instruction manual Figure 1 , 2 As shown in Figures 3 and 4, a machine tool for processing automobile air guide strips includes a base 30, a sawing mechanism 31 and a drilling mechanism 32, characterized in that the sawing mechanism 31 and the drilling mechanism 32 are integrated on the base 30 and slide relative to the base 30; a clamping and positioning mechanism is arranged between the sawing mechanism 31 and the drilling mechanism 32; the clamping and positioning mechanism includes a side clamping and positioning mechanism 37, a lower clamping and positioning mechanism 38 and a support seat 25. The workpiece is clamped from the side and bottom by the clamping and positioning mechanism, which is carried out by the side clamping block and the lower clamping block, and can effectively play the role of clamping the workpiece. The sawing mechanism is located on the left side of the clamping and positioning mechanism, and the drilling mechanism is located on the right side of the clamping and positioning mechanism; during processing, the sawing mechanism works from left to right, and the drilling mechanism processes from right to left, and the side clamping block can ensure that the workpiece does not move in the horizontal direction, which affects the processing accuracy. The sawing mechanism and the drilling mechanism are both arranged on the base, and can slide relative to the base.

[0028] like Figure 5The side clamping and positioning mechanism 37 includes a side clamping cylinder 26, a side clamping block 24 and a support block 22. The side clamping block 24 is driven by the side clamping cylinder 26. The side clamping block 24 and the support block 22 are clamped together and are both semi-suspended on the support seat 25. The support seat 25 is set on the base. The lower clamping and positioning mechanism 38 includes a lower clamping cylinder 29, a lower clamping block 23, a lower clamping cylinder fixing block 28, and a lower clamping block fixing block 27. The lower clamping cylinder 29 drives the lower clamping block 23. The lower end of the lower clamping cylinder 29 is fixed on the base 30, and the upper end is connected to the lower clamping cylinder fixing block 28. The lower clamping block fixing block 27 is fixed on the lower clamping cylinder fixing block 28, and the lower clamping block fixing block 27 is fixed to the lower clamping block 23. The workpiece is placed in the gap between the supporting block 2 and the side clamping block and in the groove of the supporting block 1 to play a positioning role, and then the fixing effect is started through side clamping and lower clamping.

[0029] Support block 22 is adapted to the lower clamping block fixing block 27; when clamped, the suspended bottom surface of support block 22 contacts the top surface of the groove of the lower clamping block fixing block 27; the lower clamping block 23 is located between the side clamping block 24 and support block 22. Among them, the side clamping device and the lower clamping device are in a matching relationship. The groove width of the lower clamping block fixing block is exactly the width of support block 2, which plays a role in limiting the position of the side clamping block. When the lower clamping device is clamped, the top surface of the groove of the lower clamping block fixing block will contact the bottom surface of support block 2 to ensure the clamping of the lower clamping device. The lower clamping cylinder and the lower clamping cylinder fixing frame are both located on the lower side of the side clamping device.

[0030] The base 30 includes a bracket seat 1 and a lower bottom plate 2, which play a supporting and fixing role. The base is composed of a lower bracket seat and a lower bottom plate. The lower bottom plate is a horizontal platform, on which a horizontal slide rail group 33 and a slider group 34 are arranged, and the slider group is adapted to the slide rail group. The lower bracket seat is composed of brackets, which support the lower bottom plate. The long side of the lower bottom plate is supported by a larger number of brackets to improve the stability and structural strength of the device.

[0031] Since the processed component - the automobile air guide strip itself is a symmetrical structure, the processing device is also a symmetrical structure, and the sawing mechanism 31, the drilling mechanism 32, and the clamping and positioning mechanism are all placed symmetrically. Support block 1 21 is installed on the edge of the long side of the base 30, and there is also a groove slightly larger than the diameter of the automobile air guide strip in the middle, which is used to fix the automobile air guide strip, and the base and support block 1 are connected together by bolts. The clamping and positioning mechanism is located between the drilling mechanism and the sawing mechanism, and the support seat 25 is connected and fixed on the base. The side clamping block 24 and support block 2 22 are placed in the upper half of the support seat in suspension, and the side clamping block and support block 2 are placed in parallel, with the sawing groove relative to the sawing groove, and the through hole relative to the through hole. The side clamping block and support block 2 together can play the role of clamping the air guide strip. The lower clamping block is located at the lower part of the side clamping block and support block 2.

[0032] The support block 1 21 supports the long strip of the automobile air guide strip, and the side clamping block 24 and the lower clamping block 23 clamp the end of the air guide strip. The groove of the support block 1 is consistent with the clamping groove in the support block 2 22, so that the plane where the air guide strip is located is parallel to the lower bottom plate 2 on the base 30. The sawing direction is perpendicular to the plane where the air guide strip is located, and the drilling direction is also perpendicular to the end of the workpiece. The distance between the support block 1 and the support block 2 is appropriate, so that the air guide strip can remain stable when placed on the top.

[0033] The side clamping block 24 is provided with a sawing groove for the sawing mechanism 31 and a through hole for the drilling mechanism 32. This structural design facilitates the processing of the workpiece and the positioning of the workpiece. The position of the sawing groove is just right for the saw blade 14 to pass through, and the position of the through hole is just right for the drill bit 20 to pass through. The diameter of the through hole is larger than the diameter of the drill bit, which can play a role in chip removal and prevent the situation where the workpiece, the drill bit and the side clamping block are damaged at the same time due to deviation in the positioning of the air guide strip. At the same time, the width of the sawing groove is also larger than the width of the saw blade, which can also play a role in chip removal and facilitate cleaning.

[0034] The slide rail group is divided into a slide rail group 1 4 and a slide rail group 2 6, both of which are placed horizontally. The mobile frame 36 is composed of a mobile bracket 12 and a mobile bracket 2 17; they are controlled by a driving cylinder 1 9 and a driving cylinder 2 11 respectively; the driving cylinder 1 and the driving cylinder 2 are fixed in position by a cylinder driving block 1 8 and a cylinder driving block 2 10. The slide rail group 1 4 is embedded with an adapted slider group 1 3, and the slider group 1 is fixed with a mobile bracket 1; the slide rail group 2 6 is embedded with an adapted slider group 2 5, and the slider group 2 is fixed with a mobile bracket 2 17. A sawing mechanism 31 is arranged on the mobile bracket 1, and its horizontal movement on the slide rail group 1 is controlled by the driving cylinder 1; a drilling mechanism is arranged on the mobile bracket 2, and its horizontal movement on the slide rail group 2 is controlled by the driving cylinder 2.

[0035] Lubricating oil or grease can be added between the rail group 33 and the slider group 34, which can effectively reduce the sliding friction and effectively extend the service life of the mobile device. Reducing the sliding friction can also reduce the power provided by the cylinder and save energy.

[0036] The movable bracket 12 is provided with a motor 15 and a saw blade 14 from top to bottom, and a rotating shaft 13 is provided at the center of the saw blade, and the saw blade rotates around the rotating shaft 1. The saw blade is controlled to rotate by the motor 1.

[0037] The second movable bracket 17 is provided with a second motor 16, a second rotating shaft 18, a drill holder 19, and a drill 20. The second rotating shaft, the drill holder, and the drill are located on the same horizontal line, and the drill is controlled by the second motor. The second motor is installed above the above horizontal line. Being located on the same horizontal line can avoid the deviation of the angle when drilling, and avoid the situation where the mounting hole of the drill is not compatible with the connecting piece.

[0038] The mobile bracket 12 is located on the left side of the mobile bracket 2 17, and the slide rail group 1 4 is parallel to the slide rail group 2 6. The slider group 1 3 and the slider group 2 5 are both composed of four sliders of the same size, which are respectively connected at the right angles of the mobile bracket 1 and the mobile bracket 2, and the edges extend beyond the mobile bracket 1 and the mobile bracket 2 by a suitable distance. The connection position of the slider group and the mobile bracket is appropriate and symmetrical, so that the four sliders are evenly stressed, effectively avoiding the wear of a slider due to greater pressure, increasing the friction during sliding, and requiring the cylinder to apply greater force and easily generating noise.

[0039] As the instruction manual Figure 5 In the figure, there is a clamping and positioning mechanism for the product between the slide rail group 1 4 and the slide rail group 2 6, and the bottom of the clamping and positioning mechanism is directly fixed to the base 30. The clamping of the product is composed of a lower clamping cylinder 29, a lower clamping block cylinder fixing block 28, a lower clamping block fixing block 27, and a lower clamping block 23. The lower clamping block cylinder fixing block fixes the lower clamping cylinder; the lower clamping cylinder controls the movement of the lower clamping block to play a clamping role; the lower clamping block fixing block limits the movement direction of the lower clamping block to the vertical direction; the cylinder also enables this part to perform clamping work in the vertical direction. Similarly, the side clamping cylinder 26 controls the movement of the side clamping block 24. The side clamping cylinder and the side clamping block are located near the saw blade, and clamping the workpiece keeps the workpiece stable during the sawing process, ensuring the smoothness of the sawing cut and the accuracy of the workpiece size. The up and down and left and right movements of the workpiece are controlled by the lower clamping device and the side clamping device, so that the workpiece is fixed in one position, ensuring that the workpiece does not shift in position during the sawing and drilling process, and the clamping is more secure.

[0040] The working method of the utility model is: fix the utility model in a suitable position, and connect the motor and cylinder to the power supply and air source. After turning on the switch 7, put the product on the support block 1 21 and beside the support block 2 22, and the side clamping cylinder 26 and the lower clamping cylinder 29 drive the side clamping block 24 and the lower clamping block 23 respectively to clamp from the side and bottom to complete the clamping action. After completing the clamping action, the driving cylinder 1 9 drives the mobile bracket 12 to move in the direction of the product, that is, the internal direction of the device, and the motor 1 15 drives the saw blade 14 to complete the sawing work; at the same time, the driving cylinder 2 11 drives the mobile bracket 2 17, and the motor 2 16 drives the drill bit to move in the direction of the product to complete the drilling action; the symmetrical two parts of the device work simultaneously. After completing the above work, the driving cylinder 1 and the driving cylinder 2 drive the mobile bracket 1 and the mobile bracket 2 to reset, and the side clamping cylinder and the lower clamping cylinder are released to take out the product.

[0041] The lower clamping block 23 is fixed by the lower clamping block fixing block 27, and the lower clamping cylinder 29 promotes the vertical movement; the lower clamping cylinder is fixed to the base 30 by the lower clamping cylinder fixing block 28. Through the clamping and positioning mechanism, the vertical movement of the workpiece is limited, and the fixing and clamping effect is played.

[0042] The support block 1 21 is installed on the long side of the lower base 2 in the base 30, and has a groove in the middle. The width of the groove is slightly larger than the diameter of the air guide strip, and the air guide strip can be placed on the support block. The groove of the support block 1 and the clamping groove of the support block 2 are located on the same horizontal line. The horizontal line is parallel to the horizontal line formed by the drill bit 20 and the drill bit holder 19.

[0043] The switch 7 is arranged in the middle position of the present application, and the switch can control the opening and closing of the driving device.

[0044] From the above processing steps, it is reflected that the utility model simplifies the processing steps, combines the sawing and drilling steps, saves the production cost of the machine tool, reduces the floor space of the machine tool, speeds up the production efficiency, and improves the precision of workpiece processing.

[0045] Embodiment 2:

[0046] To process different workpieces, processing mechanisms with different functions can be installed on the mobile frame 36; the number and position of the slide rail group 33 can also be changed according to the different workpieces to be processed, so as to achieve the purpose of processing versatility; the internal parts can be swapped, and because the structure is completely symmetrical on the left and right, the parts can also be interchangeable, and the interchangeable parts facilitate processing, installation and maintenance. And when processing different workpieces, if different processing methods are required, it is only necessary to replace the sawing mechanism and the drilling mechanism on the mobile frame with the mechanism that can realize the processing technology, such as: the reaming mechanism, etc. The movement path of the mechanism for processing the workpiece can also be realized by different slide rail groups 33, because the slide rail group limits the moving direction of the mobile frame 36.

[0047] Different mechanisms for processing workpieces are controlled by different driving devices, and can work simultaneously or separately, which reflects the flexibility of the utility model in processing workpieces; different mechanisms for processing workpieces are connected to different mobile brackets, the mobile bracket 36 is connected to the slider group 34, the slider group is embedded in the slide rail group 33, and different slide rails avoid the interference of the processing paths of the components.

[0048] When processing the automobile air guide strip, because the cross section and the mounting hole of the automobile air guide strip are parallel, the slide rail group 1 4 and the slide rail group 2 5 are also parallel, thereby ensuring that the cross section during sawing and the hole during drilling are parallel.

[0049] The slider group 34 and the slide rail group 33 can slide relative to each other, and their sizes and shapes are adapted. The slide rail group is provided with concave and convex grooves, which can ensure the movement direction and path of the slider, stable sliding, and improve the stability and safety of the machine tool; the slider group and the mobile frame 36 are fixedly connected, and bolts can be used to prevent dangerous components of the workpiece from falling; the mobile bracket is relatively high, so reinforcing ribs are provided in the vertical direction, which can enhance the structural strength and improve stability.

[0050] The upper part of the saw blade 14 is wrapped by a protective cover, and only the lower part of the saw blade is exposed to the outside, so as to prevent the upper part of the saw blade from accidentally scratching the operator, thus playing a protective role; similarly, the edges of the structure in the utility model are designed with rounded corners to protect the operator's safety, reduce stress concentration, and produce cracks, thereby enhancing the overall structural strength of the device.

[0051] A support is also added in the middle of the long side of the lower bracket seat 1 in the base 30, so that the base is more stable; secondly, the area of ​​the lower base plate is slightly larger than the lower bracket seat; the size of the lower base plate and the lower bracket seat is directly related to the size of the workpiece to be processed, and is suitable for processing the workpiece.

[0052] Each cylinder fixing block fixes the position of the cylinder to prevent its position from shifting during operation.

[0053] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model. Obviously, the present utility model is not limited to the above embodiments, and there are many variations. Any simple modification, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model should be considered to belong to the protection scope of the present utility model.
