Description

Technical Field

[0001] This utility model relates to the technical field of deburring equipment, specifically a fixing fixture for a deburring machine. Background Technology

[0002] Deburring machines can be used to process various materials, including automotive parts, aerospace parts, electronic components, and mechanical parts. Their use can improve product quality and production efficiency, reduce errors and labor intensity caused by manual operation. However, when deburring machines process mechanical parts, special fixtures are required to help the deburring machine to perform burr removal operations more stably and efficiently.

[0003] Existing deburring machine fixtures often rely on two drive devices to bring the two side fixtures closer together to achieve the clamping of various workpieces, which has advantages such as reliable structure.

[0004] The existing fixtures for deburring machines have the following problems: the fixtures are one-piece structures that cannot be assembled, and cannot be combined according to the height and width of the workpieces. Furthermore, the fixtures are inadequate for handling irregularly shaped workpieces, have poor adaptability, and can only be coarsely adjusted without fine adjustment. The holding effect is often poor due to a lack of fine adjustment, and the processing preparation time is long. Therefore, we propose a new fixture for deburring machines. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the existing defects and provide a fixing fixture for a deburring machine, which can make more precise adjustment of the clamping force, has a simple structure, and a shorter processing preparation time, and can effectively solve the problems in the background art.

The right-angle support plate is installed between two assembly threaded holes by two assembly bolts. The screw is evenly threaded to the vertical plate of the right-angle support plate. The right end of the screw is provided with an adjustable clamping plate.

[0008] The reinforcing mechanism includes a reinforcing assembly screw, a pressure plate, a support block, and a reinforcing nut. The reinforcing assembly screw is threaded into one of the assembly thread holes. The pressure plate is inserted through the upper end of the reinforcing assembly screw. The support block is placed on the upper surface of the assembly plate. The upper surface of the support block and the lower surface of the pressure plate both have stepped surfaces at their front ends. The stepped surfaces of the pressure plate and the stepped surfaces of the support block are fitted together for installation.

[0009] Adjustment mechanism: It is located inside the pressure plate. With the help of the irregular clamping mechanism, it can quickly fix irregular workpieces. The assembled fixture can make reasonable responses according to the front and back width and vertical height of the workpiece. It has strong adaptability. After coarse adjustment, fine clamping adjustment can be made to make the clamping effect better. At the same time, the structure is simple and can significantly reduce the processing preparation time.

[0010] Furthermore, the irregular clamping mechanism also includes nuts. Nuts are threaded onto the outer right side surface of the first adjusting screw. The nuts are installed in conjunction with the right surface of the right-angle support plate to strengthen the cooperation and lock between the first adjusting screw and the right-angle support plate, making it safer.

[0011] Furthermore, the right-angle support plate is internally fixed with evenly distributed reinforcing ribs, which can enhance the rigidity of the right-angle support plate and increase safety.

[0012] Furthermore, each of the right end faces of the first adjusting screw is provided with a rotating ball, and each of the left center of the clamping plate is provided with a hemispherical groove. The rotating balls are rotatably connected to the hemispherical grooves that are laterally adjacent, which can tilt the clamping plate at a certain angle and clamp irregularly shaped parts.

[0013] Furthermore, the reinforcing mechanism also includes a reinforcing nut, which is threaded onto the upper end of the reinforcing assembly screw. The reinforcing nut is located at the upper end of the pressure plate and can strengthen the fixation of the workpiece.

[0014] Furthermore, the strengthening mechanism also includes a fixing screw and a fixing nut. The fixing screw is provided in the middle of the stepped surface of the support block, and a strip-shaped opening is provided in the middle of the stepped surface of the pressure plate. The fixing screw passes through the strip-shaped opening and is threaded with a fixing nut at the upper end, which can strengthen the fixation and increase safety.

[0015] Furthermore, the adjustment mechanism includes a second adjusting screw, a fine-tuning block, and springs. The left side of the pressure plate is provided with a threaded hole. The outer surface of the second adjusting screw is threadedly connected to the threaded hole. The right end of the second adjusting screw is rotatably connected to a squeezing inclined block. The inside of the pressure plate is provided with a T-shaped groove. The inner wall of the T-shaped groove is slidably connected to the upper end of the fine-tuning block. The upper end of the inner wall of the T-shaped groove is slidably connected to the squeezing inclined block laterally. The first inclined surface of the squeezing inclined block is slidably connected to the second inclined surface of the upper end of the fine-tuning block. Symmetrically distributed springs are fixedly connected between the top wall of the pressure plate and the lower end of the fine-tuning block, which can finely adjust the clamping force of the pressure plate.

[0016] Furthermore, the assembly plate has symmetrical loading and unloading holes on both the left and right sides, and symmetrical assembly openings on both the left and right sides, which facilitates installation and disassembly.

Detailed Implementation

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-5This embodiment provides a technical solution: a fixing fixture for a deburring machine, including an assembly plate 1, the upper surface of the assembly plate 1 is provided with uniformly distributed assembly threaded holes 4, the left and right sides of the assembly plate 1 are symmetrically provided with loading and unloading holes 3, the left and right sides of the assembly plate 1 are symmetrically provided with assembly openings 2, which can facilitate installation and disassembly, and also includes an irregular clamping mechanism 5, a reinforcing mechanism 6 and an adjusting mechanism 7.

[0029] The irregular clamping mechanism 5 includes a right-angle support plate 51, a first adjusting screw 52, ​​a clamping plate 53, and assembly bolts 55. The right-angle support plate 51 is installed between two assembly threaded holes 4 by two assembly bolts 55. The screw 52 is evenly threaded onto the vertical plate of the right-angle support plate 51. The right end of each screw 52 is provided with an adjustable clamping plate 53. The right end face of each first adjusting screw 52 is provided with a ball. The left center of each clamping plate 53 is provided with a hemispherical groove. The ball is rotatably connected to the horizontally adjacent hemispherical groove, which can tilt the clamping plate at a certain angle to clamp irregular parts. The irregular clamping mechanism 5 also includes nuts 54. Nuts 54 are threaded onto the right outer surface of each first adjusting screw 52. Nuts 54 are threaded onto the right outer surface of each right-angle support plate 51. The right surface of the right-angle support plate 51 is fitted together to strengthen the fit and lock between the first adjusting screw and the right-angle support plate, making it safer. The right-angle support plate 51 has evenly distributed reinforcing ribs inside, which can strengthen the rigidity of the right-angle support plate and enhance safety. The right-angle support plate 51 is installed with the corresponding assembly threaded holes 4 through two assembly bolts 55. The first adjusting screw 52 is rotated on the right-angle support plate 51 so that the sides of the three clamping plates 53 on both sides are close to the side of the workpiece until they are in complete contact. Because the hemispherical groove on the left side of the clamping plate 53 rotates relative to the ball on the right end face of the first adjusting screw 52, ​​it can completely fit the irregular workpiece. Then, the nut 54 is rotated until the nut 54 fits with the right surface of the right-angle support plate 51 to further fix the first adjusting screw 52.

[0030] The reinforcing mechanism 6 includes a reinforcing assembly screw 61, a pressure plate 62, a support block 63, and a reinforcing nut 64. The reinforcing assembly screw 61 is threaded into one of the assembly threaded holes 4. The upper end of the reinforcing assembly screw 61 is inserted through the pressure plate 62. The support block 63 is placed on the upper surface of the assembly plate 1. The upper surface of the support block 63 and the lower surface of the pressure plate 62 both have stepped surfaces at their front ends. The stepped surfaces of the pressure plate 62 and the support block 63 are fitted together. The reinforcing mechanism 6 also includes a reinforcing nut 64, which is threaded onto the upper end of the reinforcing assembly screw 61. The reinforcing nut 64 is located at the upper end of the pressure plate 62 and can strengthen the fixation of the workpiece. The reinforcing mechanism 6 also includes a fixing screw 65 and a fixing nut 66. The fixing screw 65 is located in the middle of the stepped surface of the support block 63. The stepped surface of the pressure plate 62 has a slot in the middle. The fixing screw 65 passes through the slot and is threaded onto the upper end of the fixing nut 66. The reinforcing assembly screw 61 is threaded into the corresponding assembly threaded hole 4, so that the through-hole of the pressure plate 62 passes through the upper end of the reinforcing assembly screw 61, and the lower surface of the support block 63 contacts the upper surface of the assembly plate 1. The stepped surface on the right side of the pressure plate 62 engages with the upper stepped surface of the support block 63. Then, the reinforcing nut 64 is rotated to press the pressure plate 62 tightly. (The engagement of the stepped surface on the right side of the pressure plate 62 with the upper stepped surface of the support block 63 and the downward pressure of the reinforcing nut 64 realize that the reinforcing assembly screw 61, the pressure plate 62 and the support block 63 constitute an assembly press.) At this time, the fixing screw 65 passes through the slot of the pressure plate 62. Then, the fixing nut 66 is rotated to press the upper end of the pressure plate 62 downward. (The width of the slot is smaller than the diameter of the opposite sides of the hexagon of the fixing nut 66. The slot exists to facilitate the adjustment of the front and rear position of the pressure plate 62.) The upper side of the workpiece is pressed and fixed by means of the reinforcing assembly screw 61, the pressure plate 62 and the support block 63.

[0031] Adjustment mechanism 7: Located inside pressure plate 62, adjustment mechanism 7 includes a second adjusting screw 71, a fine-tuning block 72, and a spring 73. A threaded hole is provided on the left side of pressure plate 62. The outer surface of the second adjusting screw 71 is threadedly connected to the threaded hole. A pressing wedge is rotatably connected to the right end of the second adjusting screw 71. A T-shaped groove is provided inside pressure plate 62. The inner wall of the T-shaped groove is slidably connected to the upper end of the fine-tuning block 72. The upper end of the inner wall of the T-shaped groove is laterally slidably connected to the pressing wedge. The first inclined surface of the pressing wedge is slidably connected to the second inclined surface of the upper end of the fine-tuning block 72. The second adjusting screw 71 can be rotated by rotating the knob at the left end of the second adjusting screw 71. This causes the extrusion block at the right end of the second adjusting screw 71 to press inward. The first inclined surface of the extrusion block causes the second inclined surface of the fine-tuning block 72 to be subjected to extrusion force, thus moving downward. A symmetrically distributed spring 73 is fixedly connected between the top wall of the pressure plate 62 and the lower end of the fine-tuning block 72. The second adjusting screw 71 can be rotated appropriately. The second adjusting screw 71 moves to the right, causing the extrusion block to slide on the right side of the upper end of the inner wall of the T-shaped slide groove. Because the first inclined surface of the extrusion block and the second inclined surface of the fine-tuning block 72 press backward, the fine-tuning block 72 moves downward, further fine-tuning and pressing the upper surface of the workpiece. During this process, the spring 73 extends. After the workpiece is fixed, it can be easily processed for the next step.

[0032] The working principle of the fixing fixture for a deburring machine provided by this utility model is as follows: When using the fixing fixture for this deburring machine, the operator first needs to install the assembly plate 1 onto the machine tool processing platform through the external bolts and nuts passing through the loading and unloading holes 3. Then, the workpiece is placed on the upper surface of the assembly plate 1. According to the requirements, the right-angle support plate 51 can be installed through two assembly bolts 55 and the corresponding assembly threaded holes 4. The first adjusting screw 52 is rotated on the right-angle support plate 51 to make the sides of the three clamping plates 53 on both sides close to the sides of the workpiece until they are in complete contact. Because the hemispherical groove on the left side of the clamping plate 53 is in contact with the first adjusting screw... The ball on the right end face of 52 rotates relative to the workpiece, allowing it to fully conform to the irregular shape. Then, rotate nut 54 until it conforms to the right surface of right-angle support plate 51, further securing the first adjusting screw 52. Next, thread the reinforcing assembly screw 61 to the corresponding assembly threaded hole 4, allowing the through-hole of pressure plate 62 to pass through the upper end of reinforcing assembly screw 61, bringing the lower surface of support block 63 into contact with the upper surface of assembly plate 1. The stepped surface on the right side of pressure plate 62 engages with the upper stepped surface of support block 63. Then, rotate reinforcing nut 64 to tighten pressure plate 62 (the stepped surface on the right side of pressure plate 62 engages with the upper stepped surface of support block 63). The side stepped surface engagement support and the downward pressure of the reinforcing nut 64 realize the assembly of the reinforced assembly screw 61, pressure plate 62 and support block 63 into an assembled press. At this time, the fixing screw 65 passes through the slot of the pressure plate 62, and then the fixing nut 66 is rotated to press down the upper end of the pressure plate 62 (the width of the slot is smaller than the diameter of the opposite sides of the hexagon of the fixing nut 66, and the slot exists to facilitate the adjustment of the front and rear position of the pressure plate 62). The workpiece is pressed and fixed on the upper side by means of the reinforcing assembly screw 61, pressure plate 62 and support block 63. After that, according to the needs, the second adjusting screw 71 can be rotated appropriately, and the second adjusting screw 71 moves to the right. The moving extrusion sloping block slides to the right side of the upper end of the inner wall of the T-shaped slide groove. Because the first inclined surface of the extrusion sloping block and the second inclined surface of the upper end of the fine adjustment pressure block 72 are pressed backward, the fine adjustment pressure block 72 moves down, further fine-tuning and pressing the upper surface of the workpiece. During this process, the spring 73 extends. After the workpiece is fixed, it can be easily processed for the next step. After processing is completed, the second adjusting screw 71 can be rotated in the opposite direction. The extrusion sloping block moves to the left. The fine adjustment pressure block 72 moves up under the action of the spring 73 after the extrusion is reduced. Loosen the fixing nut 66 and the reinforcing nut 64, disassemble the reinforcing mechanism 6, loosen the nut 54, and rotate the first adjusting screw 52 in the opposite direction to release the workpiece.
