Description

Technical Field

[0001] This utility model relates to the field of grinding equipment technology, specifically to a deburring machine for workpiece grooves. Background Technology

[0002] In the process of parts manufacturing, metal cutting equipment is typically used to perform multiple processes on metal sheets to complete the parts. For example, metal sheets are cut into specific shapes, recessed areas are stamped on their surfaces, and grooves are formed by stamping. Figure 7 The image shows a type of part available on the market, which is manufactured through multiple processes to achieve the desired shape. Figure 7 As shown in the diagram, in the above-mentioned type of parts, there will be certain burrs on the parts after metal processing, which will affect the normal use of the parts. Therefore, it is necessary to grind and remove the burrs on the parts. However, the groove 002 part processed by stamping or cutting on the side is a concave structure. Therefore, the grinding process of the burrs on the edge of the groove 002 is relatively cumbersome. In some manufacturers, manual grinding is required. Furthermore, in the process of grinding the burrs inside the groove 002, the grinding tool needs to be inserted into the groove 002. Due to the size of the groove 002, the efficiency of burr grinding is affected.

[0003] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this utility model is to provide a deburring machine for workpiece grooves to solve the above-mentioned technical problems. The technical solution adopted by this utility model is as follows: A deburring machine for workpieces with grooves on their side edges is provided for deburring workpieces. The machine includes a machine base on which the following components are mounted: A fixture assembly for positioning a workpiece to be processed, the fixture assembly including a fixture plate that reciprocates in a vertical direction, a fixed plane for supporting and positioning the workpiece to be processed is provided on the fixture plate, and a plurality of clearance grooves corresponding to the grooves are formed on the edge of the fixture plate, and the clearance grooves have several dimensions smaller than the grooves. The deburring mechanism is provided with a plurality of deburring mechanisms corresponding to the grooves respectively, and arranged around the side of the fixture assembly. Each deburring mechanism includes a frame and a grinding machine that reciprocates toward the fixture assembly. The end of the grinding machine is provided with a grinding head that is embedded in the groove.

[0005] Furthermore, the fixture assembly also includes: A vertical plate, which is fixedly mounted on the machine base in a vertical direction; A base plate, which is slidably connected to the vertical plate in the vertical direction, and the fixture plate is detachably mounted on the upper end of the base plate; A lifting cylinder is fixedly mounted on the machine base and is connected to the base plate for transmission, driving the base plate to reciprocate in the vertical direction.

[0006] Furthermore, a connecting block is fixedly connected to the piston rod of the lifting cylinder, the connecting block including a convex ring protruding in the circumferential direction; a docking piece is fixedly installed on the base plate, the docking piece having a groove formed therein for the convex ring to be inserted, and a channel for the piston rod of the lifting cylinder to pass through is provided at the lower edge of the groove.

[0007] Furthermore, the fixture plate has several positioning grooves formed on its fixed plane for the protrusions of the workpiece to be processed to be embedded therein.

[0008] Furthermore, the lifting cylinder is a two-stage cylinder, and when the lifting cylinder drives the fixture plate to the initial position, the fixture plate is lower than the plane where the grinder is located. When the lifting cylinder drives the fixture plate to rise for the first stage, the fixture plate corresponds to the grinder. When the lifting cylinder drives the fixture plate to rise for the second stage, the fixture plate is positioned above the height plane of the grinder.

[0009] Furthermore, the deburring mechanism also includes a sliding block slidably connected to the top of the frame and a movable cylinder fixedly mounted on the frame and pulsatorically connected to the sliding block, with the grinder mounted on the sliding block.

[0010] Furthermore, a mounting base is fixedly provided on the sliding block, and the grinder is detachably mounted on the mounting base. The mounting base includes: The base is fixedly mounted on the sliding block; A clamping member is disposed on the base body. The clamping member includes a mounting part and a clamping part connected to the mounting part by bolts. Both the mounting part and the clamping part are provided with a semi-groove for clamping the grinder.

[0011] The beneficial effects of this utility model are as follows: During deburring, the workpiece is placed on the fixed surface of the fixture plate and positioned on the fixed plane. The deburring mechanism is arranged around the fixture assembly and corresponds to the grooves on the workpiece. When the grinder moves towards the workpiece, the grinding head extends into the groove. As the grinder drives the grinding head to rotate, it can grind the burrs on the inner wall of the groove. The fixture plate is provided with several clearance grooves corresponding to the grooves. At the same time, the geometric dimensions of the clearance grooves are smaller than the geometric dimensions of the grooves. During the grinding process of the grinding head rotating inside the groove, it can suppress the degree of the grinding head protruding from the groove. This allows the grinding head to deform under the constraint of the smaller geometric dimensions of the inner wall of the clearance groove, thereby improving the grinding effect on the groove. The grinding head is composed of bundled metal wire brushes, which can continuously brush the inner wall of the groove during rotation and be squeezed and deformed under the constraint of the inner wall of the clearance groove, thus completing the grinding operation more effectively.

[0012] This technical solution positions the part on a fixture assembly and uses multiple deburring mechanisms arranged around the fixture assembly to simultaneously insert grinding heads into the grooves to grind the burrs. This achieves a rapid deburring effect, greatly reduces the labor intensity of operators, and improves the efficiency of burr grinding. Attached Figure Description

Detailed Implementation

[0021] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0022] This technical solution provides a deburring machine for workpieces with grooves 002, used to perform deburring operations on parts with several grooves 002 along their edges, such as... Figure 7 As shown, this is a part manufactured using metal cutting technology. Several grooves 002 are provided along the edge of the part. Because the grooves 002 are embedded, manual deburring requires inserting a deburring device into the grooves 002. Due to the limited internal dimensions of the grooves 002, the efficiency of deburring burrs within the grooves is low, and the labor intensity is high. This technical solution positions the part on a fixture assembly 200, and uses multiple deburring mechanisms 300 arranged around the fixture assembly 200 to simultaneously insert grinding heads 321 into the grooves 002 to grind the burrs. This achieves rapid deburring, significantly reducing the labor intensity of operators and improving the efficiency of deburring.

[0023] Specifically, such as Figure 1-6As shown, this technical solution provides a workpiece groove 002 deburring machine for deburring workpieces with several grooves 002 on their side edges. It includes a machine base 100, a fixture assembly 200, and a deburring mechanism 300 mounted on the machine base 100. The fixture assembly 200 is used to position the workpiece to be processed. The fixture assembly 200 includes a fixture plate 210 that reciprocates vertically. A fixed flat grate 211 is mounted on the fixture plate 210 to support and position the workpiece to be processed. The edge of the fixture 210 is formed with several clearance grooves 212 corresponding to the grooves 002, and the clearance grooves 212 have several dimensions smaller than the grooves 002; the deburring mechanism 300 is provided with multiple ones corresponding to the grooves 002, and is arranged around the side of the fixture assembly 200. Each deburring mechanism 300 includes a frame 310 and a grinder 320 that reciprocates toward the fixture assembly 200. The end of the grinder 320 is provided with a grinder head 321 that is embedded in the groove 002.

[0024] During the deburring process, the workpiece to be processed is placed on the fixed surface of the jig plate 210 and positioned and fixed on the fixed flat mantle 211, such as... Figure 7As shown, several bent portions are provided at the edge of the part to be processed, bending downwards. After the part to be processed is placed on the fixed flat panel 211, the bent portions adhere to the side wall of the fixture plate 210, thereby restricting the horizontal movement of the part to be processed. The deburring mechanism 300 is arranged around the fixture assembly 200 and corresponds to the grooves 002 on the part to be processed. When the grinder 320 moves towards the part to be processed, the grinding head 321 extends into the groove 002, and grinding is performed. During the rotation of the grinding head 321 driven by the machine 320, burrs on the inner wall of the groove 002 can be ground. It is worth noting that the fixture plate 210 is provided with several relief grooves 212 corresponding to the groove 002. At the same time, the geometric dimensions of the relief grooves 212 are smaller than the geometric dimensions of the groove 002. During the grinding process of the grinding head 321 rotating inside the groove 002, the degree to which the grinding head 321 leaks out of the groove 002 can be suppressed, thereby allowing the grinding head 321 to be ground within the smaller geometric dimension. The inner wall of the clearance groove 212 restricts deformation, improving the grinding effect on the groove 002. It's worth noting that the grinding head 321 is composed of bundled metal wire brushes, which continuously brush the inner wall of the groove 002 during rotation. Furthermore, it is compressed and deformed under the restriction of the inner wall of the clearance groove 212, thus completing the grinding operation more effectively. Without the clearance groove 212, one end of the groove 002 of the workpiece is closed. In this case, the grinding head 321 extends into the groove from the side. After entering the groove 002, one side of the grinding head 321 is restricted by the fixed flat mantle 211 of the jig plate 210, which causes the grinding head 321 to be flattened. This will affect the rotation of the grinding head 321 and accelerate the wear of the grinding head 321. After setting the geometric dimensions of the clearance groove 212 to be the same as or larger than the geometric dimensions of the groove 002, the edge of the clearance groove 212 cannot restrict the grinding head 321. Therefore, the cleaning effect of burrs is poor during the rotation of the grinding head 321.

[0025] In this embodiment, as Figure 2-4 As shown, the fixture assembly 200 also includes a vertical plate 201, a base plate 202, and a lifting cylinder 203. The vertical plate 201 is fixedly mounted on the machine base 100 in a vertical direction. The base plate 202 is slidably connected to the vertical plate 201 in a vertical direction, and the fixture plate 210 is detachably mounted on the upper end of the base plate 202. The lifting cylinder 203 is fixedly mounted on the machine base 100 and is connected to the base plate 202 in a transmission connection, driving the base plate 202 to reciprocate in a vertical direction.

[0026] Furthermore, when the lifting cylinder 203 is detachably connected to the base plate 202, the following structure is adopted, such as... Figure 3-4As shown, a connecting block 204 is fixedly connected to the piston rod of the lifting cylinder 203. The connecting block 204 includes a protruding ring 205 protruding in the circumferential direction. A docking piece 206 is fixedly installed on the base plate 202. A groove 207 is formed on the docking piece 206 for the protruding ring 205 to be inserted therein. A channel 208 for the piston rod of the lifting cylinder 203 to pass through is provided at the lower edge of the groove 207.

[0027] The base plate 202 is driven by the lifting cylinder 203 to move back and forth in the vertical direction, thereby raising the jig plate 210 and the workpiece to be processed, so that it is positioned corresponding to the deburring mechanism 300, which facilitates the deburring operation of the workpiece.

[0028] In this technical solution, in order to ensure the reliability of the workpiece placed on the fixture plate 210, a number of positioning grooves 213 are formed on the fixing flat 211 of the fixture plate 210 for the protrusions of the workpiece to be processed to be embedded therein.

[0029] In this technical solution, during the process of the grinding head 321 extending into or retracting from the groove 002, the impact on the workpiece placed on the fixture plate 210 is reduced, and the workpiece is prevented from shaking due to being moved. In this embodiment, the lifting cylinder 203 is a two-stage cylinder. When the lifting cylinder 203 drives the fixture plate 210 to the initial position, the fixture plate 210 is lower than the flat mantle 211 where the grinding machine 320 is located. When the lifting cylinder 203 drives the fixture plate 210 to rise for the first stage, the fixture plate 210 corresponds to the grinding machine 320. When the lifting cylinder 203 drives the fixture plate 210 to rise for the second stage, the fixture plate 210 is positioned at a height higher than the flat mantle 211 of the grinding machine 320.

[0030] During the deburring process of the workpiece, the lifting cylinder 203 continuously drives the fixture plate 210 upwards at both ends of its stroke, bringing it to its highest position. This allows the workpiece to be loaded onto the fixture plate 210. Subsequently, the lifting cylinder 203 drives the fixture plate 210 downwards at both ends of its stroke, returning it to the starting position. During processing, the pre-grinding machine 320 moves towards the fixture assembly 200, causing the grinding head 321 to move to a position corresponding to the groove 002. At this point, the workpiece is located below the grinding head 321. The lifting cylinder 203 drives the fixture plate 210 upwards, raising it to a certain stroke, so that the groove 002 and the grinding head 321 correspond to each other. During the upward movement, the grinding head 321 can extend into the groove 002. It is worth noting that when extending the grinding head 321... During the process of entering the groove 002, the workpiece is moved from bottom to top, causing the grinding head 321 to extend into the groove 002. During this process, the workpiece receives downward pressure from the grinding head 321, thus pressing the workpiece onto the fixture plate 210 while the grinding head 321 is inserted into the groove 002, ensuring the stability of the workpiece. After burr removal, the lifting cylinder 203 drives the fixture plate 210 upward for a second stroke, causing the fixture plate 210 to rise. During the rising process, the grinding head 321 passes through the clearance groove 212 and separates from the groove 002. During this process, the grinding head 321 applies downward pulling force to the workpiece, thus pressing the workpiece onto the fixture plate 210, again ensuring the stability of the workpiece.

[0031] In this technical solution, when the grinder 320 is driven towards the fixture assembly 200, in order to achieve rapid driving action, the deburring mechanism 300 also includes a sliding block 301 slidably connected to the top of the frame 310 and a movable cylinder 302 fixedly mounted on the frame 310 and driven by the sliding block 301. The grinder 320 is mounted on the sliding block 301. Driven by the movable cylinder 302, the grinder 320 can move rapidly.

[0032] In this technical solution, such as Figure 5-6As shown, to facilitate the installation of the grinder 320, a mounting base 330 is fixedly installed on the sliding block 301. The grinder 320 is detachably mounted on the mounting base 330. The mounting base 330 includes a base body 331 and a clamping member 332. The base body 331 is fixedly mounted on the sliding block 301. The clamping member 332 is mounted on the base body 331 and includes a mounting part 333 and a clamping part 334 bolted to the mounting part 333. Both the mounting part 333 and the clamping part 334 are provided with semi-grooves 335 for clamping the grinder 320. That is, by tightening or loosening the bolts, the distance between the two semi-grooves 335 can be adjusted, thereby clamping or releasing the grinder 320 within the two semi-grooves 335, completing the loading and unloading of the grinder 320.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the present utility model without departing from the scope of the present utility model shall fall within the scope of the present utility model.
