Description

Technical Field

[0001] The utility model relates to the technical field of grinding machine processing, in particular to an adjustable clamp for a surface grinder. Background Art

[0002] A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other abrasive tools such as oilstones and abrasive belts and free abrasives for processing, such as honing machines, super finishing machines, belt grinders, grinders and polishing machines.

[0003] However, in the prior art, the existing surface grinder fixture can only clamp regular materials. If the material is an irregular object, the clamping jaws cannot effectively contact multiple surfaces of the material and cannot achieve effective clamping. Secondly, the existing surface grinder fixture cannot adjust the angle of the workpiece, resulting in the need to manually disassemble the workpiece and re-fix the rotation direction during the processing, which reduces the processing efficiency and affects practicality.

[0004] Therefore, an adjustable fixture for surface grinder is proposed to solve the above problems. Utility Model Content

[0005] The purpose of the utility model is to solve the problems existing in the prior art.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an adjustable clamp for a surface grinder, comprising: a protective shell, a limiting slide groove is formed through the bottom of the protective shell, and a plurality of fixing bolt holes are formed on both side surfaces of the inner cavity of the limiting slide groove, a limiting ring is fixedly installed at the center of the bottom of the inner cavity of the protective shell, a rotating assembly is arranged on both side surfaces of one end of the inner cavity of the protective shell, a U-shaped clamp is connected to the top of the rotating assembly, a limiting embedded ring is fixedly installed on the bottom of the U-shaped clamp, a plurality of support columns are fixedly connected to both sides of the top of the inner cavity of the U-shaped clamp, and a clamping assembly is arranged inside the U-shaped clamp.

[0007] As a preferred embodiment, the rotating assembly includes a worm, both ends of which are respectively embedded in both sides of one end of the inner cavity of the protective shell through bearings, both ends of the worm are fixedly connected with a knob, the surface of the worm is meshed with a worm gear ring, and the top of the worm gear ring is fixedly installed with a plurality of connecting columns, and the tops of the plurality of connecting columns are fixedly connected to the bottom of the U-shaped clamp.

[0008] As a preferred embodiment, the clamping assembly includes a bidirectional threaded rod and two limit columns, both ends of the bidirectional threaded rod are fixedly connected with knob 2, both ends of the bidirectional threaded rod and the limit column are movably sleeved with support plates, the surface of the support plate is provided with a plurality of through grooves, and the surface of the support plate is movably embedded with a plurality of sliding rods, the plurality of sliding rods are grouped in pairs, one end of each group of sliding rods is fixedly installed with a clamping panel, the other ends of the plurality of sliding rods are fixedly connected with a connecting block, and one end of the plurality of connecting blocks is fixedly installed with a spring.

[0009] As a preferred embodiment, the two ends of the bidirectional threaded rod are respectively embedded in the two side surfaces of the bottom of the inner cavity of the U-shaped splint through bearings, the two ends of the two limit columns are respectively fixedly connected to the two ends of the two side surfaces of the bottom of the inner cavity of the U-shaped splint, and the multiple through grooves are correspondingly movably sleeved on the surfaces of the multiple support columns, and one end of the multiple springs is fixedly connected to the side surface of the corresponding support plate.

[0010] As a preferred implementation, the bottom of the limiting insert ring is movably embedded in the interior of the limiting sleeve ring, and the limiting insert ring is located on the inner side of the worm gear ring.

[0011] As a preferred implementation, the plurality of clamping panels are located on top of a plurality of support columns.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. The utility model places the device on the mounting seat of the surface grinder, and can fix the device through the limiting slide groove and the fixing bolt hole. After the fixing is completed, the operation can be carried out. When the material needs to be ground, the material is placed on the top of multiple support columns, and then the second knob on one side is twisted. The rotation of the second knob drives the two-way threaded rod connected to it to rotate, and the rotation of the two-way threaded rod drives the support plates set at both ends to move in relative directions. At the same time, the two limiting columns are used to limit the support plates at both ends. The movement of the two support plates drives the multiple slide bars connected to the surface to move together until the multiple slide bars on both sides are in contact. When the spring moves to the surface of the material, continue to turn the second knob. The clamping panels on both sides are squeezed and move to the opposite sides, and both drive the corresponding connecting blocks and springs connected to themselves to move backward. When the spring moves backward, it automatically stores energy and rebounds to the clamping panel. At this time, the corresponding clamping panels can be squeezed by multiple springs to fix the material. Since the multiple clamping panels are not connected, when the material has an irregular shape, the material can also be fixed by making the multiple clamping panels contact each side of the material respectively. In this way, even if the material is an irregular object, the device can effectively contact multiple sides of the material to achieve effective clamping.

[0014] 2. According to the utility model, after a part of the material is ground, if it is necessary to rotate the angle to grind another part, one of the knobs 1 can be rotated. When the knob 1 is rotated, the worm connected to it is driven to rotate, and the rotation of the worm drives the worm gear ring meshing with it to rotate. The rotation of the worm gear ring drives the U-shaped clamping plate to rotate together through multiple connecting columns, and when the worm does not rotate, the worm gear ring can be limited to prevent it from rotating under force during grinding. The rotation of the U-shaped clamping plate drives the clamping assembly to rotate, and the limiting ring is embedded with a limiting ring to support and limit the U-shaped clamping plate. At this time, the material can be rotated in the same direction. By adopting this method, during the processing, when it is necessary to process the material in other directions, there is no need to constantly manually disassemble the workpiece, and only knob 1 needs to be rotated, thereby improving the processing efficiency.

[0026] Specifically: the whole device is supported by the protective shell 1, the device is fixed by the limiting slide groove 101 and the fixing bolt hole 102, the material is clamped by the rotating component 2, the limiting ring 103 is sleeved with the limiting ring 104 to provide support for the U-shaped clamp 3, the clamping component 4 is supported by the U-shaped clamp 3, and the material is quickly rotated by the clamping component 4.

[0027] In one embodiment, the rotating assembly 2 includes a worm 201, both ends of which are respectively embedded in both sides of one end of the inner cavity of the protective shell 1 through bearings, and both ends of the worm 201 are fixedly connected with a knob 202, and the surface of the worm 201 is meshed with a worm gear ring 203, and the top of the worm gear ring 203 is fixedly installed with multiple connecting columns 204, and the tops of the multiple connecting columns 204 are fixedly connected to the bottom of the U-shaped clamp 3.

[0028] Specifically: by rotating one of the knobs 202, the knob 202 drives the worm 201 connected thereto to rotate, and the rotation of the worm 201 drives the worm gear ring 203 meshing therewith to rotate, and the rotation of the worm gear ring 203 drives the U-shaped clamp 3 to rotate together through multiple connecting columns 204, and when the worm 201 does not rotate, the worm gear ring 203 can be limited to prevent it from rotating under force during grinding, and the rotation of the U-shaped clamp 3 drives the clamping assembly 4 to rotate, so that the material can be rotated in the direction.

[0029] In one embodiment, the clamping assembly 4 includes a bidirectional threaded rod 401 and two limit columns 403, both ends of the bidirectional threaded rod 401 are fixedly connected with a knob 2 402, both ends of the bidirectional threaded rod 401 and the limit column 403 are movably sleeved with a support plate 404, a plurality of through grooves 405 are opened through the surface of the support plate 404, a plurality of sliding rods 406 are movably embedded on the surface of the support plate 404, the plurality of sliding rods 406 are grouped in pairs, one end of each group of sliding rods 406 is fixedly installed with a clamping panel 407, the other ends of the plurality of sliding rods 406 are fixedly connected with a connecting block 408, and one end of the plurality of connecting blocks 408 is fixedly installed with a spring 409.

[0030] Specifically: by twisting the second knob 402 on one side, the second knob 402 rotates to drive the bidirectional threaded rod 401 connected thereto to rotate, and the rotation of the bidirectional threaded rod 401 drives the support plates 404 mounted at both ends thereof to move in relative directions, and at the same time, the two limiting columns 403 are used to limit the support plates 404 at both ends. The movement of the two support plates 404 drives the multiple sliding rods 406 connected to their surfaces to move together, until the multiple sliding rods 406 on both sides contact the surface of the material, and continue to turn the second knob 402. The clamping panels 407 on both sides are squeezed and moved to the opposite side, and both drive the connecting blocks 408 and springs 409 connected to themselves to move backward. When the spring 409 moves backward, it automatically stores energy and rebounds to the clamping panel 407. At this time, the multiple springs 409 can be used to squeeze the corresponding clamping panels 407 to fix the material. Since the multiple clamping panels 407 are not connected, when the shape of the material is irregular, the multiple clamping panels 407 can also be fixed by contacting each surface of the material.

[0031] In one embodiment, the two ends of the bidirectional threaded rod 401 are respectively embedded in the two side surfaces of the bottom of the inner cavity of the U-shaped clamp 3 through bearings, the two ends of the two limit columns 403 are respectively fixedly connected to the two ends of the two side surfaces of the bottom of the inner cavity of the U-shaped clamp 3, and multiple through grooves 405 are correspondingly movably sleeved on the surfaces of multiple support columns 301, and one end of multiple springs 409 is fixedly connected to one side surface of the corresponding support plate 404.

[0035] In one embodiment, the plurality of clamping panels 407 are each located on top of the plurality of support columns 301 .

[0036] Specifically, the plurality of clamping panels 407 are all located on the top of the plurality of support columns 301 , so that the plurality of clamping panels 407 will not hit the support columns 301 when moving.

[0037] Working principle: The device is placed on the mounting seat of the surface grinder, and can be fixed by the limiting slide groove 101 and the fixing bolt hole 102. After the fixing is completed, the operation can be carried out. When the material needs to be ground, the material is placed on the top of the multiple support columns 301, and then the knob 402 on one side is twisted. The knob 402 rotates to drive the two-way threaded rod 401 connected to it to rotate, and the two-way threaded rod 401 rotates to drive the support plates 404 mounted at both ends thereof to move in relative directions. At the same time, the two limiting columns 403 are used to adjust the support plates 404 at both ends. The two support plates 404 move to limit the position, and the movement of the two support plates 404 drives the multiple sliding bars 406 connected to the surface thereof to move together, until the multiple sliding bars 406 on both sides contact the surface of the material, and the knob 2 402 is continued to be turned, and the clamping panels 407 on both sides are squeezed to move to the opposite side, and both drive the connecting blocks 408 and springs 409 connected to themselves to move backward. When the springs 409 move backward, they automatically store energy and rebound to the clamping panels 407. At this time, the multiple springs 409 can be used to squeeze the corresponding clamping panels 407 to fix the material, and because the multiple clamping panels 407 are not connected. When the material is irregular in shape, the material can be fixed by making multiple clamping panels 407 contact various surfaces of the material respectively. In this way, even if the material is an irregular object, the device can effectively contact multiple surfaces of the material to achieve effective clamping. When a part of the material is polished, it is necessary to rotate the angle to polish another part. One of the knobs 202 can be rotated. When the knob 202 rotates, the worm 201 connected to it is driven to rotate. The rotation of the worm 201 drives the worm gear ring 203 meshing with it to rotate. The worm gear ring 203 The rotation drives the U-shaped clamping plate 3 to rotate together through multiple connecting columns 204, and the worm gear 201 can limit the worm gear ring 203 when it does not rotate to prevent it from rotating under force during grinding. The rotation of the U-shaped clamping plate 3 drives the clamping assembly 4 to rotate, and the limiting ring 104 is embedded with a limiting ring 103 to support and limit the U-shaped clamping plate 3. At this time, the material can be rotated in another direction. In this way, during the processing, when it is necessary to process the material in other directions, there is no need to manually disassemble the workpiece continuously. Only knob 1 202 needs to be rotated, which improves the processing efficiency.
