Description

Technical Field

[0001] The utility model relates to the field of fixtures and tools for grinding equipment, in particular to a fixture for a multi-angle grinder. Background Art

[0002] When grinding the die-casting parts of the shell, multiple surfaces need to be processed. Most existing fixtures cannot perform multi-angle positioning and grinding. For workpieces with multiple surfaces that need to be processed, it is impossible to complete the one-time grinding conditions of all surfaces except the installation surface.

[0003] Moreover, since the outer surface shapes of the workpieces are different, the existing fixtures, except for customized fixtures, are prone to the situation where the grinding surface of the workpiece is not facing the grinder after clamping the workpiece, which requires repositioning the workpiece or adjusting the angle of the fixture, and the overall adjustment steps are relatively cumbersome. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a clamp for a multi-angle grinder, comprising a workbench, a support seat rotatably installed on the workbench, a fixed seat is arranged on one side of the support seat, a driving pile is movably installed inside the fixed seat, an adjusting pile is rotatably connected to one side of the driving pile, and one side of the fixed seat has an opening, a plurality of clamping claws are rotatably arranged on a side of the adjusting pile close to the opening, the clamping claws and the adjusting pile are arranged at an angle, and a side of the clamping claw away from the workpiece is abutted against the opening, so that when the driving pile moves to a position away from the opening, the plurality of clamping claws clamp and fix the workpiece.

[0006] Furthermore, a plurality of connection holes are circumferentially formed on one side of the adjusting pile close to the opening, a connection plate is mounted on the connection holes, and the clamping claw is rotatably mounted on the connection plate.

[0007] Furthermore, a plurality of positioning grooves are provided at intervals on the outer circumference of the adjusting pile, a positioning rod is movably provided on one side of the fixing seat, and one end of the positioning rod is inserted into one of the positioning grooves.

[0008] Furthermore, the fixing seat is provided with a fixing ring along the circumferential direction, and the limiting ring is movably sleeved on the outer circumference of the fixing seat, and the inner side of the limiting ring matches the positioning rod, so that when one end of the positioning rod is inserted into the positioning groove, the other end presses against the inner side of the limiting ring.

[0009] Furthermore, a fixing plate is circumferentially arranged on the inner side of the fixing seat, a driving hole is opened on the fixing plate, and the driving pile is threadedly matched with the driving hole, so that when the driving pile rotates relative to the driving hole, the driving pile drives the adjusting pile to move.

[0010] Furthermore, the support seat has a built-in driving member, the output end of the driving member is connected to an outer tube, one side of the driving pile is connected to an inner tube, and the inner tube and the outer tube are movably matched so that the driving member drives the driving pile to rotate through the outer tube and the inner tube.

[0011] Furthermore, an anti-scratch ring is clamped at the opening, and an anti-scratch plate is connected to the side of the clamping jaw away from the workpiece, and the anti-scratch plate abuts against the anti-scratch ring.

[0012] Furthermore, a limit seat is movably arranged on the workbench, limit slots are provided on both sides of the support seat, and the limit slots are located in the rotation direction of the support seat, and limit blocks are arranged on both sides of the limit seat, and the limit blocks match the limit slots.

[0013] Furthermore, the inner side of the limiting groove is inclined, and the depth of one end of the limiting groove close to the limiting seat is greater than the depth of one end of the limiting groove away from the limiting seat.

[0014] The beneficial effect of the utility model is that when installing the workpiece, the support seat can be rotated relative to the workbench to a suitable loading angle, and the workpiece can be placed between the plurality of clamps, and then the driving pile is moved to a position away from the opening, so that the plurality of clamps are synchronously retracted toward the inside of the fixed seat with the adjusting pile. At this time, since one side of the clamp is the workpiece and the other side is the opening position, after the clamp is retracted to a certain stroke, the two sides of the clamp will respectively resist the opening position and the outer surface of the workpiece, so that the clamp can stably clamp the workpiece under the limit of the opening, and after the clamp completes the clamping and fixing, the operator can drive the adjusting pile to rotate relative to the driving pile by rotating the plurality of clamps, and then adjust the clamping angle of the workpiece to ensure that the grinding surface of the workpiece faces the position of the grinder.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field belong to the scope of protection of the utility model.

[0022] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms cannot be understood as limiting the present invention.

[0023] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0024] like Figure 1-5The utility model provides a clamp for a multi-angle grinder, comprising a workbench 1, a support seat 2 rotatably mounted on the workbench 1, a fixed seat 3 being arranged on one side of the support seat 2, a driving pile 4 being movably mounted inside the fixed seat 3, an adjusting pile 5 being rotatably connected to one side of the driving pile 4, and an opening 6 being provided on one side of the fixed seat 3, a plurality of clamping jaws 7 being rotatably arranged on a side of the adjusting pile 5 close to the opening 6, the clamping jaws 7 being inclined to the adjusting pile 5, and a side of the clamping jaws 7 away from the workpiece abutting against the opening 6, so that when the driving pile 4 moves to a position away from the opening 6, the plurality of clamping jaws 7 clamp and fix the workpiece.

[0025] When installing the workpiece, the support seat 2 can be rotated relative to the workbench 1 to a suitable loading angle, and the workpiece can be placed between the plurality of clamps 7. The driving pile 4 is then moved to a position away from the opening 6, so that the plurality of clamps 7 are synchronously retracted toward the inner side of the fixed seat 3 along with the adjusting pile 5. At this time, since one side of the clamp 7 is the workpiece and the other side is the opening 6 position, after the clamp 7 is retracted to a certain stroke, the two sides of the clamp 7 will respectively resist the opening 6 position and the outer surface of the workpiece, so that the clamp 7 can stably clamp the workpiece under the limit of the opening 6. At the same time, after the clamp 7 completes the clamping and fixing, the operator can drive the adjusting pile 5 to rotate relative to the driving pile 4 by rotating the plurality of clamps 7, and then adjust the clamping angle of the workpiece to ensure that the grinding surface of the workpiece faces the position of the grinder.

[0026] Among them, fixed blocks are arranged on both sides of the support seat 2, a rotating shaft is arranged between two adjacent fixed blocks, and the support seat 2 is sleeved on the rotating shaft so that the support seat 2 can rotate relative to the rotating shaft.

[0027] In one embodiment of the present solution, the opening 6 is arranged in a circular structure to ensure that the plurality of clamping jaws 7 can be rotated relative to the position of the opening 6 to adjust the grinding position of the workpiece.

[0028] Preferably, a plurality of connection holes 9 are circumferentially formed on one side of the adjustment pile 5 close to the opening 6 , a connection plate 10 is mounted on the connection holes 9 , and the clamping jaw 7 is rotatably mounted on the connection plate 10 .

[0029] Specifically, by passing connecting parts such as bolts through the connecting plate 10 and then fixing them to the connecting hole 9, the connecting plate 10 can be detachably installed on the side of the adjusting pile 5 close to the opening 6, and the stable connection of the clamp 7 is ensured. Moreover, since the clamp 7 is rotatably installed on the connecting plate 10, when the adjusting pile 5 drives the clamp 7 to move, the clamp 7 can rotate under the action of the limit of the opening 6, and clamp the workpiece.

[0030] Among them, due to the setting of the connecting hole 9, the operator can replace the clamping jaws 7 with different numbers and clamping methods to adapt to different workpiece clamping requirements.

[0031] In one embodiment of the present solution, a torsion spring is provided at the rotational connection between the clamping jaw 7 and the connecting plate 10 to ensure that the clamping jaw 7 can be automatically opened by the torsion spring, thereby facilitating the removal of the workpiece.

[0032] Preferably, a plurality of positioning grooves 11 are spaced apart on the outer circumference of the adjusting pile 5 , a positioning rod 12 is movably provided on one side of the fixing seat 3 , and one end of the positioning rod 12 is inserted into one of the positioning grooves 11 .

[0033] Specifically, when grinding the workpiece, it is necessary to move one end of the positioning rod 12 and insert it into the positioning groove 11, so that the circumference of the adjustment pile 5 is positioned by the positioning rod 12 to prevent the grinding surface of the workpiece from rotating on its own. At the same time, when adjusting the grinding surface of the workpiece, the positioning rod 12 can be moved away from the position of the positioning groove 11, so that the adjustment pile 5 can rotate relative to the driving pile 4, thereby facilitating the adjustment of the grinding surface of the workpiece. After the adjustment is completed, the adjustment pile 5 is positioned again by the positioning rod 12.

[0034] In one embodiment of the present solution, the adjustment pile 5 is provided with six positioning grooves 11 along the circumferential direction, and an angle of 60° is formed between two adjacent positioning grooves 11, so that the workpiece can have six grinding directions after being fixed.

[0035] It is worth mentioning that the positioning rod 12 in the present solution is used to limit the circumferential direction of the adjusting pile 5, but not the axial direction of the adjusting pile 5. When the driving pile 4 drives the adjusting pile 5 to move, even if the positioning rod 12 is inserted into the positioning groove 11, the adjusting pile 5 can still move away from or close to the position of the opening 6 to ensure that the fixed position of the clamping jaw 7 remains unchanged while the grinding surface of the workpiece remains unchanged.

[0036] Preferably, the fixing seat 3 is provided with a fixing ring 13 along the circumferential direction, and a limiting ring 14 is movably sleeved on the outer circumference of the fixing seat 3, and the inner side of the limiting ring 14 matches the positioning rod 12, so that when one end of the positioning rod 12 is inserted into the positioning groove 11, the other end abuts against the inner side of the limiting ring 14.

[0037] Specifically, when it is necessary to limit the positioning rod 12 to ensure the circumferential stability of the adjustment pile 5, the limiting ring 14 can be moved and mounted on the outer end of the positioning rod 12, so that the limiting ring 14 is against the outer end of the positioning rod 12, thereby ensuring that the positioning rod 12 will not separate from the positioning groove 11. When it is necessary to move the positioning rod 12, the limiting ring 14 is moved away from the outer end of the positioning rod 12, so that the positioning rod 12 can be moved conveniently.

[0038] Among them, due to the setting of the fixing ring 13, the limiting ring 14 can be placed on the fixing ring 13 when limiting the positioning rod 12, and then the limiting ring 14 is supported by the fixing ring 13 to ensure that the limiting ring 14 will not separate from one side of the positioning rod 12.

[0039] Preferably, a fixing plate 15 is circumferentially arranged on the inner side of the fixing seat 3, a driving hole 16 is opened on the fixing plate 15, and the driving pile 4 is threadedly matched with the driving hole 16, so that when the driving pile 4 rotates relative to the driving hole 16, the driving pile 4 drives the adjusting pile 5 to move.

[0040] Specifically, when the driving pile 4 needs to drive the adjusting pile 5 to move, the driving pile 4 rotates relative to the driving hole 16, and then the driving pile 4 moves axially relative to the driving hole 16 through threaded cooperation, so that the driving pile 4 drives the adjusting pile 5 to move stably, and during the rotation of the driving pile 4, due to the setting of the positioning rod 12, the adjusting pile 5 only moves with the driving pile 4 and does not rotate therewith.

[0041] Preferably, the support seat 2 has a built-in driving member 17, the output end of the driving member 17 is connected to an outer tube 18, one side of the driving pile 4 is connected to an inner tube 19, and the inner tube 19 and the outer tube 18 are movably matched, so that the driving member 17 drives the driving pile 4 to rotate through the outer tube 18 and the inner tube 19.

[0042] Specifically, when the driving pile 4 needs to be rotated, the driving member 17 is started so that the output end of the driving member 17 drives the outer tube 18 to rotate, and then the outer tube 18 drives the inner tube 19 to rotate, so that the driving pile 4 can be rotated. During the rotation of the driving pile 4, the outer tube 18 and the inner tube 19 will only expand and contract along the axial direction to ensure that when the driving pile 4 moves along the driving hole 16, the driving member 17 can maintain the driving effect on it.

[0043] The driving member 17 is a motor, a moving groove is provided inside the outer tube 18, a moving bar is provided outside the inner tube 19, and the moving bar cooperates with the moving groove to ensure that the outer tube 18 and the inner tube 19 will not produce circumferential relative rotation.

[0044] Preferably, an anti-scratch ring 20 is clamped at the opening 6 , and an anti-scratch plate 21 is connected to the side of the clamping jaw 7 away from the workpiece, and the anti-scratch plate 21 abuts against the anti-scratch ring 20 .

[0045] Specifically, since one side of the clamp 7 clamps and fixes the workpiece by abutting against the opening 6, and when the clamp 7 rotates relative to the opening 6 to adjust the grinding position of the workpiece, the side of the clamp 7 close to the opening 6 and the edge of the opening 6 will be worn. Therefore, the present invention provides an anti-scratch ring 20 and an anti-scratch plate 21 to reduce the degree of wear there.

[0046] In one embodiment of the present solution, the anti-scratch ring 20 and the anti-scratch plate 21 can be installed by bolting, bonding, magnetic attraction, etc. to ensure that they can be easily replaced later.

[0047] Preferably, a limit seat 22 is movably arranged on the workbench 1, limit grooves 23 are opened on both sides of the support seat 2, and the limit grooves 23 are located in the rotation direction of the support seat 2, and limit blocks 24 are arranged on both sides of the limit seat 22, and the limit blocks 24 match the limit grooves 23.

[0048] Specifically, when the support seat 2 needs to be rotated, the limit seat 22 is moved away from the support seat 2 to provide sufficient rotation space for the support seat 2. When the support seat 2 needs to be fixed, the support seat 2 is straightened and then the limit seat 22 is moved toward the support seat 2 so that the limit block 24 is buckled into the limit groove 23, and then the limit groove 23 is limited by the limit block 24 to ensure that the rotation direction of the support seat 2 is limited.

[0049] In one embodiment of the present solution, the limit seat 22 can be controlled to move by means of a cylinder cooperating with a guide rail.

[0050] Preferably, the inner side of the limiting groove 23 is inclined, and the depth of one end of the limiting groove 23 close to the limiting seat 22 is greater than the depth of one end of the limiting groove 23 away from the limiting seat 22 .

[0051] Specifically, due to the inclined setting of the limit groove 23 and the setting manner in which the depth of one end of the limit groove 23 close to the limit seat 22 is greater than the depth of the end of the limit groove 23 away from the limit seat 22, the limit block 24 can enter the limit groove 23 more easily, and as the limit seat 22 moves, the limit block 24 will eventually abut against the end of the limit groove 23 to ensure the limiting effect.

[0052] The present utility model is not limited to the above-mentioned optimal implementation mode. Anyone can derive other various forms of products under the inspiration of the present utility model. However, no matter what changes are made in the shape or structure, all those having the same or similar technical solutions as the present application fall within the protection scope of the present utility model.
