Description

Technical Field

[0001] The utility model relates to the technical field of metal parts processing, in particular to an adjustable clamp used for parts processing. Background Art

[0002] Metal parts refer to the metal blocks, metal bars, metal tubes, etc. of various specifications and shapes made of metal materials. Fixtures are devices used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. They are also called fixtures. In a broad sense, any device used to quickly, conveniently and safely install the workpiece in any process of the process can be called a fixture.

[0003] With the continuous improvement of science and technology, the mechanical processing industry is also increasing, and processing inclined holes on parts is a difficult point in the mechanical manufacturing process. In the existing technology, there are two most commonly used methods for processing inclined holes. One is to use inclined irons of different angles to stack and arrange them into an inclined whole with the required processing angle, and then fix the parts to be processed on the inclined iron whole. This method has technical problems such as difficulty in pressing the parts to be processed, safety hazards during processing, and inability to piece together any inclined hole angle. Another method is to directly manufacture inclined irons according to the inclined hole angle to adjust the direction of the inclined hole processed on the parts to be the same as the drill bit of the drilling equipment. This method has technical problems such as a single inclined hole angle and low fixture utilization.

[0004] Therefore, it is necessary to provide an adjustable fixture for parts processing to solve the above technical problems. Utility Model Content

[0005] In order to overcome the above shortcomings, the purpose of the utility model is to provide an adjustable fixture for parts processing, which has a simple structure and can realize arbitrary inclined hole processing of parts on the fixture by drilling equipment, thereby improving the working efficiency of inclined hole processing.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is: an adjustable fixture for parts processing, including a workbench, a jig plate and a horizontal driving member; the jig plate is hinged to the angle adjustment assembly through a connecting support frame, and the angle adjustment assembly includes symmetrically arranged inclined plane brackets and a movable guide rod connecting two inclined plane brackets and capable of moving along the upper inclined planes thereof, the hinged end 1 on the connecting support frame and the driving end on the horizontal driving member are both hinged to the movable guide rod, and when the horizontal driving member drives the movable guide rod to move back and forth, the jig plate can swing back and forth with the hinged end 2 on the connecting support frame as a fulcrum.

[0007] The side of the L-shaped long side of the connecting support frame that is away from the short side is detachably connected to the jig plate. The connecting support frame uses the second hinge end as a fulcrum, and the horizontal driving member drives the first hinge end of the connecting support frame to swing back and forth along the fulcrum to adjust the angle between the jig plate and the horizontal plane, thereby meeting different inclined hole processing requirements. The connecting support frame is arranged in an L shape, and the ends on the two sides thereof that are far away from each other are the first hinge end and the second hinge end respectively.

[0008] Furthermore, a support seat is provided on both sides of the length direction of the horizontal driving member, the support seat is parallel to the driving direction of the horizontal driving member, and the second hinge end is hinged to the support seat. By providing the support seat to provide a support point for the connecting support frame, the subsequent connecting support frame can swing back and forth with the hinge end as the fulcrum.

[0009] Furthermore, a strip groove is provided on the support seat along its length direction, and the second hinge end can move back and forth along the strip groove, and a waste collection box is provided on the side of the workbench close to the second hinge end. After the inclined hole of the workpiece is processed, the horizontal driving member continues to drive the moving guide rod to move along the inclined support, and at the same time, the second hinge end also continues to move horizontally along the strip groove until it moves to the waste collection box. At this time, the angle between the jig plate and the horizontal plane reaches the maximum, and the processing waste remaining on the jig plate can slide into the waste collection box along the jig plate under the action of gravity, effectively reducing the subsequent cleaning intensity of the staff.

[0010] Furthermore, the inclined bracket is arranged along the driving direction of the horizontal driving member, and the downward inclination direction of the upper surface of the inclined bracket is opposite to the moving direction of the jig plate. Therefore, when the movable guide rod moves upward in an inclined direction close to the external drilling device, the jig plate also swings in a direction close to the external drilling device, thereby adjusting the drilling angle while making the product to be processed close to the external drilling device, facilitating the drilling operation.

[0011] Furthermore, a guide plate is provided on the upper surface of the inclined plane bracket, a guide groove is provided on the guide plate along the inclined direction of the inclined plane bracket, and both ends of the movable guide rod are respectively located in a guide groove. The guide groove is provided to provide guidance for the movement of the movable guide rod.

[0012] Furthermore, a limit assembly is provided on the jig plate, and the limit assembly includes two limit members, an abutment plate, and a limit drive member. The abutment plate is located at the lower part of the jig plate and is detachably connected to the jig plate. The two limit members are located at both ends of the jig plate. The driving end of the limit drive member is provided with a push plate, and the push plate can press the part to be processed onto the abutment plate. A limited space for the part to be processed is formed between the two limit members, the abutment plate, and the limit drive member. The limit member is used to limit the movement of the part to be processed in the left and right directions, and the limit drive member and the abutment plate are used to limit the movement of the part to be processed in the up and down directions. This ensures that the position of the part to be processed on the jig plate will not be offset, thereby avoiding affecting the subsequent opening effect of the inclined hole.

[0013] Furthermore, the jig plate is provided with a slot for inserting the abutment plate, and the abutment plate is interference fit with the slot, and a plurality of guide rollers are provided on the opposite sides of the two limit members along their length direction, and a clearance groove is provided at the bottom of the jig plate. The abutment plate is perpendicular to the jig plate, and the setting of the guide rollers makes it possible for the movement of the part to be processed to be smoother when the limit drive member drives the push plate to press the part to be processed toward the abutment plate, thereby avoiding wear on both sides of the part to be processed. The detachable setting of the abutment plate and the jig plate makes it convenient for the staff to clean the surface of the jig plate and the abutment plate after removing the abutment plate.

[0014] Furthermore, a hinged seat is provided at the driving end of the horizontal driving member, and the hinged seat is hinged to the movable guide rod through a hinged frame. The movable guide rod extends out of two connecting support frames, and a limit block is provided at both ends thereof.

[0015] Beneficial effects of the utility model:

[0016] In the utility model, the horizontal driving member, the angle adjustment component and the jig plate cooperate with each other. When the horizontal driving member drives the movable guide rod to move along the inclined direction of the inclined plane bracket, the jig plate can swing to an inclined angle that meets the inclined hole parameters with the hinged end two connected to the support frame as a fulcrum, thereby realizing automatic adjustment of the angle of the jig plate, thereby changing the relative position of the part to the external drilling equipment. The structure is simple, and the drilling equipment can realize arbitrary inclined hole processing of the part on the fixture, thereby improving the working efficiency of the inclined hole processing.

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0023] See attached Figures 1 to 4 As shown, an adjustable fixture for parts processing in this embodiment includes a workbench 1, a jig plate 7 and a horizontal driving member 2; the jig plate 7 is hinged to the angle adjustment component 3 through a connecting support frame 4, and the angle adjustment component 3 includes symmetrically arranged inclined plane brackets 32 and a movable guide rod 35 connecting two inclined plane brackets 32 and movable along the upper inclined planes thereof, the hinge end 41 on the connecting support frame 4 and the driving end on the horizontal driving member 2 are both hinged to the movable guide rod 35, and when the horizontal driving member 2 drives the movable guide rod 35 to move back and forth, the jig plate 7 can swing back and forth with the hinge end 42 on the connecting support frame 4 as a fulcrum.

[0024] The side of the L-shaped long side of the connecting support frame 4 that is away from the short side is detachably connected to the fixture plate 7. The connecting support frame 4 uses the hinge end 2 42 as a fulcrum, and the horizontal driving member 2 drives the hinge end 1 41 on the connecting support frame 4 to swing back and forth along the fulcrum to adjust the angle between the fixture plate 7 and the horizontal plane, thereby meeting different inclined hole processing requirements. The connecting support frame 4 is L-shaped, and the ends on the two sides thereof that are far away from each other are the hinge end 1 41 and the hinge end 2 42 respectively.

[0025] In some embodiments, threaded holes are provided on the connecting support frame 4 and the jig plate 7, and the two are locked by sinking screws so that the two are detachable, thereby facilitating the staff to quickly replace different jig plates 7, so that the adjustable clamp can be adapted to the processing of inclined holes of different types of products to be processed, effectively improving its applicability.

[0026] The horizontal driving member 2 is a horizontal driving cylinder or a horizontal driving module, including but not limited to the above two mechanical driving structures, as long as it is a known mechanical structure that can drive the movable guide rod 35 to move back and forth.

[0027] A support seat 5 is provided on both sides of the length direction of the horizontal driving member 2, and the support seat 5 is parallel to the driving direction of the horizontal driving member 2. The hinge end 2 42 is hinged to the support seat 5. By providing the support seat 5 to provide a support point for the connecting support frame 4, the subsequent connecting support frame 4 can swing back and forth with the hinge end as a fulcrum.

[0028] The support seat 5 is provided with a strip groove 6 along its length direction, and the hinged end 2 42 can move back and forth along the strip groove 6. A waste collection box is provided on the side of the workbench 1 close to the hinged end 2 42. After the inclined hole of the workpiece is processed, the horizontal driving member 2 continues to drive the moving guide rod 35 to move along the inclined support 32. At the same time, the hinged end 2 42 also continues to move horizontally along the strip groove 6 until it moves to the waste collection box. At this time, the angle between the jig plate 7 and the horizontal plane reaches the maximum. The processing waste remaining on the jig plate 7 can slide into the waste collection box along the jig plate 7 under the action of gravity, effectively reducing the subsequent cleaning intensity of the staff.

[0029] The inclined bracket 32 ​​is arranged along the driving direction of the horizontal driving member 2, and the downward inclination direction of the upper surface of the inclined bracket 32 ​​is opposite to the moving direction of the jig plate 7. Therefore, when the movable guide rod 35 moves upward in an inclined direction close to the external drilling equipment, the jig plate 7 also swings in a direction close to the external drilling equipment, thereby adjusting the drilling angle while making the product to be processed close to the external drilling equipment, facilitating the drilling operation.

[0030] A guide plate 33 is disposed on the upper surface of the inclined plane bracket 32. A guide groove 34 is provided on the guide plate 33 along the inclined direction of the inclined plane bracket 32. Both ends of the movable guide rod 35 are respectively located in a guide groove 34. The guide groove 34 is provided to provide guidance for the movement of the movable guide rod 35.

[0031] The jig plate 7 is provided with a limit assembly, which includes two limit members 8, an abutment plate 10 and a limit drive member 12. The abutment plate 10 is located at the lower part of the jig plate 7 and is detachably connected to the jig plate 7. The two limit members 8 are located at both ends of the jig plate 7. The driving end of the limit drive member 12 is provided with a push plate 13, and the push plate 13 can press the part to be processed onto the abutment plate 10. A limited space for the part to be processed is formed between the two limit members 8, the abutment plate 10 and the limit drive member 12. The limit member 8 is used to limit the movement of the part to be processed in the left and right directions, and the limit drive member 12 and the abutment plate 10 are used to limit the movement of the part to be processed in the up and down directions. This ensures that the position of the part to be processed on the jig plate 7 will not be offset, thereby avoiding affecting the subsequent opening effect of the inclined hole.

[0032] The limit drive member 12 is a limit drive cylinder, and the piston rod of the limit cylinder is extended and retracted to control the push plate 13 to press the workpiece to be processed toward the abutment plate 10. It should be noted that the limit drive member 12 is not limited to a cylinder, and can also be other known mechanical structures that can push the push plate 13 to move.

[0033] The jig plate 7 is provided with a slot for inserting the abutment plate 10, and the abutment plate 10 is interference fit with the slot. A plurality of guide rollers 9 are provided on the opposite sides of the two limit members 8 along their length direction, and a clearance groove 11 is provided at the bottom of the jig plate 7. The abutment plate 10 is perpendicular to the jig plate 7. The setting of the guide rollers 9 makes it possible for the movement of the parts to be processed to be smoother when the limit drive member 12 drives the push plate 13 to press the parts to be processed toward the abutment plate 10, thereby avoiding wear on both sides of the parts to be processed. The detachable setting of the abutment plate 10 and the jig plate 7 makes it convenient for the staff to clean the surface of the jig plate 7 and the abutment plate 10 after removing the abutment plate 10.

[0034] The driving end of the horizontal driving member 2 is provided with an articulated seat 31 , and the articulated seat 31 is hinged to a moving guide rod 35 through an articulated frame 36 . The moving guide rod 35 extends out of two connecting support frames 4 , and a limit block 37 is provided at each end.

[0035] Working principle:

[0036] When processing an inclined hole on a part, first place the part to be processed on the jig plate 7, and the limit drive 12 presses the processed part against the abutment plate 10 to position the part to be processed; then adjust the inclination angle of the jig plate 7 according to the required inclined hole parameters, and the horizontal drive 2 drives the hinge seat 31 to move toward the direction close to the external drilling equipment, thereby pushing the movable guide rod 35 to move upward along the guide groove 34 on the inclined bracket 32, and the connecting support frame 4 hinged to the movable guide rod 35 can drive the jig plate 7 to rotate upward with the hinge end 42 as the fulcrum until the angle required for processing the inclined hole is reached; finally, the external drilling equipment works to process the inclined hole on the part to be processed with the adjusted angle.

[0037] After all parts have been processed, the horizontal drive member 2 drives the movable guide rod 35 to move upward and tilt until the jig plate 7 moves to the waste collection area, and the waste accumulated on the jig plate 7 and the abutment plate 10 is cleaned into the waste collection box. At this time, the inclined jig plate 7 can also make the waste thereon automatically slide into the waste collection box under the action of gravity, thereby reducing the cleaning intensity of the staff.
