Description

Technical Field

[0001] This invention belongs to the field of automated processing, and specifically relates to a positioning and lifting fixture. Background Technology

[0002] In CNC automated production, sometimes it is necessary to process long workpieces multiple times, processing a small section at a time. Each time, the workpiece needs to be lifted up to allow the machining tool to process the next position. Therefore, the workpiece needs to be lifted up multiple times during the processing. This lifting operation is usually done manually, which results in high labor costs and low efficiency, seriously affecting the production efficiency of the workpiece. Summary of the Invention

[0003] To address the aforementioned problems, the present invention aims to provide a positioning and lifting fixture that can lift the workpiece while clamping and fixing it, facilitating automated processing of the workpiece by the processing equipment, thereby improving production efficiency and saving labor costs.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] This invention provides a positioning and lifting clamp, comprising:

[0006] Fixture module for positioning workpieces;

[0007] Lifting module used to raise workpieces;

[0008] The fixture module includes:

[0009] The fixture body used for limiting the workpiece;

[0010] A hydraulic clamping and positioning structure capable of clamping or releasing workpieces on the fixture body;

[0011] The fixture body and the lifting module are arranged vertically opposite each other, and the hydraulic clamping and positioning structure is arranged horizontally opposite to the fixture body.

[0012] In this application, the workpiece can be clamped and fixed by the combination of the fixture body and the hydraulic clamping and positioning structure. When the hydraulic clamping and positioning structure releases the workpiece, the workpiece can also be lifted by the lifting module, which facilitates the automated processing of the workpiece by the processing equipment, thereby improving production efficiency and saving labor costs.

[0013] Furthermore, the fixture body has through holes in the vertical direction for limiting the workpiece. The width of the through holes is slightly larger than the size of the workpiece, allowing the workpiece to move slightly horizontally within the through holes. Multiple through holes are provided, arranged horizontally in sequence. In this application, the multiple through holes arranged horizontally in sequence can accommodate multiple workpieces simultaneously, facilitating the processing device to process multiple workpieces at the same time, thereby improving workpiece processing efficiency. The width of the through holes is slightly larger than the width of the workpiece, preventing the workpiece from being jammed by the through holes and ensuring that the workpiece has a certain degree of freedom in the horizontal direction, facilitating the lifting module to lift the workpiece.

[0014] Furthermore, the hydraulic clamping and positioning structure includes:

[0015] Hydraulic clamping and positioning assembly;

[0016] And an oil supply assembly for supplying hydraulic fluid to the hydraulic clamping and positioning assembly;

[0017] The hydraulic clamping and positioning components are provided in two sets, which are respectively located on the left and right sides of the fixture body and connected by hydraulic oil circuits. This allows the two sets of hydraulic clamping and positioning components to clamp or release the workpiece on the fixture body simultaneously from the left and right sides, which has good coordination and thus improves stability.

[0018] Furthermore, the hydraulic clamping and positioning assembly includes:

[0019] Clamping and positioning base;

[0020] Clamping and positioning piston;

[0021] Clamping and positioning piston shaft;

[0022] The clamping and positioning base has a piston movable cavity, and the clamping and positioning piston is movably disposed in the piston movable cavity. One end of the clamping and positioning piston shaft is connected to the clamping and positioning piston, and the other end of the clamping and positioning piston shaft passes through the outside of the clamping and positioning base and is horizontally opposite to the fixture body.

[0023] The clamping and positioning base is also provided with a first oil inlet and a second oil inlet for the flow of hydraulic oil. The first oil inlet and the second oil inlet are both connected to the piston moving chamber, and the first oil inlet and the second oil inlet are respectively located on both sides of the clamping and positioning piston.

[0024] In this application, when the workpiece on the fixture body needs to be processed, hydraulic oil is injected into the piston moving chamber through the first oil inlet, pushing the clamping and positioning piston closer to the fixture body. The clamping and positioning piston shaft moves together with the clamping and positioning piston, cooperating with the fixture body to clamp and fix the workpiece on the fixture body in the horizontal direction. When the processing is completed and the workpiece needs to be lifted by the lifting module, hydraulic oil is injected into the piston moving chamber through the second oil inlet, pushing the clamping and positioning piston away from the fixture body. The clamping and positioning piston shaft moves together with the clamping and positioning piston, and the clamping and positioning piston shaft moves away from the workpiece, releasing the workpiece and ensuring that the workpiece has a certain degree of freedom, so that the lifting module can lift the workpiece.

[0025] Furthermore, the first oil inlets of the two sets of hydraulic clamping and positioning components are connected by pipelines, and the second oil inlets of the two sets of hydraulic clamping and positioning components are also connected by pipelines. This ensures that the clamping and positioning pistons of the two sets of hydraulic clamping and positioning components can move synchronously, clamping or releasing the workpiece from both sides simultaneously, exhibiting good coordination and consistency.

[0026] Furthermore, the hydraulic clamping and positioning assembly also includes a clamping and positioning guide bearing for guiding the movement of the clamping and positioning piston shaft, the clamping and positioning guide bearing being disposed within the clamping and positioning base.

[0027] Furthermore, an elastic buffer pad is provided between two adjacent through holes, and the two adjacent elastic buffer pads are clamped on both sides of a workpiece.

[0028] In this application, the elastic buffer pad is made of elastic plastic, rubber, foam and other materials. When the workpiece is clamped under the action of the hydraulic clamping and positioning component, the elastic buffer pad between the two workpieces will be compressed to ensure that the workpiece is clamped. When the hydraulic clamping and positioning component removes the pressure, the elastic buffer pad can push the workpiece to move slightly through elasticity to achieve reset, so that the workpiece returns to a state with a certain degree of freedom, thereby facilitating the lifting module to lift the workpiece.

[0029] Furthermore, the plurality of elastic buffer pads are connected by a rod, the two ends of which are fixed to the fixture body.

[0030] Furthermore, the oil supply assembly includes:

[0031] Oil supply shaft;

[0032] First oil inlet connector;

[0033] Second oil inlet connector;

[0034] The oil supply shaft has a first oil inlet channel and a second oil inlet channel. One end of the first oil inlet channel is connected to the first oil inlet connector, and the other end is connected to the first oil inlet. One end of the second oil inlet channel is connected to the second oil inlet connector, and the other end is connected to the second oil inlet.

[0035] In this application, hydraulic oil is supplied to the hydraulic clamping and positioning assembly through the cooperation of a first oil inlet connector, a second oil inlet connector, and an oil supply shaft.

[0036] Furthermore, the lifting module includes:

[0037] Lead screw motor;

[0038] Rotate the lead screw;

[0039] Lead screw base;

[0040] Lead screw bearing housing;

[0041] Workpiece support;

[0042] Lifting slide rail;

[0043] Lifting slider;

[0044] The output end of the lead screw motor is connected to the rotating lead screw. The upper end of the rotating lead screw is rotatably connected to the fixture body, and the lower end is rotatably connected to the lead screw base. The lead screw bearing seat is installed on the rotating lead screw, and the workpiece carrier is installed on the lead screw bearing seat. The lifting slider is connected to the workpiece carrier, and the lifting slider is slidably connected to the lifting slide rail.

[0045] In this application, when the lead screw motor is working, it can drive the lead screw bearing housing to move up and down on the rotating lead screw, thereby driving the workpiece bearing housing to move up and down, realizing the lifting of the workpiece on the workpiece bearing housing. During the lifting and lowering process of the workpiece bearing housing, the lifting slide rail and the lifting slider can be used for guidance, improving the stability of the lifting structure.

[0046] Furthermore, the positioning and lifting fixture also includes:

[0047] A rotating module used to drive the jig body to rotate;

[0048] A first rotating seat used to support one end of the fixture body;

[0049] A second rotating seat is used to support the other end of the fixture body;

[0050] A support base for supporting the second rotating seat;

[0051] The output end of the rotating module is connected to the first rotating seat, the first rotating seat is connected to one end of the fixture body, the second rotating seat is connected to the other end of the fixture body, and the second rotating seat is rotatably connected to the support base; the clamping and positioning bases of the two sets of hydraulic clamping and positioning components are respectively installed at both ends of the fixture body.

[0052] Two lifting slide rails are provided, and the two lifting slide rails are respectively installed on the first rotating seat and the second rotating seat.

[0053] In this application, the workpiece needs to have its machining angle adjusted during processing. This application sets up a rotating module that can work with the first rotating seat, the second rotating seat, and the support base to rotate the fixture body and the lifting module together to adjust the angle of the workpiece, making it easier to process the workpiece from different angles.

[0054] Furthermore, the oil supply shaft is installed through the support base, and the second rotating seat has a third oil inlet channel for connecting the first oil inlet channel and the first oil inlet port, and a fourth oil inlet channel for connecting the second oil inlet channel and the second oil inlet port. This allows hydraulic oil to be smoothly introduced into the clamping and positioning base without affecting rotation.

[0055] The beneficial effects of this invention are as follows: Compared with the prior art, this application can clamp and fix the workpiece by cooperating with the fixture body and the hydraulic clamping and positioning structure. When the hydraulic clamping and positioning structure releases the workpiece, the lifting module can also lift the workpiece, which facilitates the automated processing of the workpiece by the processing equipment, thereby improving production efficiency and saving labor costs.

[0067] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0068] To achieve the above objectives, the technical solution of the present invention is as follows:

[0069] See Figure 1-8 As shown, this embodiment provides a positioning and lifting fixture, including:

[0070] Fixture module 1 for positioning workpiece A;

[0071] Lifting module 2 is used to lift workpiece A;

[0072] The fixture module 1 includes:

[0073] Fixture body 11 for limiting workpiece A;

[0074] A hydraulic clamping and positioning structure 12 capable of clamping or releasing workpiece A on fixture body 11;

[0075] The fixture body 11 and the lifting module 2 are arranged vertically opposite each other, and the hydraulic clamping and positioning structure 12 is arranged horizontally opposite to the fixture body 11.

[0076] In this application, the workpiece A can be clamped and fixed by the fixture body 11 and the hydraulic clamping and positioning structure 12. When the hydraulic clamping and positioning structure 12 releases the workpiece A, the lifting module 2 can also lift the workpiece A, which facilitates the automated processing of the workpiece A for multiple processing operations, thereby improving production efficiency and saving labor costs.

[0077] Furthermore, the fixture body 11 has through holes 111 in the vertical direction for limiting the workpiece A. The width of the through holes 111 is slightly larger than the size of the workpiece A, allowing the workpiece A to move slightly horizontally within the through holes 111. Multiple through holes 111 are provided, arranged horizontally in sequence. In this application, 36 through holes 111 are provided, arranged horizontally in sequence, capable of accommodating 36 workpieces A simultaneously. This facilitates the processing device to process 36 workpieces A at the same time, thereby improving the processing efficiency of workpiece A. The width of the through holes 111 is slightly larger than the width of the workpiece A, preventing the workpiece A from being jammed by the through holes 111 and ensuring that the workpiece A has a certain degree of freedom in the horizontal direction, facilitating the lifting module 2 to lift the workpiece A.

[0078] Furthermore, the hydraulic clamping and positioning structure 12 includes:

[0079] Hydraulic clamping and positioning assembly 121;

[0080] And an oil supply assembly 122 for supplying hydraulic fluid to the hydraulic clamping and positioning assembly 121;

[0081] Two sets of hydraulic clamping and positioning components 121 are provided. The two sets of hydraulic clamping and positioning components 121 are respectively located on the left and right sides of the fixture body 11, and the hydraulic oil circuits are connected. This allows the two sets of hydraulic clamping and positioning components 121 to clamp or release the workpiece A on the fixture body 11 from the left and right sides simultaneously, which has good coordination and thus improves stability.

[0082] Furthermore, the hydraulic clamping and positioning assembly 121 includes:

[0083] Clamping and positioning base 1211;

[0084] Clamping and positioning piston 1212;

[0085] Clamping and positioning piston shaft 1213;

[0086] The clamping and positioning base 1211 has a piston movable cavity 1214, the clamping and positioning piston 1212 is movably disposed in the piston movable cavity 1214, one end of the clamping and positioning piston shaft 1213 is connected to the clamping and positioning piston 1212, and the other end of the clamping and positioning piston shaft 1213 passes through the outside of the clamping and positioning base 1211 and is horizontally opposite to the fixture body 11.

[0087] The clamping and positioning base 1211 is also provided with a first oil inlet 1215 and a second oil inlet 1216 for the flow of hydraulic oil. The first oil inlet 1215 and the second oil inlet 1216 are both connected to the piston moving chamber 1214, and the first oil inlet 1215 and the second oil inlet 1216 are respectively located on both sides of the clamping and positioning piston 1212.

[0088] In this application, when workpiece A on fixture body 11 needs to be processed, hydraulic oil is injected into piston movable chamber 1214 through first oil inlet 1215, pushing clamping and positioning piston 1212 closer to fixture body 11. Clamping and positioning piston shaft 1213 moves together with clamping and positioning piston 1212, cooperating with fixture body 11 to clamp and fix workpiece A on fixture body 11 in the horizontal direction. When the processing is completed and workpiece A needs to be lifted by lifting module 2, hydraulic oil is injected into piston movable chamber 1214 through second oil inlet 1216, pushing clamping and positioning piston 1212 away from fixture body 11. Clamping and positioning piston shaft 1213 moves together with clamping and positioning piston 1212, clamping and positioning piston shaft 1213 moves away from workpiece A, releasing workpiece A, ensuring that workpiece A has a certain degree of freedom, so that lifting module 2 can lift workpiece A.

[0089] Furthermore, the first oil inlets 1215 of the two sets of hydraulic clamping and positioning components 121 are connected by pipelines, and the second oil inlets 1216 of the two sets of hydraulic clamping and positioning components 121 are connected by pipelines. By opening oil ports on the side wall of the clamping and positioning base 1211 that are connected to the first oil inlets 1215 and the second oil inlets 1216, the oil ports on the clamping and positioning bases 1211 of the two sets of hydraulic clamping and positioning components 121 are connected by pipelines, thereby ensuring that the clamping and positioning pistons 1212 of the two sets of hydraulic clamping and positioning components 121 can move synchronously, clamping or releasing the workpiece A synchronously from the left and right sides, with good coordination and consistency.

[0090] Furthermore, the hydraulic clamping and positioning assembly 121 further includes a clamping and positioning guide bearing 1217 for guiding the movement of the clamping and positioning piston shaft 1213, the clamping and positioning guide bearing 1217 being disposed within the clamping and positioning base 1211.

[0091] Furthermore, an elastic buffer pad 112 is provided between two adjacent through holes 111, and the two adjacent elastic buffer pads 112 are clamped on both sides of a workpiece A.

[0092] In this application, the elastic buffer pad 112 is made of elastic plastic, rubber, foam and other materials. Since the 36 workpieces A are arranged horizontally in sequence, when the clamping and positioning piston 1212 of the hydraulic clamping and positioning assembly 121 pushes the workpiece A on the far side, it will push the remaining workpieces A in sequence through the workpiece A on the far side. The elastic buffer pad 112 between two adjacent workpieces A will be compressed to ensure that all workpieces A are in a clamped state. When the hydraulic clamping and positioning assembly 121 removes the pressure, the elastic buffer pad 112 can push the workpiece A slightly through elasticity to achieve reset, so that the workpiece A returns to a state with a certain degree of freedom, thereby facilitating the lifting module 2 to lift the workpiece A.

[0093] Furthermore, the plurality of elastic buffer pads 112 are connected through a rod 113, the two ends of which are fixed to the fixture body 11.

[0094] Furthermore, the oil supply assembly 122 includes:

[0095] Oil supply shaft 1221;

[0096] First oil inlet connector 1222;

[0097] Second oil inlet connector 1223;

[0098] The oil supply shaft 1221 has a first oil inlet channel 1224 and a second oil inlet channel 1225. One end of the first oil inlet channel 1224 is connected to the first oil inlet connector 1222, and the other end is connected to the first oil inlet 1215. One end of the second oil inlet channel 1225 is connected to the second oil inlet connector 1223, and the other end is connected to the second oil inlet 1216.

[0099] In this application, hydraulic oil is supplied to the hydraulic clamping and positioning assembly 121 through the cooperation of the first oil inlet connector 1222, the second oil inlet connector 1223, and the oil supply shaft 1221.

[0100] Furthermore, the lifting module 2 includes:

[0101] 21 lead screw motor;

[0102] Rotate lead screw 22;

[0103] Lead screw base 23;

[0104] Lead screw bearing housing 24;

[0105] Workpiece support 25;

[0106] Lifting slide rail 26;

[0107] Lifting slider 27;

[0108] The output end of the lead screw motor 21 is connected to the rotating lead screw 22. The upper end of the rotating lead screw 22 is rotatably connected to the fixture body 11, and the lower end is rotatably connected to the lead screw base 23. The lead screw bearing seat 24 is installed on the rotating lead screw 22. The workpiece bearing seat 25 is installed on the lead screw bearing seat 24. The lifting slider 27 is connected to the workpiece bearing seat 25, and the lifting slider 27 is slidably connected to the lifting slide rail 26.

[0109] In this application, when the lead screw motor 21 is working, it can drive the lead screw bearing seat 24 to move up and down on the rotating lead screw 22, thereby driving the workpiece bearing seat to move up and down, realizing the lifting of the workpiece on the workpiece bearing seat. During the lifting and lowering process of the workpiece bearing seat, the lifting slide rail 26 and the lifting slider 27 can be used for guidance, improving the stability of the lifting structure.

[0110] Furthermore, the positioning and lifting fixture also includes:

[0111] Rotation module 3 used to drive the jig body 11 to rotate;

[0112] A first rotating seat 4 is used to support one end of the jig body 11;

[0113] The second rotating seat 5 is used to support the other end of the jig body 11;

[0114] Support base 6 for supporting the second rotating seat 5;

[0115] The output end of the rotating module 3 is connected to the first rotating seat 4, the first rotating seat 4 is connected to one end of the fixture body 11, the second rotating seat 5 is connected to the other end of the fixture body 11, and the second rotating seat 5 is rotatably connected to the support base 6; the clamping and positioning bases 1211 of the two sets of hydraulic clamping and positioning components 121 are respectively installed at both ends of the fixture body 11.

[0116] Two lifting slide rails 26 are provided, and the two lifting slide rails 26 are respectively installed on the first rotating seat 4 and the second rotating seat 5.

[0117] In this application, the workpiece needs to have its processing angle adjusted during the processing. This application sets up a rotating module 3, which can work together with the first rotating seat 4, the second rotating seat 5, and the support base 6 to drive the fixture body 11 and the lifting module 2 to rotate together, thereby adjusting the angle of the workpiece and facilitating processing of the workpiece from different angles.

[0118] Furthermore, the oil supply shaft 1221 is installed through the support base 6. The second rotating seat 5 has a third oil inlet channel 51 connecting the first oil inlet channel 1224 and the first oil inlet 1215, and a fourth oil inlet channel 52 connecting the second oil inlet channel 1225 and the second oil inlet 1216. This allows hydraulic oil to be smoothly introduced into the clamping and positioning base 1211 without affecting rotation.

[0119] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention.
