Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a fixed tooling for workpiece processing. Background Art

[0002] In the mechanical manufacturing and processing industries, fixtures (also known as jigs or fixtures) are important tools used to secure workpieces and keep them stable during processing. The main purpose of using fixtures is to ensure processing accuracy, improve production efficiency, and ensure operator safety.

[0003] In the prior art, after the workpiece is placed on the fixed fixture for processing, burrs will remain on the surface of the workpiece on the fixed fixture. At this time, the staff usually needs to use an air gun to clean the burrs on the surface. However, due to the staff's carelessness and the desire to speed up the process, the burrs are often not completely removed. This will cause the new workpiece to be placed unevenly on the fixed fixture during the next processing, resulting in errors in the processed workpiece. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a fixed tool for workpiece processing in view of the current status of the existing technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is: to propose a fixed tool for workpiece processing, comprising:

[0006] Workbench;

[0007] a first fixing assembly disposed on the workbench, the first fixing assembly comprising a first fixing member and a detection member, the first fixing member movably abutting against the workpiece to fix the workpiece, the detection member being used to detect whether the first fixing member has moved to a preset position;

[0008] The second fixing component is located on one side of the first fixing component. The second fixing component has a second fixing part and a lifting part. The second fixing part is movably inserted on the workpiece and movably abuts against the workpiece to provide fixation for the workpiece. The lifting part can lift the workpiece when the workpiece is placed on the workbench to provide support for the workpiece.

[0009] In the above-mentioned fixed tooling for workpiece processing, a support seat is further provided on the workbench, and the support seat is used to provide support for the workpiece.

[0010] In the above-mentioned fixed tooling for workpiece processing, the support seat is further provided with a support block and a positioning protrusion provided on the support block, the first fixed blocks are provided on both sides of the support block, and the positioning protrusion is used to provide positioning for the workpiece.

[0011] In the above-mentioned fixing fixture for workpiece processing, a positioning groove is further provided on the support seat, and the second fixing member and the lifting member are both movably inserted into the positioning groove.

[0012] In the above-mentioned fixing fixture for workpiece processing, the first fixing assembly further includes:

[0013] A first driving member, wherein the first driving member is provided on both sides of the support seat, the first driving member is connected to the first fixing member, and the first driving member is used to drive the first fixing member to rotate;

[0014] A connecting block is provided on each of the first driving members. One side of the first fixing member is connected to the output end of the first driving member, and the other side is hinged to the connecting block.

[0015] In the above-mentioned fixing fixture for workpiece processing, the second fixing member has an undercut structure, and the undercut structure movably abuts against the workpiece.

[0016] In the above-mentioned fixing tool for workpiece processing, the second fixing assembly also includes a second driving member, which is arranged below the support seat, and the second fixing member passes through the support seat and is connected to the output end of the second driving member, and the second driving member is used to drive the second fixing member to rise and fall.

[0017] In the above-mentioned fixed tooling for workpiece processing, the second fixed component also includes a third driving member, the third driving member is provided below both sides of the support seat, the output end of the third driving member is provided with the lifting member, and the third driving member is used to drive the lifting member to rise and fall.

[0018] Compared with the prior art, the advantage of the present invention is that, through the arrangement of the detection member and the lifting member, when a workpiece is placed at the position of the first fixing assembly, if the burrs on the surface of the workpiece have been cleaned, the first fixing member will be pressed against the workpiece at a preset position; if the burrs on the surface of the workpiece are not completely cleaned, the position where the first fixing member is pressed against the workpiece will deviate from the preset position, and this displacement change will be detected by the detection member. Once it is detected that the displacement of the first fixing member deviates from the preset position, the detection member will sound an alarm, prompting the staff to clean the burrs on the surface of the workpiece; the workpiece placed at the position of the second fixing assembly is driven to rise to the preset position by the lifting member, and then the second fixing member fixes the workpiece under the drive of the second fixing assembly. Since the lifting member drives the workpiece to lift, there will be no direct surface-to-surface contact between the workpiece and the workbench. Therefore, even if there are burrs on the surface of the workpiece that have not been cleaned, the fixed position of the workpiece on the workbench will not be uneven. Through the above steps, the fixing fixture in this scheme can avoid errors in the processed workpiece caused by uneven placement of the workpiece on the fixing fixture when fixing the workpiece.

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figures 1 to 4As shown, the utility model is a fixed tool for workpiece processing, comprising: a workbench 1; a first fixing component 2, which is arranged on the workbench 1, the first fixing component 2 has a first fixing part 3 and a detection part 4, the first fixing part 3 is movably abutted against the workpiece for fixing the workpiece, and the detection part 4 is used to detect whether the first fixing part 3 is moved to a preset position; a second fixing component 5, which is located on one side of the first fixing component 2, the second fixing component 5 has a second fixing part 6 and a lifting part 7, the second fixing part 6 is movably inserted on the workpiece and movably abutted against the workpiece for providing fixation for the workpiece, and the lifting part 7 can lift the workpiece because the workpiece is placed on the workbench 1, so as to provide support for the workpiece.

[0026] During the actual production operation, the workpiece is first placed at two key positions on the workbench 1: the positions of the first fixing component 2 and the second fixing component 5; these two positions are used for different fixing operations respectively to ensure the stability of the workpiece during the processing. At this time, the workpiece placed at the position of the first fixing component 2 is abutted against the first fixing component 3 to achieve a fixing effect; if the surface on which the workpiece is placed has been thoroughly cleaned, the first fixing component 3 can fit tightly with the workpiece at the preset position to provide a stable support. However, if the burrs on the surface on which the workpiece is placed are not completely cleaned, the contact position between the first fixing component 3 and the workpiece will be offset, and the expected fixing effect cannot be achieved. This tiny displacement change will be accurately captured by the detection component 4 and immediately fed back to the control system. Once it is detected that the displacement of the first fixing component 3 deviates from the preset position, the detection component 4 will trigger an alarm to remind the on-site staff to clean the burrs on the surface on which the workpiece is placed in time to ensure that the workpiece can maintain an ideal fixed state in the subsequent processing. Among them, the detection component 4 is preferably a displacement sensor.

[0027] For the workpiece placed at the position of the second fixing component 5, the lifting member 7 will lift it smoothly to the preset height. After the workpiece reaches the correct position, the second fixing member 6 is driven by the second fixing component 5 to finally fix the workpiece. The key to this design is that due to the action of the lifting member 7, direct surface-to-surface contact between the workpiece and the placement surface is avoided. Such a design not only protects the workpiece from potential scratches or damage, but also even if there are uncleaned burrs on the workbench 1, it will not affect the fixing effect of the workpiece. The workpiece can still maintain a flat placement state, thereby ensuring that the processing accuracy is not affected.

[0028] Through the above series of carefully designed operating steps, the fixed tooling in this solution can significantly improve the accuracy and reliability of workpiece fixation. It can effectively avoid processing errors caused by uneven placement of the workpiece on the fixed tooling, thereby ensuring that the quality of the final processed workpiece meets high standards.

[0029] In order to provide support for the workpiece, a support base 8 is further provided on the workbench 1 to ensure that the workpiece remains stable during the processing.

[0030] Furthermore, the support seat 8 is provided with a support block 9 and a positioning protrusion 10 provided on the support block 9. A first fixing member 3 is provided on both sides of the support block 9. When the workpiece is placed on the support block 9, the positioning protrusion 10 is used to provide positioning for the workpiece. Subsequently, the first fixing member 3 fixes the workpiece on the support block 9. If the burrs on the surface of the support block 9 are completely cleaned, the first fixing member 3 can fit tightly with the workpiece at the preset position to provide stable support. However, if the burrs on the surface of the support block 9 are not completely cleaned, the contact position between the first fixing member 3 and the workpiece will be offset. This displacement change will be accurately captured by the detection member 4, and an alarm will be issued to remind the staff to clean the burrs on the support block 9 in time to ensure that the workpiece can maintain an ideal fixed state in the subsequent processing.

[0031] Furthermore, a positioning groove 11 is provided on the support seat 8, and the second fixing member 6 and the lifting member 7 are movably inserted in the positioning groove 11. When the workpiece is placed on the positioning groove 11, the second fixing component 5 is immediately started to drive the lifting member 7 to lift the workpiece. When the lifting member 7 drives the workpiece to rise to the preset position, the second fixing member 6 fixes the workpiece. At this time, the workpiece is lifted by the lifting member 7, and there will be no surface-to-surface contact between the workpiece and the positioning groove 11. Even if the burrs in the positioning groove 11 are not completely cleaned, it will not affect the fixation of the workpiece.

[0032] Specifically, the first fixing assembly 2 also includes: a first driving member 12, a first driving member 12 is provided on both sides of the support seat 8, each first driving member 12 is connected to a first fixing member 3, and the first driving member 12 is used to drive the first fixing member 3 to rotate; a connecting block 13, each first driving member 12 is provided with a connecting block 13, one side of the first fixing member 3 is connected to the output end of the first driving member 12, and the other side is hinged on the connecting block 13; when the workpiece is placed on the support block 9, the first driving members 12 on both sides are immediately started, driving the first fixing member 3 thereon to rotate, so that the first fixing member 3 approaches the workpiece until it is tightly pressed against the workpiece, so that the workpiece is stably fixed on the support block 9, if the burrs on the surface of the support block 9 are completely cleaned, the first driving member 12 drives the first fixing member 3 to rotate to a preset position; if the burrs on the surface of the support block 9 are not completely cleaned, the position where the first driving member 12 drives the first fixing member 3 to rotate will deviate from the preset position, and the first driving member 12 can be a cylinder, a cylinder or a motor.

[0033] Specifically, the second fixing member 6 has an undercut structure 14 , and the undercut structure 14 movably abuts against the workpiece.

[0034] Furthermore, the second fixing assembly 5 also includes a second driving member 15, which is arranged below the support seat 8. The second fixing member 6 passes through the support seat 8 and is connected to the output end of the second driving member 15. The second driving member 15 is used to drive the second fixing member 6 to rise and fall. The second driving member 15 can be an oil cylinder, an air cylinder or a motor.

[0035] Furthermore, the second fixing component 5 also includes a third driving member 16. The third driving member 16 is arranged below both sides of the support seat 8. The output end of the third driving member 16 is provided with a lifting member 7. The third driving member 16 is used to drive the lifting member 7 to rise and fall. The third driving member 16 can be an oil cylinder or a motor.

[0036] During operation, the workpiece passes through the undercut structure 14 on the second fixing member 6 and is placed in the positioning groove 11. Subsequently, the third driving members 16 on both sides of the support seat 8 are started synchronously, driving the lifting member 7 thereon to rise in the positioning groove 11, and the lifting member 7 drives the workpiece in the positioning groove 11 to rise synchronously. When the workpiece is lifted to the preset position, the third driving member 16 stops driving. At the same time, the second driving member 15 is started, driving the second fixing member 6 to descend. At this time, the undercut structure 14 on the second fixing member 6 approaches the workpiece until it is tightly pressed against the workpiece, and the workpiece is stably fixed.
