Abstract
Description
Technical Field
[0001] The utility model relates to a workpiece fixing device, in particular to a clamping device for mechanical processing, belonging to the technical field of metal gasket production and processing devices. Background Art
[0002] Metal wound gasket is a widely used sealing gasket. It is the gasket with the best resilience among semi-metallic sealing gaskets. It is made of high-quality "V"-shaped or "W"-shaped metal strips and other alloy materials, graphite, asbestos, polytetrafluoroethylene, asbestos-free and other soft materials, which are alternately overlapped and spirally wound. In the production process of metal wound gasket, the soft material needs to be wound around the periphery of the metal ring. The metal ring needs to be fixed before winding. When the metal ring is fixed, it can be driven to rotate. The staff can realize the winding of the soft material while the metal ring rotates.
[0003] However, after traditional soft materials are wound a certain number of times, the operator needs to use a vernier caliper to measure the diameter of the gasket after winding, so as to control the diameter of the metal gasket after winding. Since the vernier caliper needs to be frequently taken and put down, the operation is less convenient, and the vernier caliper may be skewed when taken, which will cause certain measurement errors, resulting in lower measurement accuracy. Utility Model Content
[0004] The purpose of the utility model is to provide a mechanically processed clamping device to solve the above-mentioned problem, which can fix the gasket and also measure the diameter of the gasket after being wrapped with soft material. It is not only more convenient to measure, but also avoids measurement errors, thereby effectively improving the convenience of operation and the accuracy of measurement.
[0005] The utility model achieves the above-mentioned purpose through the following technical scheme: a mechanically processed clamping device, comprising a base, a plurality of mounting holes are provided on the base, a connecting column is fixedly connected to the base, a fixing structure is provided on the connecting column, a gasket is connected to the fixing structure, a measuring structure is provided on the connecting column, the measuring structure comprises a connecting ring and a guide rod, a connecting ring is rotatably connected to the connecting column, a guide rod is fixedly connected to the connecting ring, a sliding sleeve is slidably connected to the guide rod, a baffle is fixedly connected to the sliding sleeve, a knob is threadedly connected to the sliding sleeve, one end of the knob is in contact with the guide rod, a first connecting rod is fixedly connected to the guide rod, a second connecting rod is fixedly connected to the first connecting rod via bolts and nuts, and a mounting groove is provided on the second connecting rod.
[0006] Preferably, a T-shaped structure is formed between the connecting column and the base, and the plurality of mounting holes are distributed in a circular array about the center of the base.
[0007] Preferably, the cross-section of the knob is T-shaped, and one end of the knob is provided with a plurality of grooves distributed in a circular array.
[0008] Preferably, the first connecting rod and the second connecting rod are both provided with through grooves, and the cross section of the second connecting rod is an L-shaped structure.
[0009] Preferably, the baffle plate is perpendicular to the sliding sleeve, and the first connecting rod is perpendicular to the guide rod.
[0010] Preferably, the fixing structure includes a rotating rod and a screw, the connecting column is rotatably connected to the screw, the screw is threadedly connected to a connecting block, the connecting block is slidably connected to the connecting column, three sliders are fixedly connected to the connecting block, the slider is slidably connected to the connecting column, the connecting column is slidably connected to three sliding rods, two guide grooves are provided on the sliding rod, the slider is fixedly connected to a guide shaft, both ends of the guide shaft extend to the interior of two adjacent guide grooves and are slidably connected to the sliding rod, the sliding rod is fixedly connected to a resist plate, and the three resist plates are in contact with the inner side of the gasket.
[0011] Preferably, the cross-section of the abutment plate is a fan-shaped structure, and the three abutment plates are distributed in a circular array about the axis of the connecting column.
[0012] Preferably, the end of the screw is fixedly connected to a rotating rod, and the rotating rod passes through the screw and is perpendicular to the screw.
[0013] Preferably, the cross section of the slide rod is L-shaped, and the guide groove is inclined.
[0014] The beneficial effects of the utility model are as follows: when in use, the base can be fixed to the rotating shaft of the equipment through a plurality of mounting holes and bolts, and at the same time, the second connecting rod can be fixed to the equipment through the mounting groove and bolts. When the second connecting rod is fixed, the first connecting rod and the second connecting rod can be locked and fixed by bolts and nuts. At this time, the installation and fixation of the clamping device is completed, and then the gasket can be fixed by the fixing structure. When the gasket is fixed, the base can be driven to rotate by the rotating shaft, and the base drives the connecting column to rotate. The rotation of the connecting column will drive the gasket to rotate through the fixing structure. During the rotation of the gasket, the staff can wind the soft material. As the soft material is wound, the total diameter of the gasket and the soft material will become larger and larger. When the soft material is wound, the total diameter of the gasket and the soft material will become larger and larger. When the outer side of the baffle plate contacts with the baffle plate, the winding of the soft material can be stopped. Therefore, the baffle plate can be used to measure the total diameter of the gasket and the soft material during the winding of the soft material, avoiding the need to frequently move the vernier caliper for measurement, which not only improves the convenience of operation but also improves the accuracy of measurement. When the position of the baffle plate needs to be changed, it is only necessary to push the sliding sleeve to slide on the guide rod, and the movement of the sliding sleeve will drive the baffle plate to move together. When the position of the baffle plate is adjusted, the knob can be turned. When one side of the knob contacts the guide rod, the knob can be stopped. At this time, the sliding sleeve cannot slide on the guide rod, thereby completing the adjustment of the baffle plate position. Different diameters can be measured by adjusting the position of the baffle plate, thereby effectively improving the flexibility of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] As a technical optimization solution of the utility model, Figure 1 and Figure 2As shown, the first connecting rod 406 and the second connecting rod 407 are both provided with through grooves, the cross-section of the second connecting rod 407 is an L-shaped structure, the baffle 404 and the sliding sleeve 403 are perpendicular to each other, and the first connecting rod 406 and the guide rod 402 are perpendicular to each other, so the positions of the first connecting rod 406 and the second connecting rod 407 can be adjusted, thereby facilitating the installation between the clamping device and the equipment.
[0025] As a technical optimization solution of the utility model, Figure 1 , Figure 3 and Figure 4 As shown, the fixing structure 5 includes a rotating rod 501 and a screw rod 502, the connecting column 3 is rotatably connected with the screw rod 502, the screw rod 502 is threadedly connected with a connecting block 503, the connecting block 503 is slidably connected to the connecting column 3, three sliders 504 are fixedly connected to the connecting block 503, the sliders 504 are slidably connected to the connecting column 3, three sliding rods 506 are slidably connected to the connecting column 3, two guide grooves 507 are provided on the sliding rod 506, the slider 504 is fixedly connected with a guide shaft 505, both ends of the guide shaft 505 extend to the inside of two adjacent guide grooves 507 and are slidably connected to the sliding rod 506, and the sliding rod 506 is fixedly connected with a butt plate 508, the three butt plates 508 are in contact with the inner side of the gasket 6, the cross-section of the butt plate 508 is a fan-shaped structure, and the three butt plates 508 are distributed in a circular array about the axis of the connecting column 3, so that the gasket 6 can be fixed.
[0026] As a technical optimization solution of the utility model, Figure 1 and Figure 3 As shown, the end of the screw rod 502 is fixedly connected with a rotating rod 501 , and the rotating rod 501 passes through the screw rod 502 and is perpendicular to the screw rod 502 , so the screw rod 502 can be easily rotated by the rotating rod 501 .
[0027] As a technical optimization solution of the utility model, Figure 3 As shown, the cross section of the slide bar 506 is L-shaped, and the guide groove 507 is inclined, so that when the guide shaft 505 moves inside the guide groove 507, the slide bar 506 can slide on the connecting column 3.
[0028] When the utility model is in use, the base 1 can be fixed to the rotating shaft of the device through the multiple mounting holes 2 with bolts, and the second connecting rod 407 can be fixed to the device through the mounting groove 408 with bolts. When the second connecting rod 407 is fixed, the first connecting rod 406 and the second connecting rod 407 can be locked and fixed by bolts and nuts. At this time, the installation and fixation of the clamping device is completed, and then the gasket 6 can be sleeved on the outside of the three abutment plates 508, and then the screw 502 can be rotated by the rotating rod 501, and the screw 502 rotates the thread to drive the connecting block 503 to move. The movement of the connecting block 503 drives the three sliders 504 to move. The movement of the slider 504 drives the guide shaft 505 to move inside the guide groove 507. While the guide shaft 505 moves inside the guide groove 507, the slide bar 506 slides on the connecting column 3.

When the gasket 6 is fixed, the base 1 can be driven to rotate through the rotating shaft. The seat 1 drives the connecting column 3 to rotate, and the rotation of the connecting column 3 will cause the gasket 6 to rotate together. During the rotation of the gasket 6, the staff can wind the soft material. As the soft material is wound, the total diameter of the gasket 6 and the soft material will become larger and larger. When the outer side of the soft material and the baffle 404 conflict with each other, the winding of the soft material can be stopped. Therefore, the baffle 404 can be used to measure the total diameter of the gasket 6 and the soft material during the winding of the soft material, avoiding the need to frequently move the vernier caliper for measurement, which not only improves the convenience of operation but also improves the accuracy of measurement.

At this time, the sleeve 403 cannot slide on the guide rod 402, thereby completing the adjustment of the position of the baffle 404. By adjusting the position of the baffle 404, measurements of different diameters can be performed, thereby effectively improving the flexibility of operation.
