Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically to a tooling for processing metal products. Background Technology

[0002] As the manufacturing industry develops towards high-end, intelligent, and green development, the demand for metal product processing tooling in industries such as automobile manufacturing, aerospace, mechanical engineering, 3C electronics, and medical devices is constantly increasing. For example, intelligent tooling fixtures can automatically adjust the clamping force and position according to a preset program to adapt to the processing of workpieces of different specifications.

[0003] Existing tooling fixtures can only fix the workpieces being processed. However, some workpieces require double-sided or multi-sided processing, and need to be re-clamped and fixed when changing sides. Therefore, there is a need for a metal product processing tooling that can both clamp and fix the metal products and perform side-changing operations. Summary of the Invention

[0004] To address this issue, this utility model provides a metal product processing fixture that solves the problem of needing to re-clamp and fix some workpieces when processing them on two or more sides.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a metal product processing fixture, including a fixture base, two fixture auxiliary blocks fixedly mounted on the top of the fixture base, two fixture clamping assemblies mounted on the top of the fixture base, a protective cover connected between the two fixture clamping assemblies, a drive assembly connected inside the two fixture clamping assemblies, each fixture clamping assembly including a cylinder, the cylinder fixedly mounted on the top of the fixture auxiliary blocks, a connector fixedly connected to the output end of the cylinder, a spline shaft connected inside the connector, a spline sleeve fitted outside the spline shaft, a support frame fitted outside the spline sleeve, a fixture clamping unit connected to one end of the spline shaft, and a worm gear reducer motor fixedly mounted on the top of the fixture base, a drive shaft fixedly connected to the output end of the worm gear reducer motor, and a drive unit fitted outside the spline sleeve and the drive shaft.

[0006] Preferably, the tooling fixture unit includes a fixed frame, which is fixedly connected to one end of a spline shaft. A through groove is provided inside the fixed frame, and a bidirectional lead screw is inserted into the through groove. A knob is fixedly provided at both ends of the bidirectional lead screw, and two clamping plates are sleeved on the outside of the bidirectional lead screw.

[0007] Preferably, the bidirectional lead screw passes through both sides of the through groove and is connected to both sides of the through groove via bearings. The threads at both ends of the bidirectional lead screw have opposite directions. The bidirectional lead screw passes through two clamping plates and is connected to the two clamping plates via threads. One end of each of the two clamping plates extends into the through groove and is slidably connected to the through groove.

[0008] Preferably, one end of the spline shaft extends into the connector and is connected to the connector via a bearing, and the spline shaft passes through the spline sleeve and is connected to the spline sleeve via a spline pair.

[0009] Preferably, the spline sleeve passes through both sides of the support frame and is connected to both sides of the support frame via bearings, and the bottom of the support frame is fixedly connected to the top of the tooling base.

[0010] Preferably, the drive shaft passes through both support frames and is connected to both support frames via bearings.

[0011] Preferably, the drive unit includes a toothed pulley one, a synchronous toothed belt, and a toothed pulley two. The toothed pulley one is fixedly sleeved on the outside of the drive shaft, and the toothed pulley two is fixedly sleeved on the outside of the spline sleeve. Both the toothed pulley one and the toothed pulley two mesh with the synchronous toothed belt, and the toothed pulley one and the toothed pulley two are driven connected by the synchronous toothed belt.

[0012] Preferably, the protective cover is fixedly connected to two support frames at both ends, and the protective cover is sleeved on the outside of the drive shaft.

[0013] The present invention has the following advantages:

[0014] The cylinder operates to move the output end, which in turn moves the connector. The movement of the connector moves the spline shaft along the spline sleeve, causing the tooling fixture unit to move. This controls the distance between the two tooling fixture units, allowing them to accommodate various metal product sizes. The knob is rotated to rotate the bidirectional lead screw, which in turn moves the two clamping plates relative to each other, thus controlling the clamping plates to hold and fix the metal product.

[0015] The rotation of the drive shaft drives the toothed pulley 1 in the tooling fixture assembly on both sides to rotate. The rotation of toothed pulley 1 drives toothed pulley 2 to rotate through the synchronous toothed belt. The rotation of toothed pulley 2 drives the spline sleeve to rotate. The rotation of the spline sleeve drives the spline shaft to rotate, which in turn drives the tooling fixture unit to rotate, thereby causing the clamped metal product to rotate and flip, achieving the purpose of not needing to clamp and adjust the machining surface again.

[0023] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] See attached document Figure 1 - Appendix Figure 4 This utility model provides a metal product processing fixture, including a fixture base 1, two fixture auxiliary blocks 2 fixedly mounted on the top of the fixture base 1, two fixture clamping assemblies 3 mounted on the top of the fixture base 1, a protective cover 4 connected between the two fixture clamping assemblies 3, and a drive assembly 5 connected inside the two fixture clamping assemblies 3. Each fixture clamping assembly 3 includes a cylinder 31, which is fixedly mounted on the top of the fixture auxiliary blocks 2. A connector 32 is fixedly connected to the output end of the cylinder 31. A spline shaft 33 is connected inside the connector 32. A spline sleeve 34 is fitted outside the spline shaft 33. A support frame 35 is fitted outside the spline sleeve 34. A fixture clamping unit 36 ​​is connected to one end of the spline shaft 33. The drive assembly 5 includes a worm gear reducer motor 51, which is fixedly mounted on the top of the fixture base 1. A transmission shaft 52 is fixedly connected to the output end of the worm gear reducer motor 51. A drive unit is fitted outside the spline sleeve 34 and the transmission shaft 52.

[0025] In this implementation scheme, in order to achieve both clamping and fixing of metal products and flipping of metal products while clamped, the distance between the two tooling fixture units 36 is first adjusted according to the size of the metal product. The cylinder 31 is then activated, and the operation of the cylinder 31 causes the output end to move, which in turn moves the connector 32. The movement of the connector 32 causes the spline shaft 33 to move along the spline sleeve 34, thereby moving the tooling fixture unit 36. This controls the distance between the two tooling fixture units 36 and clamps and fixes the metal product through the tooling fixture unit 36. When it is necessary to flip the metal product clamped by the tooling fixture unit 36, the worm gear reducer motor 51 is activated. The rotation of the worm gear reducer motor 51 drives the transmission shaft 52 to rotate. The rotation of the transmission shaft 52 drives the spline sleeve 34 to rotate through the drive unit. The rotation of the spline sleeve 34 drives the spline shaft 33 to rotate, which in turn drives the tooling fixture unit 36 ​​to rotate, thereby causing the clamped metal product to rotate and flip, achieving the purpose of not needing to clamp and adjust the processing surface again.

[0026] To achieve the purpose of clamping metal products by the tooling fixture unit 36, the device adopts the following technical solution: The tooling fixture unit 36 ​​includes a fixed frame 361, which is fixedly connected to one end of the spline shaft 33. A through groove 362 is opened inside the fixed frame 361, and a bidirectional lead screw 364 is inserted into the through groove 362. A knob 363 is fixedly provided at both ends of the bidirectional lead screw 364. Two clamping plates 365 are sleeved on the outside of the bidirectional lead screw 364. The bidirectional lead screw 364 passes through the two side walls of the through groove 362 and is connected to the two side walls of the through groove 362 through bearings. The threads at both ends of the bidirectional lead screw 364 have opposite directions. The bidirectional lead screw 364 passes through the two clamping plates 365 and is connected to the two clamping plates 365 through threads. One end of each clamping plate 365 extends into the through groove 362 and is slidably connected to the through groove 362. One end of the spline shaft 33 extends into the through groove 362. The connector 32 is connected to the connector head 32 via a bearing. The spline shaft 33 passes through the spline sleeve 34 and is connected to the spline sleeve 34 via a spline pair. The spline sleeve 34 passes through the two side walls of the support frame 35 and is connected to the two side walls of the support frame 35 via bearings. The bottom of the support frame 35 is fixedly connected to the top of the tooling base 1. The operation of the cylinder 31 causes the output end to move, which in turn moves the connector head 32. The movement of the connector head 32 causes the spline shaft 33 to move along the spline sleeve 34, which in turn moves the tooling fixture unit 36, thereby controlling the distance between the two tooling fixture units 36. When it is necessary to clamp and fix the metal product through the tooling fixture unit 36, the knob 363 is rotated. The rotation of the knob 363 causes the bidirectional lead screw 364 to rotate. The rotation of the bidirectional lead screw 364 causes the two clamping plates 365 to move relative to each other, thereby controlling the two clamping plates 365 to clamp and fix the metal product.

[0027] To achieve the purpose of flipping the metal product held by the tooling fixture unit 36, this device adopts the following technical solution: the drive shaft 52 passes through two support frames 35 and is connected to both support frames 35 via bearings; the drive unit includes a toothed pulley 37, a synchronous toothed belt 38, and a toothed pulley 39; the toothed pulley 37 is fixedly sleeved outside the drive shaft 52, and the toothed pulley 39 is fixedly sleeved outside the spline sleeve 34; both the toothed pulley 37 and the toothed pulley 39 mesh with the synchronous toothed belt 38; the toothed pulley 37 and the toothed pulley 39 are driven and connected by the synchronous toothed belt 38; and the protective cover 4 is fixedly connected to the two support frames 35 at both ends. Next, the protective cover 4 is fitted outside the drive shaft 52. When it is necessary to flip the metal product held by the tooling fixture unit 36, the worm gear reducer motor 51 is started. The rotation of the worm gear reducer motor 51 drives the drive shaft 52 to rotate. The rotation of the drive shaft 52 drives the toothed pulley 37 in the tooling fixture assembly 3 on both sides to rotate. The rotation of the toothed pulley 37 drives the toothed pulley 39 to rotate through the synchronous toothed belt 38. The rotation of the toothed pulley 39 drives the spline sleeve 34 to rotate. The rotation of the spline sleeve 34 drives the spline shaft 33 to rotate, which in turn drives the tooling fixture unit 36 ​​to rotate, thereby causing the clamped metal product to rotate and flip, achieving the purpose of not needing to clamp and adjust the processing surface again.

[0028] The usage process of this utility model is as follows: When using this utility model, connect an external power source. When clamping metal, first adjust the distance between the two tooling fixture units 36 according to the size of the metal product. Start the cylinder 31. The operation of the cylinder 31 causes the output end to move, which in turn moves the connector 32. The movement of the connector 32 causes the spline shaft 33 to move along the spline sleeve 34, thereby moving the tooling fixture unit 36 ​​and controlling the distance between the two tooling fixture units 36. When it is necessary to clamp and fix the metal product through the tooling fixture unit 36, rotate the knob 363. The rotation of the knob 363 causes the bidirectional lead screw 364 to rotate, which in turn causes the two clamping plates 365 to move relative to each other. This controls the two clamping plates 365 to clamp and fix the metal product. When it is necessary to flip the metal product clamped by the tooling fixture unit 36, the worm gear reducer motor 51 is started. The rotation of the worm gear reducer motor 51 drives the transmission shaft 52 to rotate. The rotation of the transmission shaft 52 drives the toothed pulley 37 in the tooling fixture assembly 3 on both sides to rotate. The rotation of the toothed pulley 37 drives the toothed pulley 39 to rotate through the synchronous toothed belt 38. The rotation of the toothed pulley 39 drives the spline sleeve 34 to rotate. The rotation of the spline sleeve 34 drives the spline shaft 33 to rotate, which in turn drives the tooling fixture unit 36 ​​to rotate, thereby causing the clamped metal product to rotate and flip, achieving the purpose of not needing to clamp and adjust the processing surface again.

[0029] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
