To increase the stability of the workpiece during movement, pulleys or balls can be installed at the bottom of the base 21 so that the entire device can move smoothly.

[0035] Refer to Figure 1 and Figure 2 Specifically, the first positioning seat 31 is in an "L" shape, that is, it includes a horizontal part located below and a vertical part extending vertically upward. Its first positioning groove 311 is opened on the vertical part; the locking member 32 includes a locking handle 321 and a gasket 322. External threads are provided on the side wall of the pull rod 211, and a threaded groove for the pull rod 211 to pass through and threadedly connect with the pull rod 211 is opened on the locking handle 321, and the threaded groove extends through to both end faces of the locking handle 321; during use, first pass the pull rod 211 through the first positioning groove 311, then sleeved the gasket 322 on the pull rod 211, then sleeve the locking handle 321 on the pull rod 211, and rotate the locking handle 321 so that the pull rod 211 drives the base 21 and the workpiece to slide in the direction of the first positioning seat 31; to facilitate positioning the position of the workpiece, a cushion block 212 is also fixed on the side wall of the base 21, and the pull rod 211 passes through the cushion block 212. When the side wall of the cushion block 212 driven by the locking handle 321 abuts against the side wall of the first positioning seat 31, the workpiece is fixed to the preset position.

[0036] Refer to Figure 1 and Figure 2In this embodiment, the first mounting seat 33 can be adjusted and fixed on the mounting base plate 1, and can adjust the position along the length and width direction of the mounting base plate 1. Specifically, the first positioning assembly 3 also includes a first mounting seat 33 and a first bolt 34, wherein the first mounting seat 33 is a rectangular seat and is arranged on the mounting base plate 1, the lower surface of the first mounting seat 33 is provided with a first mounting groove 331 for the horizontal part of the first positioning seat 31 to pass through, the upper surface of the first mounting seat 33 is provided with a first waist-shaped hole 332, the first waist-shaped hole 332 extends along the length direction of the mounting base plate 1, and the upper surface of the horizontal part of the first positioning seat 31 is provided with a threaded hole for the first bolt 34 to be threadedly connected, so that the first bolt 34 is passed through the first waist-shaped hole 332 and is threadedly connected with the first positioning seat 31, so that the head of the first bolt 34 is pressed against the upper surface of the first mounting seat 33, and the first positioning seat 31 can be fixed on the first mounting seat 33, and at the same time, the position of the first positioning seat 31 can be adjusted along the length direction of the mounting base plate 1 by adjusting the position of the first bolt 34 passing through the first waist-shaped hole 332.

[0037] Furthermore, the first positioning assembly 3 also includes a second bolt 35, and the first mounting seat 33 is also provided with a second waist-shaped hole 333 for the second bolt 35 to pass through, wherein the second waist-shaped hole 333 extends along the width direction of the mounting base plate 1, and the second bolt 35 can pass through the second waist-shaped hole 333 and be threadedly connected with the mounting base plate 1, thereby locking the first mounting seat 33 on the mounting base plate 1; at the same time, by adjusting the position of the second bolt 35 passing through the second waist-shaped hole 333, the position of the first positioning seat 31 can be adjusted along the width direction of the mounting base plate 1.

[0038] Reference Figure 1 and Figure 3 In this embodiment, in order to further improve the accuracy and stability of positioning, the fixing device also includes a second positioning assembly 4, which includes a second positioning seat 41 and a lift 42. The lift 42 includes a fixed plate 422 fixed to the mounting base plate 1 by bolts, a lift plate 421 sliding up and down above the fixed plate 422, and a driving member 423 driving the lift plate 421 to move up and down. The second positioning seat 41 is also an "L"-shaped structure, and a second positioning groove 411 is provided on the upper surface of its vertical part. A copper tube is fixed on the workpiece, and the axis of the copper tube is parallel to the axis of the connecting rod. When the connecting rod is inserted into the first positioning groove 311, the copper tube on the workpiece can be inserted into the second positioning groove 411, further limiting the movement of the workpiece and improving the stability of the workpiece; and the horizontal part of the second positioning seat 41 is fixed to the mounting side plate. At the same time, due to the different heights of the copper tube positions between different workpieces, the lift 42 can ensure that the copper tubes on different workpieces can be inserted into the second positioning groove 411.

[0039] Reference Figure 3 and Figure 4, in an optional embodiment, in order to install the second positioning seat 41, a side plate may be fixed on the side wall of the lifting plate 421, and the horizontal part of the second positioning seat 41 may be fixed to the side plate by means of bolt-nut cooperation. And in order to facilitate the adjustment of the position of the second positioning seat 41, a waist-shaped groove may be opened on the side plate along the width direction of the mounting base plate 1, and a waist-shaped groove may be opened on the horizontal part of the second positioning seat 41 along the length direction of the mounting base plate 1. The bolts are sequentially passed through the second positioning seat 41 and the side plate and locked by nuts, and then the second positioning seat 41 can be fixed well.

[0040] Refer to Figure 3 and Figure 4 , further, the second positioning assembly 4 further includes a positioning rod 43 provided on the lifting plate 421. A positioning hole 431 is opened on the end surface of one end of the positioning rod 43 facing the second positioning seat 41. When the copper tube passes through the second positioning groove 411, it can be inserted into the positioning hole 431, and the copper tube is a stepped tube, that is, the end far from the workpiece has an inner tube with a smaller diameter. When the inner tube is inserted into the positioning hole 431 and the outer tube with a larger diameter abuts against the side wall of the positioning rod 43, the workpiece moves to a predetermined position. At this time, correspondingly, the side wall of the cushion block 212 abuts tightly against the side wall of the first positioning seat 31.

[0041] To facilitate the installation of the positioning rod 43, a support 5 is fixed on the lifting plate 421. A positioning block 432 is coaxially sleeved on the outer side wall of the positioning rod 43. The upper and lower surfaces of the positioning block 432 are horizontal planes. A clamping groove for the positioning block 432 to be clamped is opened on the support 5, and a third bolt 51 is further provided on the support 5. When the positioning block 432 is clamped in the clamping groove, the third bolt 51 is threadedly connected through the upper part of the support 5 from top to bottom, and the end surface of the third bolt 51 abuts against the positioning block 432. By tightening the third bolt 51, the positioning block 432 and the positioning rod 43 can be clamped tightly on the support 5.

[0042] Refer to Figure 3 and Figure 4 , in this embodiment, the driving member 423 adopts a scissor lift structure and drives the sliding end to approach the fixed end by rotating the screw rod, so that the upper lifting plate 421 moves up and down to achieve the purpose of moving the lifting plate 421 up and down. This structure is a prior art and will not be elaborated here. In other embodiments, the driving member 423 may also adopt a structure such as a cylinder. The cylinder body is fixed on the fixed plate 422, and the telescopic shaft of the cylinder is fixed to the lifting plate 421, and then the lifting plate 421 can be moved up and down.

[0043] The implementation principle of a workpiece evacuation and fixing device according to an embodiment of the present application is as follows: Before fixing the workpiece, first adjust the position of the first positioning seat 31 by adjusting the first bolt 34 and the second bolt 35 according to the workpiece to be fixed; then adjust the position of the second positioning seat 41 through the elevator 42; when fixing the workpiece, first fix the workpiece on the base 21 through the clamping assembly 22, then place the base 21 on the mounting base plate 1, and then slide the base 21 in the direction of the first positioning seat 31, so that the pull rod 211 on the base 21 passes through the first positioning groove 311, and at the same time, the copper tube on the workpiece correspondingly passes through the second positioning groove 411 and is aligned and inserted into the positioning hole 431 on the positioning rod 43; then sequentially sleeved the gasket 322 and the locking handle 321 on the end of the pull rod 211, and rotate the locking handle 321 to drive the pull rod 211 to move in the direction away from the base 21, and at the same time drive the base 21 and the workpiece to move. When the cushion block 212 abuts against the side wall of the first positioning seat 31, the positioning before workpiece evacuation is completed.
