[0039] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0040] like Figure 1 The existing workpiece positioning and machining fixture mainly includes a fixture base 1 with a straight strip structure. Several positioning cavities are evenly opened on the fixture base 1 along the left and right direction. In each positioning cavity, a workpiece 3 and a clamping component 2 are installed from left to right. The clamping component is generally an OK clamp, etc. However, the OK clamp requires frequent tightening of bolts during operation, which is cumbersome and requires more processing time.

[0041] The first embodiment of this utility model:

[0042] like Figure 3 In this embodiment, a positioning and machining fixture for a straight strip-shaped workpiece has several positioning cavities evenly provided on the fixture base 1 of the straight strip-shaped structure along the left and right directions. The positioning cavity is formed by two spacer blocks 7 on the left and right sides.

[0043] like Figure 4 In each positioning cavity, a workpiece mounting groove 8 and a clamping component mounting groove 9 are arranged sequentially from left to right. The workpiece mounting groove 8 is slightly lower than the clamping component mounting groove 9, so that a stepped structure is formed between the workpiece mounting groove 8 and the clamping component mounting groove 9, which facilitates the separation of the workpiece 3 from the clamping component 2.

[0044] The workpiece 3 to be processed is placed in the workpiece mounting slot 8, and a positioning block 12 for positioning the workpiece 3 is installed in the workpiece mounting slot 8.

[0045] The positioning block 12 is detachably installed in the workpiece mounting groove 8. A positioning groove 11, which is a countersunk hole structure, is provided within the workpiece mounting groove 8. The positioning post at the top of the positioning block 12 is installed at the top of the positioning groove 11, and the base plate at the bottom of the positioning block 12 is installed at the bottom of the positioning groove 11. Both are then secured together with bolts within the positioning groove 11. The detachable structure of the positioning block 12 facilitates the replacement of different positioning blocks 12, thus enabling convenient positioning of various workpieces 3.

[0046] The clamping member 2 in this embodiment is as follows: Figures 5-10 As shown:

[0047] The clamping component 2 mainly includes a fixing component 13, a driving component 14, and a clamping block component 15.

[0048] like Figures 7-8 As shown, the fixing component 13 mainly includes a fixing base 18, which can be fixedly installed in the clamping component mounting groove 9 by bolts, serving as the basic support structure of the clamping component 2.

[0049] A tapered groove 19 is provided in the middle of the fixed base 18. A transverse movable cavity 20 is provided in the fixed base 18 on the left side of the tapered groove 19 and is connected to the tapered groove 19 on the right side. A transverse through hole 21 is provided on the left side of the transverse movable cavity 20.

[0050] like Figure 8 A longitudinal movable cavity 22 is provided on both sides of the first diagonal of the fixed base 18, and a longitudinal through hole 23 is provided on the top of the longitudinal movable cavity 22 to communicate with the longitudinal movable cavity 22 below.

[0051] like Figure 9The drive assembly 14 mainly includes a drive top plate 24, and a handle 25 is installed at the top center of the drive top plate 24, which facilitates the operation of the entire drive assembly 14.

[0052] A conical block 26 adapted to the conical groove 19 is provided at the bottom center of the drive top plate 24. The conical block 26 can be sequentially embedded into the conical groove 19 below from top to bottom.

[0053] Furthermore, a longitudinal movable rod 27 is provided at the bottom of the drive top plate 24 directly above the longitudinal movable cavity 22. The longitudinal movable rod 27 is integrally formed with the drive top plate 24. The longitudinal movable rod 27 can pass through the longitudinal through hole 23 and then extend to the inside of the longitudinal movable cavity 22. The longitudinal limiting block 28 at the bottom of the longitudinal movable rod 27 is used to limit the longitudinal movement of the longitudinal movable rod 27.

[0054] In addition, in order to enable the longitudinal movable rod 27 to have a certain buffering function during movement, a first spring 16 is installed on the longitudinal movable rod 27 located between the longitudinal limiting block 28 and the longitudinal through hole 23. The buffering purpose is achieved by compressing or stretching the first spring 16.

[0055] like Figure 10 The clamping block assembly 15 mainly includes a transverse movable rod 29, which can move laterally within the transverse movable cavity 20. A clamping block inclined surface 30 is provided on the right side of the transverse movable rod 29, and a clamping block 31 is provided on the left side of the transverse movable rod 29 after passing through the transverse through hole 21. The clamping block 31 can be installed on the transverse movable rod 29 or integrally formed with the transverse movable rod 29.

[0056] The inclined surface 30 of the clamping block is adapted to the conical block 26. The conical block 26 can squeeze the inclined surface 30 of the clamping block on the right side of the transverse movable rod 29, causing the transverse movable rod 29 to move to the left, thereby driving the clamping block 31 to move to the left.

[0057] A lateral limiting block 32 is also provided on the lateral movable rod 29, which can limit the movement of the lateral movable rod 29 in the lateral direction.

[0058] In addition, in order to enable the transverse movable rod 29 to have a certain buffering function during movement, a second spring 17 is installed on the transverse movable rod 29 located between the transverse limiting block 32 and the transverse through hole 21. The above-mentioned buffering purpose is achieved by compressing or stretching the second spring 17.

[0059] In summary, the working principles of the fixing component 13, driving component 14, and clamping block component 15 of the clamping member 2 in this embodiment are briefly described as follows:

[0060] like Figure 6 In the initial state, the drive component 14 is located at the lowest position, and the clamping block component 15 is located at the leftmost position.

[0061] At this point, the conical block 26 is almost inside the conical groove 19. Then, the conical block 26 moves the transverse movable rod 29 to the left, and the clamping block 31 comes into close contact with the workpiece 3 on the left. At this point, the first spring 16 is in its normal state, and the second spring 17 is in its compressed state.

[0062] like Figure 5 When it is necessary to release the clamping of workpiece 3, the operator pulls handle 25, causing the conical block 26 to move upward within the conical groove 19. At this time, the transverse movable rod 29 will gradually move to the right, causing the clamping block 31 to gradually separate from the workpiece 3 on the left, and then the workpiece 3 can be removed. At this time, the first spring 16 is in a compressed state, and the second spring 17 is in a normal state.

[0063] The second embodiment of this utility model:

[0064] The overall fixing and installation method of tooling base 1:

[0065] like Figure 2 A mounting bracket 4 is provided below the tooling base 1, and a sliding groove 5 is provided in the mounting bracket 4 along the left and right directions. A stop block 6 for limiting the position is provided on the left side of the sliding groove 5, while the right side of the sliding groove 5 is open. When the tooling base 1 is installed on the mounting bracket 4, the tooling base 1 enters from the right side of the sliding groove 5 until it contacts the stop block 6 on the left side of the sliding groove 5, thus completing the initial positioning and installation of the tooling base 1. The guiding effect of the sliding groove 5 ensures good accuracy in the initial positioning and installation of the tooling base 1. After the initial positioning and installation of the tooling base 1 is completed, it is locked together with the mounting bracket 4 below by a spacer block 7.

[0066] like Figure 4 A tooling locking hole 10 is provided on the spacer block 7. Correspondingly, a number of mounting bracket locking holes are evenly provided on the mounting bracket 4 along the left and right directions. After the tooling base 1 is initially positioned and installed, the tooling locking hole 10 is connected to the mounting bracket locking hole directly below by bolts.

[0067] The third embodiment of this utility model:

[0068] Based on the second embodiment described above, a plurality of sliding grooves 5 can be evenly formed along the front-back direction within the mounting frame 4, with the grooves 5 distributed along the left-right direction. This structural design allows multiple tooling bases 1 to be simultaneously positioned and installed on the mounting frame 4, thereby improving its integration performance.
