Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.

[0023] like Figures 1 to 6 As shown, the linkage support device of the auxiliary support is provided on the auxiliary support body 1. It can be respectively set at both ends of the workpiece to support the bottom of both ends of the workpiece. It works in conjunction with the workpiece top support mechanism and the workpiece side bottom support device provided on the auxiliary support body 1 to fix the entire workpiece, so as to facilitate workpiece processing. The workpiece top support mechanism includes a pressure claw 2, a pressure claw push rod 3, a push rod return spring 4, an upper push drive rod 5 that is rotatably installed and hinged to the pressure claw push rod 3, and a control screw 6 that cooperates with the upper push drive rod 5. The workpiece side bottom support device includes an adjustable support 7, an adjusting handwheel 8, etc. These are all well known to those skilled in the art and will not be described in detail here.

[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the linkage support device of the auxiliary support includes at least two linearly arranged and vertically installed workpiece support columns 9. These workpiece support columns 9 provide multi-point support for the workpiece, improving its stability and enabling it to withstand the impact forces generated during machining operations, thus facilitating successful machining. Each workpiece support column 9 has a cylindrical support column guide sleeve 10 with open ends movably fitted around its outer periphery. The support column guide sleeve 10 is vertically mounted on the auxiliary support body 1. A support column return spring 11 is fitted at the upper limit of each workpiece support column 9 located within the support column guide sleeve 10. The workpiece support column 9 can move up and down along the support column guide sleeve 10 and automatically return to its original position under the action of the support column return spring 11. When the workpiece support column 9 moves upward, it tightens the workpiece to facilitate machining; after machining is completed, the workpiece support column 9 moves downward to release the workpiece.

[0025] In this embodiment, a dust cover 12 is fixedly installed on the top of the workpiece support column 9, and the dust cover 12 is movably fastened to the outer periphery of the support column guide sleeve 10. A workpiece support nail 13 is installed on the dust cover 12. The dust cover 12 encloses the port of the support column guide sleeve 10 to prevent foreign objects from falling into the support column guide sleeve 10. After the workpiece support column 9 moves upward, the workpiece support nail 13 contacts the bottom of the workpiece to support its processing, while simultaneously fixing the dust cover 12. A support column limiting port 14 is provided on the side wall of the workpiece support column 9, and a limiting pin 15 is provided on the support column guide sleeve 10, which penetrates the support column limiting port 14. Through the cooperation of the limiting pin 15 and the support column limiting port 14, the workpiece support column 9 is blocked from rotating, allowing it to only move linearly up and down. In this embodiment, the support column limiting port 14 is arranged opposite to each other on both sides of the workpiece support column 9, and correspondingly two limiting pins 15 are provided, that is, the two limiting pins 15 clamp the workpiece support column 9.

[0026] The auxiliary support body 1 is connected to a horizontally arranged linkage control channel 16 located directly below each of the support column guide sleeves 10. The linkage control channel 16 is equipped with a manual linkage control device for controlling the vertical displacement of each of the workpiece support columns 9. By operating the manual linkage control device, the vertical displacement control of each of the workpiece support columns 9 can be realized, that is, the linkage control of each of the workpiece support columns 9 can be realized.

[0027] Specifically, the manual linkage control device includes a support column displacement driving block 17 fitted inside the linkage control channel 16 and correspondingly located directly below each support column guide sleeve 10. Each support column displacement driving block 17 has a driving block wedge surface 18 at its top end. The bottom end of the workpiece support column 9 has a support column wedge surface 19 that cooperates with the driving block wedge surface 18. The support column wedge surface 19 cooperates with the driving block wedge surface 18. The workpiece support column 9 is driven to move upward by the translation of the support column displacement driving block 17, and the workpiece support column 9 is driven to move downward and return to its original position by the action of the support column return spring 11. A manual control device is abutted against the support column displacement drive block 17 located at one end of the linkage control channel 16, and the manual control device extends to the outside of the linkage control channel 16. A drive block return device is installed on the support column displacement drive block 17 located at the other end of the linkage control channel 16. A drive block linkage device is provided between two adjacent support column displacement drive blocks 17 located within the linkage control channel 16. By rotating the manual control device, each support column displacement drive block 17 can be moved to the left, so that the bottom end of the drive block wedge surface 18 contacts the support column wedge surface 19, causing the workpiece support column 9 to move down to release the workpiece. When the manual control device is rotated in the opposite direction, the manual control device moves to the right. With the cooperation of the drive block return device and the drive block linkage device, each support column displacement drive block 17 moves to the right, so that the high end of the drive block wedge surface 18 contacts the support column wedge surface 19, causing the workpiece support column 9 to move up to tighten the workpiece.

[0028] The manual control device includes a channel end cap 20 that seals the port of the linkage control channel 16. A drive screw 21 is threaded through the channel end cap 20. The contact surface between the channel end cap 20 and the drive screw 21 is provided with an internal thread. The inner end of the drive screw 21 abuts against the support column displacement drive block 17 located at the end of the linkage control channel 16. A control handwheel 22 is fixedly installed on the outer end of the drive screw 21. By rotating the control handwheel 22 in different directions, the drive screw 21 can be rotated inward or outward, thereby driving the support column displacement drive block 17 to translate to the left or right.

[0029] The drive block return device includes a sealing end cap 23 that seals the port of the linkage control channel 16. A drive block return spring 24 is installed between the sealing end cap 23 and the support column displacement drive block 17 at the other end of the linkage control channel 16, providing a limiting position. The drive block linkage device includes a linkage drive column 25 fixedly connected to one of the support column displacement drive blocks 17. A drive column return spring 26 is fitted on the linkage drive column 25. When the drive screw 21 is externally rotated, the elastic force of the drive block return spring 24 is released, pushing the adjacent support column displacement drive block 17 back, so that the bottom end of the drive block wedge surface 18 contacts the support column wedge surface 19, thereby realizing the upward drive of the workpiece support column 9 and completing the workpiece clamping. At the same time, the elastic force of the drive column return spring 26 is also released, pushing the adjacent support column displacement drive block 17 back, realizing the linkage control of each workpiece support column 9.

[0030] In this embodiment, two mounting recesses 27 are provided on the auxiliary support body 1 corresponding to the linkage drive column 25, and the two mounting recesses 27 are connected through the linkage control channel 16. A column sleeve is fitted on the linkage drive column 25 between the two mounting recesses 27 to limit the return spring 26 of the drive column, and at the same time, the configuration length of the return spring 26 of the drive column can be reduced. The surface of each support column displacement drive block 17 is provided with a drive limiting port 28. A drive limiting bolt 29 extending into the drive limiting port 28 is installed through the auxiliary support body 1. The translation stroke of the support column displacement drive block 17 is controlled by the cooperation between the drive limiting port 28 and the drive limiting bolt 29, and it also acts as a stall to ensure the accurate cooperation between the wedge surface 18 of the drive block and the wedge surface 19 of the support column.

[0031] The working process of this embodiment is as follows:

[0032] Before placing the workpiece: the control handwheel 22 drives the drive screw 21 to rotate, causing the drive screw 21 to move inward. Under the action of the linkage drive column 25, each of the support column displacement drive blocks 17 is pushed to the left. Under the action of the support column return spring 11, the workpiece support column 9 moves down and is in a suspended state.

[0033] After the workpiece is placed, the control handwheel 22 drives the drive screw 21 to rotate, causing the drive screw 21 to move outward. Under the action of the drive block return spring 24, the drive column return spring 26, and the linkage drive column 25, each of the support column displacement drive blocks 17 moves to the right, the support column return spring 11 is compressed, and the workpiece support column 9 moves upward to press against the workpiece.

[0034] Therefore, this embodiment can control the up and down movement of at least two workpiece support columns 9 at one time by using one control handwheel 22, which simplifies the external structure of the auxiliary support body 1 and reduces the installation arrangement of the control handwheel 22.

[0035] The description of this utility model is given for illustrative and descriptive purposes only, and is not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical application of the utility model, and to enable those skilled in the art to understand the utility model and design various embodiments with various modifications suitable for a particular purpose.
