Description

Technical Field

[0001] The present application relates to the field of chucks, and in particular to an oblique-pull chuck for clamping thin-walled parts. Background Art

[0002] Currently, CNC machine tool chucks are classified as automatic centering chucks. These use an air or oil cylinder mounted at the rear end of the machine tool spindle. A pull rod or tube inserted into the spindle bore pushes and pulls a wedge-shaped sleeve inside the chuck body at the front end of the spindle. The axial movement of the sleeve simultaneously causes radial movement of the jaws, thereby clamping the workpiece. These chucks are structurally complex and, when clamping thin-walled parts, can easily deform the outer surface of the workpiece, potentially damaging it and hindering machining.

[0031] In order to make the purpose, features, and advantages of the invention of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0032] The following is combined with Figure 1-6 This application is described in further detail.

[0033] Example 1:

[0034] The embodiment of the present application discloses a thin-walled component clamping oblique pull chuck, such as Figure 1 As shown, the machine comprises a base 1 and a housing 2. The housing 2 is mounted on the base 1. The base 1 is provided with a first threaded hole 11, and the housing 2 is provided with a second threaded hole 21. Both the first threaded hole 11 and the second threaded hole 21 are provided for screwing bolts. The operator can move the base 1 and the housing 2 to appropriate positions on the machine tool and screw in bolts so that the bolts pass through the second threaded hole 21 and the first threaded hole 11 in sequence, thereby completing the installation of the base 1 and the housing 2.

[0035] like Figure 2 and 3 As shown, a diagonal tie block 4 slides relatively on the base 1. In the embodiment of the present application, there are three diagonal tie blocks 4, which are arranged in a radial ring along the base 1. In this solution, the number of diagonal tie blocks 4 can be set to six, which increases the force points on the workpiece while ensuring stable clamping of the workpiece. The diagonal tie block 4 is arranged at an angle, and the housing 2 is provided with a through hole for the diagonal tie block 4 to pass through. The base 1 is provided with a placement groove 12, and the end of the diagonal tie block 4 closest to the base 1 is located in the placement groove 12. The placement groove 12 can limit the position of the diagonal tie block 4, improving the positioning accuracy of the diagonal tie block 4.

[0036] like Figure 2 and 3 As shown, the base 1 is provided with a control assembly 3 for controlling the sliding movement of the inclined-pull block 4. The control assembly 3 includes a control sleeve 31 and a control disk 32. One end of the control sleeve 31 extends out of the base 1, and the other end is located within the housing 2. The control disk 32 is fixedly mounted on the control sleeve 31 and is located between the base 1 and the housing 2. The inclined-pull block 4 is provided with a control slot 41 for the control disk 32 to be inserted into. When the inclined-pull block 4 needs to be moved, the operator can control the movement of the control sleeve 31. The movement of the control sleeve 31 drives the movement of the control disk 32. When the control disk 32 moves, it abuts against the wall of the control slot 41, thereby achieving movement of the inclined-pull block 4. The through holes provided in the housing 2 can limit the movement of the inclined-pull block 4, facilitating the clamping of the workpiece.

[0037] The implementation principle of the oblique pull chuck for clamping thin-walled parts in the embodiment of the present application is as follows:

[0038] The operator can sequentially pass the bolts through the second threaded hole 21 and the first threaded hole 11 and screw them into the machine tool to install the base 1 and the housing 2. When it is necessary to clamp the workpiece, the operator can apply force to the control sleeve 31. The movement of the control sleeve 31 can drive the movement of the control disk 32. The control disk 32 abuts against the groove wall of the control groove 41, thereby driving the movement of the inclined pull block 4, facilitating the clamping of the workpiece.

[0039] Example 2:

[0040] like Figure 4 As shown, in the embodiment of the present application, based on the first embodiment, a guide rod 13 is fixedly connected to the bottom of the placement groove 12. The guide rod 13 is arranged at an angle, and the length direction of the guide rod 13 is consistent with the sliding direction of the diagonal pull block 4. A guide groove 42 is formed at the end of the diagonal pull block 4 close to the base 1, and the end of the guide rod 13 away from the base 1 is located in the guide groove 42. When the diagonal pull block 4 is located in the placement groove 12, the guide rod 13 is embedded in the guide groove 42. When the diagonal pull block 4 slides, the end of the guide rod 13 away from the base 1 is located in the guide groove 42 and slides. The guide rod 13 can limit the sliding of the diagonal pull block 4, further improving the stability of the diagonal pull block 4 during movement.

[0041] like Figure 4 As shown, a mounting groove 14 is defined at the bottom of the placement groove 12, and a contact sensor 15 is provided on the base 1. The contact sensor 15 is located within the mounting groove 14. When the inclined tie block 4 is located within the placement groove 12, the inclined tie block 4 comes into contact with the contact sensor 15, which then generates a signal, facilitating operator control of the movement of the inclined tie block 4.

[0042] like Figure 5 and 6As shown, a first sliding block 321 is fixedly connected to the lower end surface of the control disk 32, and a first sliding groove 411 is formed on the lower groove wall of the control groove 41. The first sliding block 321 slides in the first sliding groove 411. A second sliding block 412 is fixedly connected to the upper groove wall of the control groove 41. A second sliding groove 322 is formed on the upper end surface of the control disk 32. The second sliding block 412 slides in the second sliding groove 322. When the control disk 32 drives the inclined-bracing block 4 to move, the movement of the control disk 32 can drive the first sliding block 321 to move in the first sliding groove 411, and the first sliding block 321 can limit the movement of the inclined-bracing block 4; the movement of the inclined-bracing block 4 can drive the second sliding block 412 to move in the second sliding groove 322, and the second sliding groove 322 can slide and limit the second sliding block 412, thereby limiting the inclined-bracing block 4 and further improving the stability of the inclined-bracing block 4 during movement.

[0043] The implementation principle of the oblique pull chuck for clamping thin-walled parts in the embodiment of the present application is as follows:

[0044] When the diagonal block 4 is positioned within the placement slot 12, the guide rod 13 engages within the guide slot 42, and the bottom end of the diagonal block 4 contacts the contact sensor 15. The guide rod 13 limits the movement of the diagonal block 4, and the contact sensor 15 generates a signal to facilitate operator control of the movement of the diagonal block 4. When the control panel 32 drives the diagonal block 4 to move, the first sliding block 321 slides within the first sliding slot 411, and the second sliding block 412 slides within the second sliding slot 322, improving the stability of the diagonal block 4 during movement.

[0045] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
