Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mechanical processing devices, in particular to a horizontal plane regulating device used for a chuck. Background Art
[0002] A chuck is a mechanical device used on machine tools to clamp workpieces. It is a machine tool accessory that clamps and positions the workpiece by radial movement of movable jaws evenly distributed on the chuck body.
[0003] When a workpiece needs to be processed horizontally, the bottom surface of the workpiece needs to be placed on the movable jaws first, and then the movable jaws are driven to move radially along the chuck body to approach and clamp the workpiece, and finally the workpiece is processed.
[0004] However, in the existing clamping work, only the fixed plane of the movable clamping jaws contacts the bottom surface of the workpiece. When the bottom surface of the workpiece is uneven, it is necessary to readjust the levelness of the entire chuck; or the workpiece needs to be reprocessed to remove more machining allowances to adjust the flatness of the bottom surface of the workpiece, making the entire clamping work time-consuming and labor-intensive, and reducing the efficiency of the chuck in horizontally clamping the workpiece. Utility Model Content
[0005] In view of the above problems, the utility model provides a horizontal plane adjustment device for a chuck, the purpose of which is to improve the efficiency of horizontally clamping a workpiece.
[0006] In order to achieve the above-mentioned invention object, the technical solution adopted by the utility model is as follows:
[0007] Provided is a horizontal plane adjustment device for a chuck, comprising: a chuck and a movable jaw, wherein a plurality of movable jaws are movably arranged on the chuck, a supporting component is slidably installed on the movable jaw, one end of which is used to abut a workpiece, and the other end extends toward the inside of the movable jaw; an adjusting component is arranged in the movable jaw and can slide along a fixed path; a resistance surface is arranged on the adjusting component and is used to carry the supporting component; wherein the adjusting component slides along the fixed path and can drive the resistance surface to push the supporting component, thereby changing the height of the protruding movable jaw.
[0008] Furthermore, the adjusting component and the movable claw are connected via threads.
[0009] Furthermore, the abutment surface is a conical surface.
[0010] Furthermore, the angle α between the abutment surface and the central axis of the adjustment component is 22.5°.
[0011] Furthermore, the adjusting device also includes a conducting component rotatably disposed on the supporting component for contacting the abutting surface.
[0012] Furthermore, the conductive component is cylindrical.
[0013] The beneficial effects of the utility model are as follows: by using the utility model, the workpiece to be processed can be adjusted horizontally on the movable clamping jaw, which can meet the clamping needs of workpieces with irregular bottom surfaces. During the clamping process, there is no need to horizontally adjust the entire chuck or reprocess the bottom surface of the workpiece, which can effectively improve the clamping efficiency of irregular workpieces.

[0015] Among them, 1. movable claw; 2. supporting component; 3. adjusting component; 4. resistance surface; 5. conducting component. DETAILED DESCRIPTION
[0016] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.
[0017] Reference Figure 1 As shown, an embodiment of the present application discloses a horizontal plane adjustment device used for a chuck, comprising: a chuck and a movable jaw 1, a plurality of movable jaws 1 are movably arranged on the chuck, a supporting component 2 is slidably installed on the movable jaw 1, one end of which is used to abut a workpiece, and the other end extends toward the movable jaw 1; an adjusting component 3 is arranged in the movable jaw 1 and can slide along a fixed path; a contact surface 4 is arranged on the adjusting component 3 and is used to carry the supporting component 2; wherein, the adjusting component 3 slides along the fixed path, which can drive the contact surface 4 to push the supporting component 2, thereby changing the height of the protruding movable jaw 1.
[0018] During specific use, the chuck and the movable jaw 1 are both installed horizontally, and the workpiece to be processed is first placed on the movable jaw 1, and the movable jaw 1 is driven close to the workpiece, with a gap of 0-1mm, and then the spirit level is placed on the surface to be processed of the workpiece; then, the staff drives the adjusting component 3 to slide along a fixed path to adjust the height of the adjusting components 3 on several movable jaws 1 protruding from the movable jaws 1, until the spirit level reaches a horizontal state, and finally drives the movable jaw 1 to move until the workpiece is clamped.
[0019] By using the utility model, the workpiece to be processed can be adjusted horizontally on the movable clamping jaw 1, which can meet the clamping needs of workpieces with irregular bottom surfaces. During the clamping process, there is no need to adjust the entire chuck horizontally or reprocess the bottom surface of the workpiece, which can effectively improve the clamping efficiency of irregular workpieces.
[0020] Specifically, the adjusting component 3 and the movable claw 1 are connected by threads, and the staff can drive the adjusting component 3 to slide by turning the adjusting component 3; through the threaded connection, when the staff does not turn the adjusting component 3, the adjusting component 3 can also be locked to prevent the adjusting component 3 from sliding.
[0021] Specifically, the abutment surface 4 is a conical surface. When the adjusting component 3 slides, the abutment surface 4 can be driven to press the supporting component 2 , thereby pushing the adjusting component 3 to protrude the movable claw 1 .
[0022] Specifically, the angle α between the abutment surface 4 and the central axis of the adjustment component 3 is 22.5°.
[0023] Among them, the adjusting device also includes a conducting component 5, which is rotatably arranged on the supporting component 2 and is used to contact the resistance surface 4; by setting the conducting component 5, the supporting component 2 and the adjusting component 3 are brought into rolling contact, which can effectively reduce the friction generated by the adjusting component 3 pushing the supporting component 2 and extend the service life.
[0024] Specifically, the conductive component 5 is cylindrical, and there is point-to-point contact between the conductive component 5 and the abutment surface 4, which can reduce the contact area between the conductive component 5 and the adjustment component 3 and further reduce friction.
[0025] It is worth mentioning that the conducting component 5 can be rotatably mounted on the supporting component 2 via a rotating shaft, or can be embedded and mounted on the supporting component 2 in a rolling manner.
[0026] It should be understood by those skilled in the art that, although preferred embodiments of the present invention have been described, those skilled in the art may make additional changes and modifications to these embodiments once they are aware of the basic creative concepts. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present invention. Obviously, those skilled in the art may make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the equivalent technology of the claims of the present invention, the present invention is also intended to include these modifications and variations.
