Abstract
Description
Technical Field
[0001] This utility model relates to the field of clamping equipment technology, specifically a miniature clamping fixture. Background Technology
[0002] In the field of micro-part machining and assembly, traditional clamping fixtures often fall short of the requirements due to the small size and high precision of the parts. Therefore, micro-clamping fixtures have emerged to meet the positioning and clamping requirements in the machining and assembly of micro-parts. With the continuous development of micro-nano manufacturing technology, micro-clamping fixtures will evolve towards higher precision, smaller size, and stronger functionality. Simultaneously, to meet the needs of different fields, micro-clamping fixtures will continue to be innovated and improved.
[0003] The existing technology still has the following drawbacks in its use:
[0004] Existing clamping fixtures typically have poor precision when clamping, perform only a single clamping action, occupy a relatively large space, and have a slow operating speed, making it impossible to achieve higher production capacity.
[0005] In view of this, we propose a miniature clamping fixture to solve the existing problems. Utility Model Content
[0006] The purpose of this invention is to provide a miniature clamping fixture to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a miniature clamping fixture, comprising a clamping cylinder, one end of which is connected to an mounting block, a connecting block, and a telescopic rod passing through the mounting block. A cylinder sliding connecting rod is connected to the front end of the telescopic rod. A protective pressure plate is mounted on one side of the cylinder sliding connecting rod, and a sliding support is mounted on the side of the cylinder sliding connecting rod away from the protective pressure plate. A clamping support is provided at the lower end of the cylinder sliding connecting rod, and two sets of gripper heads are provided at the lower end of the clamping support. A second sliding groove is provided at the upper end of the sliding support, and a first sliding groove is provided at the lower end of the sliding support. A second sliding element is provided on the cylinder sliding connecting rod, and the cylinder sliding connecting rod and the sliding support are connected through the second sliding groove. A first sliding element is provided at the upper end of the gripper head, and the gripper head and the sliding support are connected through the first sliding groove.
[0008] Preferably, the first sliding groove is symmetrically arranged based on the sliding support, and the first sliding member at the upper end of each set of gripper heads is symmetrically arranged based on the gripper heads.
[0009] Preferably, a positioning pin is provided at the lower end of the connecting block.
[0010] Preferably, the lower end of the cylinder sliding connecting rod is provided with multiple sets of one-to-one corresponding clamping supports and sliding supports at equal intervals.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] This invention uses a set of connecting rods to push the gripper to slide in the inclined groove, which can effectively control the clamping and releasing actions of the gripper. Multiple sets can clamp simultaneously, improving clamping efficiency. The overall structure has advantages such as high precision, small space occupation, fast operation speed, and high production capacity. Attached Figure Description

[0017] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0018] Example 1
[0019] like Figure 1 , Figure 2 and Figure 3As shown, this utility model proposes a miniature clamping fixture, including a clamping cylinder 1. One end of the clamping cylinder 1 is connected to a mounting block 3, and a connecting block 4 is also connected to the clamping cylinder 1. The mounting block 3 and the connecting block 4 form an integral mounting frame. A telescopic rod 2 is connected to the clamping cylinder 1 through the mounting block 3. The telescopic rod 2 moves under the drive of the clamping cylinder 1. A cylinder sliding connecting rod 6 is connected to the front end of the telescopic rod 2, and the cylinder sliding connecting rod 6 moves along with the telescopic rod 2. A protective pressure plate 5 is installed on one side of the cylinder sliding connecting rod 6 to protect and fix the position of the clamping support 7. A sliding support 9 is installed on the side of the cylinder sliding connecting rod 6 away from the protective pressure plate 5 to control the movement of the gripper head 8. The clamping support 7 is provided at the lower end of the cylinder sliding connecting rod 6 to mount and support the gripper head 8. The 8-axis moves, and the lower end of the clamping support 7 is provided with two sets of gripper heads 8. The gripper heads 8 can clamp and release by moving in the inclined groove. The upper end of the sliding support 9 is provided with a second sliding groove 12, and the lower end of the sliding support 9 is provided with a first sliding groove 11. The cylinder sliding connecting rod 6 is provided with a second sliding member 13. The cylinder sliding connecting rod 6 and the sliding support 9 are connected through the second sliding groove 12. The upper end of the gripper head 8 is provided with a first sliding member 10. The gripper head 8 and the sliding support 9 are connected through the first sliding groove 11. When the cylinder sliding connecting rod 6 moves, the second sliding member 13 moves in the second sliding groove 12 to control the up and down movement of the sliding support 9. During the up and down movement of the sliding support 9, the first sliding member 10 moves in the first sliding groove 11 to drive the clamping and releasing action of the gripper head 8.
[0020] Furthermore, the first sliding groove 11 is symmetrically arranged based on the sliding support member 9, and the first sliding member 10 at the upper end of the single set of gripper heads 8 is symmetrically arranged based on the gripper heads 8, so that the two sets of gripper heads 8 can effectively perform symmetrical clamping.
[0021] Furthermore, a positioning pin 14 is provided at the lower end of the connecting block 4. The positioning pin 14 is used to assist in the installation of the connecting block 4 and the protective pressure plate 5.
[0022] Furthermore, multiple sets of one-to-one corresponding clamping supports 7 and sliding supports 9 are equidistantly arranged at the lower end of the cylinder sliding connecting rod 6, and the clamping supports 7 and sliding supports 9 of each set cooperate with each other.
[0023] The above specific embodiments are merely several preferred embodiments of this utility model.
