Description

Technical Field

[0001] The invention relates to the technical field of slide feeding, and in particular to a small slide feeding clamping device. Background Art

[0002] A small slide is a compact linear motion device, usually composed of a guide rail, a slider and a drive system. It is designed to save space and is suitable for precision operations and material handling or positioning in a small environment. The small slide can provide smooth linear motion and is widely used in automation equipment, mechanical processing, laboratory instruments and other fields. Due to its small size and high precision, the small slide is particularly suitable for work scenarios that require high efficiency and high accuracy, such as electronic component assembly and micro-machining. The small slide feeding and clamping device is an automation device that combines the functions of a small slide, and is mainly used for the transportation and clamping of materials. The device uses the linear motion of the small slide to accurately deliver the workpiece to the specified position, and uses the clamping mechanism to firmly grasp the workpiece, and then transports the workpiece to the specified position for processing or packaging, etc.

[0003] When a small slide is used to transport workpieces, when multiple workpieces are transported at the same time, its clamping device may need to clamp multiple workpieces synchronously at the same time and then move them to the specified position. However, the existing clamping device and each group of clamping parts may have a fixed structure. Therefore, after the material on the slide is clamped and sent to the specified position, it may be necessary to rearrange the spacing between the multiple workpieces according to different processing and packaging requirements. The operation is relatively cumbersome, which affects its actual work efficiency. At the same time, in the process of transferring materials, in order to avoid collisions between the workpieces during movement, not only an axial reciprocating movement mechanism is required, but also a repeated lifting mechanism is required to avoid direct translation of the workpieces, causing collisions, etc. Its structural components are relatively complex, and the subsequent use and maintenance costs will also be relatively high.

[0004] In view of this, a small slide feeding clamping device is provided. Summary of the invention

[0005] In view of the above-mentioned shortcomings of the prior art, the present invention provides a small slide feeding and clamping device, which can effectively solve the problem of simultaneous clamping of multiple workpieces in the prior art, wherein the multiple clamping parts have a fixed structure, and after the workpieces are clamped and moved, they need to be rearranged and moved, which is inconvenient to operate and affects work efficiency, and the structure is complex and the cost of later use and maintenance is high.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solutions:

[0008] A fixing frame is also fixedly installed on one side of the push-pull rod, and two sets of slide grooves are opened on the inner cavity side wall of the fixing frame. Guide plates are slidably installed on the inner cavity side walls of the two sets of slide grooves, and multiple sets of radial guide grooves are opened on the surface of the guide plate.

[0009] Among them, a driving mechanism is provided at the end of the connecting rod away from the connecting rod, and the connecting rod can be driven by the driving mechanism to rotate forward and reverse, and one side of the multiple groups of guide rods is provided with a clamping piece. By raising and lowering the guide plate in the slide groove, the distance between the clamping pieces on one side of the multiple groups of guide rods can be adjusted.

[0010] Furthermore, the driving mechanism includes a gear fixedly mounted on an end of the connecting rod away from the connecting rod, a rack is meshedly connected below the gear, and a sliding frame is fixedly mounted on the bottom of the rack.

The driving mechanism includes a gear 15 fixedly installed on the end of the connecting rod 21 away from the connecting rod 5. The gear 15 is meshed with a rack 14 below. A sliding frame 13 is fixedly installed on the bottom of the rack 14. A second slide rail 12 is slidably installed on the bottom of the sliding frame 13.
