[0001] This utility model belongs to the field of clamping technology, and in particular relates to clamping fingers. Background Technology
[0002] Parallel grippers are commonly used gripping tools in industrial robots or automated equipment, mainly used for grasping, fixing or moving objects. Depending on different application requirements, parallel grippers come in various designs and materials.
[0003] Currently, there are many types of parallel finger clamps, and each type of parallel finger clamp is generally only compatible with one type of drive (such as pneumatic, electric, and hydraulic), resulting in poor adaptability of parallel finger clamps. In addition, the current parallel finger clamps have complex structures and are inconvenient to disassemble. In view of this, we propose a finger clamp. Utility Model Content
[0004] The purpose of this invention is to provide a finger clamp to solve the problems mentioned in the background art.
[0005] In view of this, the present invention provides a finger clamp, including a mounting base, two clamping blocks are provided on the inner side of the mounting base, two connecting shafts are slidably installed between the two clamping blocks, both ends of the two connecting shafts pass through the mounting base, a connecting tube is fixedly installed at the bottom of the mounting base, and a limit block is fixedly installed at the other end of the connecting tube;
[0006] Two sliders are slidably mounted on the middle of the opposite side of two clamping blocks. A movable block is fixedly mounted between the lower ends of the two sliders. The movable block passes through and is slidably connected to the mounting base. A connector is threadedly mounted on the other side of the movable block. A drive rod is fixedly mounted on the other side of the connector. The drive rod passes through the mounting groove, the connecting pipe, and the limiting block.
[0007] A locking assembly is mounted on the connecting shaft and is used to restrict relative movement between the mounting base and the connecting shaft.
[0008] In the above technical solution, the locking component further includes:
[0009] Four retaining rings are respectively sleeved on the outer walls of the two connecting shafts at both ends. All four retaining rings are located inside the mounting base. Annular grooves are provided on the arc-shaped side walls at both ends of the two connecting shafts, and the four retaining rings respectively cooperate with the four annular grooves.
[0010] In the above technical solution, furthermore, springs are fitted on the outer walls of both connecting shafts, and the two ends of the two springs are in contact with the two clamping blocks respectively.
[0011] In the above technical solution, furthermore, the middle part of both clamping blocks is provided with a sloping surface, and the slope of the sloping surface is the same as that of the inclined end of the slider.
[0012] In the above technical solution, the bottom of the movable block is provided with a threaded hole, and the connector is installed in the threaded hole.

[0015] The beneficial effects of this utility model are:
[0016] 1. This clamping finger can be driven by a specified method, such as a pneumatic cylinder, an electric push rod, or a hydraulic cylinder, according to the requirements. The output end of the drive device is then connected to the drive rod via a coupling. By driving the drive rod downward, the movable block and the two sliders move downward along the mounting groove. At the same time, the inclined surfaces on opposite sides of the two sliders move downward along the slope, causing the two clamping blocks to move closer together under the push of the two sliders. It can be adapted to different drive methods.
[0017] 2. When the clamping finger needs to be disassembled, the snap ring on the connecting shaft can be removed, and then the connecting shaft can be pulled out of the clamping block. Then the clamping block, slider and movable block can be taken out from the mounting base, making the structure simple and easy to disassemble. Attached Figure Description

[0034] Example 1:
[0035] Please see Figures 1-9 As shown, this embodiment provides a finger clamp, including a mounting base 1. Two clamping blocks 3 are provided on the inner side of the mounting base 1. Two connecting shafts 2 are slidably installed between the two clamping blocks 3. Both ends of the two connecting shafts 2 pass through the mounting base 1. A connecting pipe 6 is fixedly installed at the bottom of the mounting base 1. A limit block 16 is fixedly installed at the other end of the connecting pipe 6.
[0036] Two sliders 4 are slidably installed in the middle of the opposite side of the two clamping blocks 3. A movable block 5 is fixedly installed between the lower ends of the two sliders 4. The movable block 5 passes through and is slidably connected to the mounting base 1. A connector 11 is threadedly installed on the other side of the movable block 5. A drive rod 7 is fixedly installed on the other side of the connector 11. The drive rod 7 passes through the mounting groove 13, the connecting pipe 6 and the limiting block 16.
[0037] A locking assembly is mounted on the connecting shaft 2 and is used to restrict the relative movement of the mounting base 1 and the connecting shaft 2.
[0038] Among them, a specific drive method can be selected according to the requirements, such as a cylinder, an electric push rod, or a hydraulic cylinder. Then, the output end of the drive device is connected to the drive rod 7 through a coupling, so as to adapt to different drive methods.
[0039] Example 2:
[0040] This embodiment provides a finger clamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the locking component includes:
[0041] Four retaining rings 9 are respectively sleeved on the outer walls of the two connecting shafts 2 at both ends. All four retaining rings 9 are located on the inner side of the mounting base 1. Annular grooves 12 are opened on the arc-shaped side walls at both ends of the two connecting shafts 2. The four retaining rings 9 are respectively engaged with the four annular grooves 12.
[0042] The connecting shaft 2 is held in place by the retaining ring 9, which prevents the connecting shaft 2 from separating from the clamping block 3. When it is necessary to disassemble the clamping finger, the retaining ring 9 on the connecting shaft 2 can be removed, and then the connecting shaft 2 can be pulled out from the clamping block 3. Then the clamping block 3, the slider 4 and the movable block 5 can be taken out from the mounting base 1.
[0043] Example 3:
[0044] This embodiment provides a finger clamp, which, in addition to the technical solution of the above embodiment, also has the following technical features: the outer walls of the two connecting shafts 2 are each fitted with a spring 8, and the two ends of the two springs 8 are respectively in contact with the two clamping blocks 3.
[0045] In this process, the two clamping blocks 3 are gradually separated as the slider 4 rises by the compression of the spring 8.
[0046] Example 4:
[0047] This embodiment provides a finger clamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the middle of both clamping blocks 3 is provided with a ramp surface 10, and the ramp surface 10 has the same slope as the ramp end of the slider 4.
[0048] During the downward movement of the two sliders 4, the inclined surfaces on opposite sides of the two sliders 4 will move downward along the slope surface 10.
[0049] Example 5:
[0050] This embodiment provides a finger clamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the bottom of the movable block 5 is provided with a threaded hole 15, and the connector 11 is installed in the threaded hole 15.
[0051] The threaded connection between the threaded hole 15 and the connector 11 facilitates the connection of the drive rod 7 and the movable block 5, so that pulling the drive rod 7 up or down can move the movable block 5 up or down together.
[0052] Example 6:
[0053] This embodiment provides a finger clamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the mounting base 1 has a mounting groove 13 in the middle, and the movable block 5 is installed in the mounting groove 13.
[0054] Specifically, by pulling down the drive rod 7, the movable block 5 moves downward along the mounting groove 13.
[0055] Example 7:
[0056] This embodiment provides a finger clamp, which, in addition to the technical solutions of the above embodiments, also has the following technical features: two through holes 14 are opened on the side walls of the upper part of the two clamping blocks 3.
[0057] The through hole 14 facilitates the installation of other mechanisms onto the clamping block 3 using bolts.
[0058] Working principle: By pulling down the drive rod 7, and then through the transmission of the connector 11, the movable block 5 moves down along the mounting groove 13. At the same time, the inclined surfaces of the two sliders 4 on opposite sides will move down along the slope surface 10, so that the two clamping blocks 3 will move closer together under the push of the two sliders 4 and compress the spring 8. When the drive rod 7 is pushed up, since the clamping blocks 3 are no longer restrained by the sliders 4, the two clamping blocks 3 will separate to both sides under the pressure of the spring 8. By setting through holes 14, it is convenient to install other mechanisms onto the clamping blocks 3 with bolts.
[0059] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
