Specifically, the connecting member 100 is an elastic connecting member, and during the clamping process of the clamping assembly 200, the connecting member 100 is elastically connected to the clamping assembly 200 to ensure that the workpiece is in elastic contact when in contact with the workpiece, so as to avoid the workpiece from being scratched by hard contact.

The at least one clamping assembly 200 comprises two clamping assemblies 200 arranged in mirror symmetry. The two clamping assemblies 200 are fixedly connected to the connector 100, and the structures and functions of the two clamping assemblies 200 are identical, and only the specific structure and function of one clamping assembly 200 will be described in detail hereinafter.

The press-in component 400 is fixedly connected with the connecting piece 100, and after the clamping component 200 clamps the workpiece for installation, the press-in component 400 is assisted to press the workpiece into a proper position. The specific structure and function of the press-in assembly 400 will be described in detail later.

Referring to fig. 1, 2 and 3, each clamping assembly 200 includes a fixing plate 210, a clamping member 220 and a clamping driving member 230. The fixing plate 210 is fixedly connected to the connecting member 100, the clamping member 220 is fixed on the fixing plate 210, and the clamping driving member 230 is fixed on the fixing plate 210 by a fixing member (not shown), which may be a screw or other fixing member. The clamping driving member 230 is connected with the clamping member 220 in a driving manner, and the clamping driving member 230 drives the clamping member 220 to clamp the workpiece. Specifically, the clamping member 220 includes a fixed end 221, a moving end 222, a slider 223, and a stopper 224. The fixed end 221 is fixed to the fixing plate 210. The limiting block 224 has a receiving cavity 2241, and the movable end 222 is at least partially received in the receiving cavity 2241. The sliding block 223 is fixedly connected with the power output end of the clamping driving member 230, and the sliding block 223 penetrates through the accommodating cavity 2241 and abuts against the moving end 222. The stopper 224 limits the slider 223 from moving in a first direction (i.e., the Y-axis direction in the figure), while the stopper 224 limits the moving end 222 from moving in a second direction (i.e., the X-axis direction in the figure), the first direction being perpendicular to the second direction. It can be understood that the clamping driving member 230 drives the sliding block 223 to move along the first direction to hold the moving end 222 to move towards the fixed end 221 along the second direction, and the moving end 222 and the fixed end 221 are close to each other to complete clamping of the workpiece.

In some other embodiments, the position of the slider 223 and the movable end 222 can be adjusted to enable the first direction and the second direction to be obliquely arranged, that is, the first direction and the second direction control the clamping member 220 to clamp the workpiece if the first direction and the second direction are not perpendicular.

In an embodiment, referring to fig. 3 and fig. 4, a protrusion 2221 protrudes from a contact surface of the moving end 222 and the sliding block 223, the sliding block 223 is provided with a groove 2231, and the sliding slot 311 is in abutting fit connection with the protrusion 2221.

When the clamping member 220 needs to clamp a workpiece, the clamping driving member 230 drives the sliding block 223 to move along a first direction, during the movement of the sliding block 223, the trapezoidal inclined surface of the projection 2221 gradually moves along the inclined surface of the groove 2231 until the projection 2221 completely moves out of the trapezoidal groove 2231, and during the movement of the sliding block 223 along the first direction, the sliding block 223 abuts against the sliding block 223 to move along a second direction.

In some preferred embodiments, in order to precisely clamp a small workpiece, the movable end 222 is embedded with a first clamping end 2222, the fixed end 221 is embedded with a second clamping end 2211, the first clamping end 2222 and the second clamping end 2211 are oppositely arranged to clamp the workpiece, and the clamping ends of the first clamping end 2222 and the second clamping end 2211 are vertically arranged away from the fixed plate 210. The needle 201 is detachably mounted on the end portions of the first holding end 2222 and the second holding end 2211, when the first holding end 2222 and the second holding end 2211 move to clamp a workpiece, the first holding end 2222 approaches the workpiece along the Z-axis direction, and the first holding end 2222 approaches the second holding end 2211 along the X-axis direction to clamp the workpiece.

Referring to fig. 4 again, in order to ensure that the workpiece clamped by the clamping member 220 is removed, the movable end 222 and the fixed end 221 of the clamping member 220 are restored to the original positions for the next clamping operation. An elastic member 225 is disposed between the movable end 222 and the fixed end 221, one end of the elastic member 225 is fixedly connected to the fixed end 221, and the other end abuts against the movable end 222. When the workpiece clamped by the clamping member 220 is removed, the clamping driving member 230 drives the sliding block 223 to move away from the first direction, the groove 2231 of the sliding block 223 gradually approaches the projection 2221 to leave a matching space for the projection 2221 of the moving end 222, and at this time, the moving end 222 drives the projection 2221 of the moving end 222 to move towards the groove 2231 under the elastic force of the elastic member 225, so as to open the moving end 222 and the fixed end 221.

Referring to fig. 2 and 3, in other preferred embodiments, the clamping and positioning device 10 further includes a positioning member 300 for adjusting the position of the movable end 222.

Each press-in rod 430 independently presses against a workpiece, and the press-in rods 430 elastically and adaptively press the workpieces to different positions according to different workpieces.

Further, referring to fig. 1 and 2 again, the press-in rod 430 is axially parallel to the first clamping end 2222 and the second clamping end 2211, so that the press-in direction of the press-in rod 430 and the clamping member 220 is the same as the clamping process moving direction, i.e. both move in the Z direction.
