Description

Technical Field

[0001] The utility model relates to the technical field of press-fitting, in particular to a clamping press-fitting component. Background Art

[0002] When performing press-fitting and assembling operations on disc and ring parts, it is necessary to first clamp the disc and then place it directly above the ring, and then press the disc into the inner hole of the ring. The common structure in the prior art is to use electric or other clamping power components to achieve the clamping and releasing actions of the clamping jaws. However, for some disc parts with smaller diameters, the clamping power component has high requirements for the clamping jaw driving accuracy, and the equipment cost is high. In addition, when the clamping jaw clamps the disc and places it above the ring, the end of the clamping jaw will be embedded in the bottom of the disc, so it is easy for the disc to be placed at a low position, which affects the press-fitting efficiency and press-fitting quality. Utility Model Content

[0003] The utility model aims to provide a clamping and pressing assembly, which is used to solve the technical problems of high equipment cost, low pressing efficiency and poor pressing quality caused by high clamping precision in the clamping operation of the pressing assembly in the prior art.

[0008] The clamping mechanism includes a plurality of clamping parts for clamping the product. The clamping parts cooperate with the relatively sliding top block and the pressing block to clamp and release the product under the drive of the downward pressing power part, so as to cooperate with the pressing block to press the product.

[0009] Furthermore, the clamping mechanism comprises:

[0010] An upper slider is vertically slidably mounted on the top block and the bottom of the upper slider is in contact with the pressing block;

[0011] The elastic part is located between the upper surface of the upper slider and the downward pressing power part, and has a tendency to make the upper slider move vertically downward.

[0012] The lower slider is installed below the upper slider and is slidably installed with the pressure block in the vertical direction. The outer circumference of the lower slider is provided with a number of longitudinal slide grooves corresponding to the clamping part in the vertical direction. The longitudinal slide groove is used for the clamping part to be embedded. The outer circumference of the lower slider is provided with an annular limit groove in the circumferential direction. An elastic limit part is installed in the annular limit groove. The elastic limit part is used to limit the clamping part to be installed in the longitudinal slide groove and has a tendency to move the clamping part toward the lower slider. When the bottom of the clamping part is subjected to external force, it moves away from the lower slider under the joint action of the elastic limit part.

[0013] Furthermore, a lower convex portion is provided at the bottom of the clamping portion, which is inclined toward the side close to the pressing block, and includes an upper inclined surface, a vertical surface and a lower inclined surface. The upper inclined surface and the lower inclined surface are respectively located on the upper side and the lower side of the vertical surface.

[0014] Furthermore, an upper convex portion inclined toward a side close to the pressing block is provided on the top of the clamping portion, and a groove is provided on the outer side of the middle portion connecting the upper convex portion and the lower convex portion, and the groove is used for the elastic limiting portion to be embedded.

[0015] Furthermore, a transverse avoidance groove is provided at the bottom of the upper sliding block in a radial direction, and the transverse avoidance groove is used for the upper protrusion of the clamping part to be embedded.

[0016] Furthermore, a sliding hole is axially arranged in the upper sliding block, and the sliding hole is slidably matched with the outer peripheral surface of the top block.

[0017] Furthermore, the outer circumferential shape of the top block includes two arc surfaces and two planes, the arc surfaces and the planes are arranged in pairs, the shape of the sliding hole of the upper slider matches the top block, and a circular hole avoidance groove is provided at the junction of the arc surface and the plane of the sliding hole to avoid the corner of the junction of the arc surface and the plane of the top block.

[0018] Furthermore, the top block and the pressing block are connected by a connecting block, and the pressing block and the connecting block are relatively fixedly installed. The connecting block is configured as a T-shaped block, the large end of the connecting block is located in the inner hole of the top block, the small end of the connecting block is installed in contact with the pressing block, and a pressure plate is installed at the bottom of the top block to limit the downward movement of the large end of the connecting block.

[0019] Furthermore, the angles between the upper inclined surface and the lower inclined surface and the vertical surface are both obtuse angles.

[0020] Furthermore, a concave stop is provided at the bottom of the upper sliding block, and the concave stop is installed in contact with the top of the pressing block.

[0021] Compared with the prior art, the technical solution of the utility model has the following beneficial effects:

[0022] (1) The utility model provides a top block, a pressure block and a clamping mechanism, as well as a specific structure of the clamping mechanism, so that during the pressing process driven by the pressing power unit, after the pressure block contacts the product and the clamping part contacts the product, the lower end of the clamping part moves in a direction away from the lower slider under the joint action of the product pressure and the elastic limiting part, so that the product to be clamped slides in sequence along the lower inclined surface, vertical surface and upper inclined surface of the clamping part, thereby achieving the clamping of the product by the clamping part. When press-fitting is required, the clamping part places the product just above the pressed product under the drive of the pressing power unit. During the pressing process, the lower end of the clamping part transmits the force to the elastic limiting part and the elastic part, and the lower end of the clamping part moves in a direction away from the lower slider, so that the clamped product is separated from the clamping part and fully contacts the product to be pressed for press-fitting. No additional power is required for the clamping and releasing actions during the entire process, which saves equipment costs and improves press-fitting efficiency and quality.

[0023] (2) The utility model provides an elastic limiting portion, which can not only limit the clamping portion but also allow the clamping portion to reciprocate in a certain range along the radial direction, and the structural design is ingenious. BRIEF DESCRIPTION OF THE DRAWINGS
