The application relates to the technical field of positioning and clamping devices, in particular to a device for positioning and clamping an inner hole product.

Background

When the products are required to be processed or assembled, the clamping device is generally used for clamping and fixing two sides of the outside of the products, and then the products are processed and assembled. Although this allows the product to be secured, there are a number of inconveniences, such as: when the outer wall of the product needs to be processed, the clamping device can shield the part of the outer wall of the product, so that the whole outer wall of the product cannot be processed; when the product is required to be assembled with the adaptive hole site, the clamping device clamps the product, then the product is placed in the hole site, and because the clamping device can be blocked outside the hole site, only a part of the product can be placed in the hole site, then the product is loosened to enable the product to fall into the hole site completely, when a gap exists between the inner wall of the hole site and the outer wall of the product, the position of the product falling into the hole site is easy to change, accurate positioning assembly cannot be realized, and the assembly precision is reduced.

Disclosure of utility model

The application aims to solve the following problems: when the existing clamping device clamps the inner hole product, the processing quality and the assembly precision of the inner hole product can be affected. Thereby providing a means for locating and clamping the bore product.

In order to solve the technical problems, the technical scheme of the application is as follows: an apparatus for locating and clamping an interior bore product, comprising:

the positioning column is vertically arranged, and the diameter of the lower port is gradually reduced;

the elastic pieces are vertically arranged at positions, close to the lower ends, of the positioning columns, the lower ends are used as fixed ends to be connected with the positioning columns, the upper ends are movable ends, gaps are reserved between the elastic pieces and the positioning columns, and the gaps gradually extend from bottom to top;

The push plate is horizontally sleeved on the positioning column and can move up and down;

and the power mechanism is used for pushing the push plate to move up and down.

Preferably, the plurality of elastic sheets are sequentially arranged along the circumferential direction of the positioning column.

Preferably, the width of the elastic sheet is gradually reduced from bottom to top.

Preferably, the device further comprises a positioning seat;

The positioning column is detachably arranged below the positioning seat.

Preferably, the lower extreme of positioning seat is equipped with vertical mounting groove, the lateral wall level of positioning seat wear to be equipped with the first through-hole of mounting groove intercommunication, the second through-hole is worn to be equipped with to the level on the reference column, be equipped with on the positioning seat and pass in proper order the second through-hole with the fastener of first through-hole.

Preferably, the first through hole and the second through hole Kong Juti are threaded holes, and the fastener is specifically a bolt.

Preferably, the power mechanism is specifically a sliding table cylinder.

Preferably, the sliding table cylinder comprises a fixed part and a movable part, wherein the fixed part is attached to the outer side wall of the positioning seat, and the lower end of the movable part is connected with the push plate.

Preferably, the fixing part is detachably connected with the positioning seat.

Preferably, the main body of the positioning column is cylindrical.

The technical scheme of the application has the following advantages:

1. When the product body with the inner hole needs to be fixed, the product body is sleeved upwards along the lower end of the positioning column, the inner side wall of the inner hole extrudes the elastic sheet, the elastic sheet gives an outward acting force to the inner side wall of the inner hole and generates relative friction force, the product body is prevented from falling downwards, and the product body can be fixed on the positioning column. When the product body needs to be taken away, the power mechanism is started to work, the push plate is pushed downwards by the power mechanism, the product body is pushed downwards by the push plate, the push plate gives the thrust force of the product body to overcome the relative friction force between the product body and the elastic sheet, so that the product body moves downwards until the product body is completely separated from the positioning column. It is to be noted that, when fixing the hole of product body through reference column and shell fragment, can not contact the outer wall of product body to can not lead to the fact the hindrance to the processing of product body outer wall, help improving processingquality, also can not leave the mar at the outer wall of product body. When the product body is required to be transferred to a corresponding hole site for assembly, the product body is conveyed to the position right above the hole site through the positioning column, the lower end of the product body is close to an opening of the hole site, then the power mechanism is started to work, the push plate is pushed downwards by the power mechanism, the product body is pushed downwards by the push plate, the product body gradually falls into the hole site, the positioning column enables the product body to have a limiting effect in the process that the product body falls into the hole site, the product body is enabled to move along the axial direction of the positioning column, the product body is not offset, the assembly precision of the product body and the hole site is improved, and the quality of a final finished product is improved.

2. The shell fragment is arranged in proper order along the circumference of reference column and is set up, can strengthen the fixed centre gripping effect to the product body, also prevents to lead to the product body to take place the skew when the equipment because shell fragment distributes unevenly. The width of shell fragment from bottom to top convergent setting for the lower extreme and the reference column of shell fragment are connected more stably, prevent that the connection between shell fragment lower extreme and the reference column from taking place not hard up, rupture scheduling problem.

3. When the positioning column is installed, the positioning column is inserted into the installation groove, and then the bolts sequentially penetrate through the first through hole and the second through hole, so that the positioning column is installed. When the positioning column needs to be replaced, the bolt is taken out, the positioning column is pulled out from the mounting groove, and a new positioning column is put in again. The positioning column is installed and disassembled by the method, so that the positioning column is very simple and convenient, stable in connection and high in practicability. The purpose of setting the power mechanism as the slipway cylinder is that: the slip table cylinder during operation is more stable, is difficult to take place the shake.
