Description

Clamping device

technical field

The utility model relates to a clamping device, in particular to a clamping device which is convenient for assembly and disassembly.

Background technique

The thimble is a common part on the mold. The fixed end of the thimble is usually provided with a countersunk head. In order to prevent the thimble from rotating, a flat surface is often machined on the countersunk head. Currently, the clamping tool used when processing the flat surface on the countersunk head of the thimble is Wanli. folder.

However, Wanli clips can only be processed on a single piece at a time, which is time-consuming and laborious to use. Therefore, it is urgent to develop a clamping device that is easy to disassemble and can hold thimbles of different diameters, so as to meet the needs of factories to control production costs and fast processing.

Utility model content

The purpose of this utility model is to provide a clamping device which is convenient to disassemble and can clamp columns with different diameters in order to solve the above-mentioned deficiencies in the prior art.

In order to achieve the above purpose, the clamping device provided by the utility model is used for clamping a column, which includes a fixed seat, a body fixedly connected above the fixed seat, and an adjustable pressing member arranged on the body. A V-shaped groove runs through the upper surface of the fixed seat, and a receiving groove runs through the lower surface of the body and faces the V-shaped groove. The pressing part is adjustably arranged on the body, and the pressing part has a pressing end extending into the accommodation groove.

As mentioned above, the clamping device of the utility model clamps columns of different diameters by the V-shaped groove opened on the fixing seat and the pressing piece that can move up and down by screwing, and its disassembly is simple and convenient.

Detailed ways

In order to describe the technical content, structural features, achieved goals and effects of the present utility model in detail, the following will be described in detail in conjunction with the embodiments and accompanying drawings.

Please refer to FIG. 1 , in this embodiment, the clamping device is used to clamp a column with a circular cross section, specifically, the column is a thimble 50 in a molding die (as shown in FIG. 2 ). The clamping device includes a fixed base 10 , a body 20 fixedly connected above the fixed base 10 , an adjustable pressing member 30 disposed on the main body 20 , and a pad 40 fixedly installed on the lower end of the pressing member 30 .

The fixing seat 10 is provided with a V-shaped groove 11 extending forward and backward through the upper surface thereof. A positioning platform 12 protrudes forward from the front surface of the fixing seat 10 . The main body 20 is provided with an accommodating groove 21 extending forward and backward through the lower surface thereof. In this embodiment, the accommodating groove 21 is in an inverted U-shape. After the body 20 is fixed above the fixing base 10 by screws, the accommodating groove 21 faces the V-shaped groove 11 .

The pressing member 30 has a pressing end 31 , which can adjustably pass through the body 20 and extend into the receiving groove 21 , and a screwing portion 32 disposed on the upper end of the pressing end 31 . In this embodiment, the pressing member 30 is a screw, therefore, the pressing end 31 is a screw rod, and the screwing part 32 is a nut.

The pad 40 is made of a metal material whose hardness is slightly smaller than that of the pressing member 30 and the hardness of the thimble 50 (as shown in FIG. 2 ). In this embodiment, the pad 40 is made of copper material. The gasket 40 is in the shape of a cylinder with threads on its inner side, and is screwed to the lower end of the pressing end 31 of the pressing member 30 through threads.

Please refer to Fig. 2 and Fig. 3, when the clamping device of the present invention is used, firstly, the fixed base 10 is fixedly installed on the machine tool; Installed on the body 20, that is, the pressing member 30 is screwed through the body 20 by the pressing end 31 (screw); then, the thimble 50 to be processed is inserted into the V-shaped groove 11, and the countersunk 51 of the thimble 50 The card is placed on the positioning table 12, so that the countersunk head 51 that needs to be processed on the thimble 50 is aligned to facilitate processing; Tighten the thimble 50, so that the countersunk 51 of the thimble 50 and the like can be processed. It is worth noting that during the pressing down of the pressing member 30, since the pad 40 is made of a metal material whose hardness is slightly smaller than that of the pressing member 30 and the thimble 50, it is possible to avoid the pressure on the thimble 50 when the pressing member 30 is screwed. Screw out the scratches. Moreover, by screwing the pressing member 30 up and down, it is possible to clamp columns with different diameters.

As mentioned above, the clamping device of the present invention clamps the column from three directions of the circular section of the column by the V-shaped groove 11 provided on the fixed base 10 and the pressing piece 30 which can move up and down by screwing. And can clamp the pillars of different diameters, and the disassembly and assembly of the fixing seat 10 on the machine base is simple and convenient.
