Detailed Description

The utility model discloses the technical problem that will solve is: the existing clamp bench can only translate the workpiece on a horizontal plane and cannot rotate the workpiece. The utility model discloses the technical thinking that just this technical problem provided is: the bearing is jacked up through the cam structure, the clamp is jacked up, and the rotation of the clamp is realized through the bearing.

In order to make the objects, technical solutions and technical effects of the present invention clearer, the following will describe embodiments of the present invention in further detail with reference to the accompanying drawings.

As shown in fig. 1-2, fig. 1 is a schematic structural diagram of a clamp platform according to a preferred embodiment of the present invention; fig. 2 shows a schematic view of the other direction of the bench shown in fig. 1. Specifically, the bench comprises a base 1, wherein a first accommodating cavity 100 is formed in the top of the base 1, and a first through hole 101 penetrating through the first accommodating cavity 100 is formed in the side of the base 1;

the bench further comprises a first bearing seat 3 accommodated in the first accommodation cavity 100; a second through hole 300 is formed in the side of the first bearing seat 3, and a special-shaped cavity 301 which is communicated with the second through hole 300 and is provided with a clamping groove 302 is further formed in the first bearing seat 3;

the clamp platform also comprises a rocker 5 sequentially arranged in the first through hole 101 and the second through hole 300 in a penetrating manner and a cam 18 fixedly sleeved on the rocker 5 and accommodated in the special-shaped cavity 301; the cam 18 is used for rotating along with the rotation of the rocker 5 and is clamped in the clamping groove 302 to drive the first bearing seat 3 to move up and down;

the bench further comprises a first bearing 16 mounted on top of the first bearing block 3, and a clamp detachably supported on the base 1 and liftable by the first bearing 16 for clamping a workpiece (not shown in the figure).

In the above solution, the clamp is normally supported on the base 1 and is not rotatable. When the rocker 5 rotates, the rotation of the cam 18 is converted into upward movement of the first bearing seat 3 and the first bearing 16, and the first bearing 16 further jacks up the clamp, and at the same time, the clamp can rotate relative to the first bearing seat 3 through the first bearing 16. In particular, in this solution, the cam 18 is fixedly mounted on the rocker 5 by means of a first fixing screw 17. Meanwhile, a handle 6 is fixedly installed on the rocker 5 so as to rotate the rocker 5.

Further, the base 1 is formed with a contact surface 102 that is in shape fit with the second bearing housing 7 at the edge of the opening of the first accommodating chamber 100, and by providing the contact surface 102, the contact area between the second bearing housing 7 and the base 1 can be increased. The outer surface of the second bearing seat 7 is spherical, and the contact surface 102 is a cambered surface.

Further, the clamp includes a second bearing seat 7 detachably supported on the base 1 and being capable of being jacked up by a first bearing 16, a clamp block seat 13 rotatably mounted on the second bearing seat 7 through a second bearing 8, and a first locking screw 14 mounted on the second bearing seat 7 for limiting relative rotation between the clamp block seat 13 and the second bearing seat 7.

Here, the second bearing 8 allows relative rotation between the clamping block holder 13 and the second bearing holder 7. By rotating the first locking screw 14, the first locking screw 14 abuts against the clamp block seat 13, so that the relative rotation between the clamp block seat 13 and the second bearing seat 7 is limited by friction.

Specifically, a second accommodating cavity 700 is formed at the top of the second bearing seat 7, and the second bearing 8 is arranged in the second accommodating cavity 700 and is locked and mounted on the second bearing seat 7 through a second locking screw 15; a first locking screw 14 is threadedly mounted on the side of the second bearing block 7.

Furthermore, the top of the clamping block seat 13 is provided with a guide groove 131, the clamp further comprises a positioning support 10 arranged in the middle of the guide groove 131 and fixedly connected with the clamping block seat 13, a first clamping block 20 and a second clamping block 21 arranged in the guide groove 131 and respectively arranged at two sides of the positioning support 10, and a bidirectional screw 22 rotatably penetrating through the positioning support 10 and respectively in threaded connection with the first clamping block 20 and the second clamping block 21; the screw threads of the screw portions of the two-way screw 22 connected to the first and

second blocks

20 and 21, respectively, are opposite in direction.

Here, since the sides of the first and

second clamping blocks

20 and 21 are restricted by the guide groove 131, when the bidirectional screw 22 rotates, the first and

second clamping blocks

20 and 21 move along the guide groove 131; and because the screw thread directions of the screw thread parts of the two-way screw 22 connected with the first clamping block 20 and the second clamping block 21 are opposite, the first clamping block 20 and the second clamping block 21 move in the opposite direction or in the opposite direction along with the rotation of the two-way screw 22, so that the clamping or the loosening of the workpiece by the clamp is realized.

Specifically, here, the bottom portion of the positioning bracket 10 is fixedly connected to the block holder 13 by the second fixing screw 11, the third fixing screw 12, and the fourth fixing screw 9, respectively.

Meanwhile, a bidirectional screw cap 19 is fixedly mounted on the bidirectional screw 22, and the bidirectional screw 22 can be conveniently rotated through the bidirectional screw cap 19.

Furthermore, the bench also comprises a support sleeve 4 arranged in the first accommodating cavity 100, the support sleeve 4 is freely placed on the base 1 in a clearance manner, and the rocker 5 is fixed on the support sleeve 4 through a fifth fixing screw 2; the first bearing housing 3 is relatively slidably disposed in the support sleeve 4.

The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
