Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the technical scheme in the utility model, all other embodiments that ordinary skilled person in the art obtained under the prerequisite of not making the creative work all belong to the scope of the utility model protection.

Referring to fig. 1 to 2, the present invention provides a technical solution: a spring chuck with a workpiece positioning structure comprises a connecting seat 1, wherein at least four pressing plates 3 which are arranged in a circumferential array and are inclined in a conical surface are integrally formed on the right side of the connecting seat 1, matched inner conical sleeves 12 are sleeved on the outer sides of the pressing plates 3, axial bearings 13 are installed on the right sides of the inner conical sleeves 12, threaded sleeves 11 are installed on the axial bearings 13, the left sides of the threaded sleeves 11 are connected with the connecting seat 1 through threads, and at least three handles 10 which are arranged in a circumferential array are arranged on the outer sides of the threaded sleeves 11;

the tail end of the compression plate 3 is provided with a limiting rod 2, the limiting rod 2 comprises a polygonal rod 202 which is spliced with the compression plate 3, a screw rod 201 is integrally formed on the polygonal rod 202, an adjusting screw button 6 is screwed on the screw rod 201, a matching ring 7 is mounted below the adjusting screw button 6 in a compression mode, a spring 4 is connected between the matching ring 7 and the compression plate 3, a positioning plate 14 used for compressing a workpiece is integrally formed at the tail end of the polygonal rod 202, and a rotating handle 5 is welded on the adjusting screw button 6;

handle 10 and thread bush 11 integrated into one piece or welded mounting, and the inside of handle 10 is seted up and is expanded the centre bore that rotates the handle and match with the outside, it has a locating hole 16 to be the circumference array on the connecting seat 1 every fifteen degrees, and the spiro union is installed and is installed the fixing bolt 9 that matches with locating hole 16 on the thread bush 11, integrated into one piece has the ring gear 8 that matches with external drive motor on the thread bush 11, and the effective cooperation thickness between the drive wheel of ring gear 8 and external drive motor is the twice of the maximum adjustment stroke of thread bush 11, connecting seat 1 passes through bolt and external fixed mounting, and the central point of connecting seat 1 is offered and is used for the cross-section of centering to be hexagonal to interface 15.

The working principle is as follows: when the device is used, a workpiece is firstly inserted and installed between a pair of positioning plates 14, then the workpiece can be pre-clamped at a designated position by manually rotating the position of the workpiece and rotating the upper and lower adjusting screw buttons 6, the pre-clamping process can avoid the situation that the workpiece is subjected to position change again when the spring chuck body is subsequently adjusted, so that the workpiece can be effectively and correctly clamped at the designated position and has the positioning effect, the pre-clamping process is relatively simple to operate, a large amount of labor is not required to be consumed, the threaded sleeve 11 can be directly driven to rotate by the moving handle 10 after the pre-clamping is finished, the threaded sleeve 11 can push the inner taper sleeve 12 to move towards the left in the rotating process, and the inward gathering and pressing of displacement quantity of the pressing plates at each position can be realized by utilizing the inner taper sleeve 11, so that the pressing plates 3 can formally and completely clamp the workpiece, and because the pressure strip 3 does not rotate in the process of furling, and the position of the workpiece is limited by the positioning plate 14, the inward furling process of the pressure strip 3 can gradually increase the clamping force of the positioning plate 14, so that the position of the workpiece cannot be displaced in the clamping process of the pressure strip 3, and the clamping and positioning accuracy of the workpiece can be effectively guaranteed. The device uses easy operation, can press from both sides through two and press from both sides the accurate location that realizes the work piece and press from both sides tightly to ensured the tight precision of clamp to the work piece, made things convenient for the accurate processing to the work piece, the device can also have driving motor complex mode to replace the manual tight process of clamp that carries on the second round through ring gear 8 and outside simultaneously, thereby effectual workman's physical power of having saved has improved the tight efficiency of clamp, has very high practical value.
