Description

Conical cam clamp mechanism of extrusion disc

Technical Field

The utility model relates to the technical field of clamping equipment, in particular to a conical cam clamp mechanism of an extrusion disc.

Background

The extrusion dish of extruder need clear up after using a period, in order to thoroughly clear up a plurality of extrusion holes on the basis dish, uses special fixture to fix in the prior art generally and clear up again, and special fixture generally needs to use cylinder or motor and screw's cooperation just can press from both sides tight extrusion dish, and the structure is complicated and with high costs, has the space of improvement.

Disclosure of Invention

Aiming at the defects existing in the prior art, the main purpose of the utility model is to provide a conical cam clamp mechanism of an extruder with simple structure and low cost.

In order to achieve the above purpose, the present utility model provides the following technical solutions: the utility model provides a extrude toper cam anchor clamps mechanism of dish, includes the support, it is connected with the camshaft to rotate through the bearing on the support, be provided with the toper cam through rectangular key on the camshaft, the leg joint has the platform, still be connected with two clamp arms through the pivot rotation on the support, two clamp arm's one end is provided with the clamp block that is located the platform, two clamp arm's the other end is provided with the roll wheel with toper cam roll connection respectively, be provided with the spring fixed column on two clamp arms respectively between pivot and roll wheel, be provided with the spring between two spring fixed column.

Preferably, the support is further connected with an adjusting screw in a threaded manner, an adjusting disc is arranged at the bottom of the adjusting screw, and an annular adjusting groove matched with the adjusting disc is formed in the top of the conical cam.

Preferably, an adjusting handle is arranged at the top of the adjusting screw.

Preferably, a switch handle is arranged at the bottom of the cam shaft.

Compared with the prior art, the utility model has the advantages that the extruding disc needing to be fixed is placed on the platform, the cam shaft is rotated, the cam shaft can drive the conical cam to rotate, and when the conical cam rotates, the rolling wheel in rolling connection with the conical cam can drive the two clamping arms to rotate around the rotating shaft, so that the included angle between the two clamping arms can be changed, and the extruding disc can be clamped or released by the clamping blocks. Wherein the adjusting screw is used for changing the up-and-down position of the conical cam relative to the strip key, so that the included angle between the two clamping arms can be changed each time by changing the up-and-down position of the conical cam. The advantage of this scheme is simple structure, adjusts conveniently.

Drawings

Fig. 1 is a schematic view of the structure of a conical cam clamp mechanism of an extrusion disk of the present utility model.

In the figure: 1. a bracket; 2. a bearing; 3. a cam shaft; 4. a bar key; 5. a tapered cam; 6. a platform; 7. a clamping arm; 8. a clamping block; 9. a rolling wheel; 10. a spring; 11. adjusting a screw; 12. an adjusting disc; 13. an annular adjustment groove; 14. an adjusting handle; 15. a switch handle.

Description of the embodiments

The utility model is further described below with reference to the accompanying drawings.

As shown in fig. 1, a conical cam 5 fixture mechanism of an extrusion disc comprises a support 1, a cam shaft 3 is rotatably connected to the support 1 through a bearing 2, conical cams 5 are arranged on the cam shaft 3 through long keys 4, the support 1 is connected with a platform 6, two clamping arms 7 are rotatably connected to the support 1 through rotating shafts, one ends of the two clamping arms 7 are provided with clamping blocks 8 positioned on the platform 6, the other ends of the two clamping arms 7 are respectively provided with a rolling wheel 9 in rolling connection with the conical cams 5, spring 10 fixing columns are respectively arranged between the rotating shafts and the rolling wheels 9 on the two clamping arms 7, and springs 10 are arranged between the two spring 10 fixing columns.

Preferably, the support 1 is further in threaded connection with an adjusting screw 11, an adjusting disc 12 is arranged at the bottom of the adjusting screw 11, and an annular adjusting groove 13 matched with the adjusting disc 12 is arranged at the top of the conical cam 5.

Preferably, the top of the adjusting screw 11 is provided with an adjusting handle 14.

Preferably, a switch handle 15 is arranged at the bottom of the cam shaft 3. The adjustment handle 14 and the switch handle 15 are provided for facilitating the rotation of the adjustment screw 11 and the cam shaft 3.

The utility model provides a conical cam 5 anchor clamps mechanism of extrusion dish, its theory of operation is, places the extrusion dish that will need fix on platform 6, rotates camshaft 3, and camshaft 3 can drive conical cam 5 and rotate, and when conical cam 5 rotated, the roll wheel 9 with conical cam 5 roll connection can drive two clamp arms 7 and rotate around the pivot, can change the contained angle between two clamp arms 7 like this, can realize that the extrusion dish is pressed from both sides tightly or release by clamp block 8. The adjusting screw 11 is used for changing the up-down position of the conical cam 5 relative to the strip key 4, so that the angle between the two clamping arms 7 can be changed each time due to the change of the up-down position of the conical cam 5, and the adjusting screw can be suitable for fixing foundation discs with various diameters. The advantage of this scheme is simple structure, adjusts conveniently.

The above description is only a preferred embodiment of the present utility model, and the protection scope of the present utility model is not limited to the above examples, and all technical solutions belonging to the concept of the present utility model belong to the protection scope of the present utility model. It should be noted that modifications and adaptations to the present utility model may occur to one skilled in the art without departing from the principles of the present utility model and are intended to be within the scope of the present utility model.
