Description

Technical Field

[0001] The utility model relates to the technical field of pinning, in particular to a clamping and fixing device for shaft workpiece pinning equipment. Background Art

[0002] Some workpieces need to be pinned by pinning equipment in some processing requirements. Pinning equipment is a processing equipment that drills pin holes on the workpiece and presses the pin shaft into the pin hole.

[0003] For example, the Chinese patent technology document with announcement number CN219286118U discloses an automatic pinning mechanism for an insulator, which relates to the field of glass insulator processing technology. The mechanism includes a mounting frame, a foot pedal and a controller on one side of the mounting frame. The foot pedal and the controller are electrically connected. A processing table is provided on the mounting frame, and a support plate and a placement and positioning component are provided on the processing table. A pinning component is provided on the support plate, and the pinning component is located above the placement and positioning component.

[0004] In the above technical solution, the workpiece to be pinned is placed on a placement seat, and the positioning groove on the placement seat limits the workpiece. The extrusion block is then driven downward by an electric cylinder, so that the pin shaft pre-placed in the pin hole of the workpiece can be pressed into the pin hole. However, in actual use, it is found that the positioning groove can only limit the workpiece in the radial direction. Therefore, when the pin shaft is pressed into the pin hole of the workpiece, the workpiece is easily affected by external factors and produces axial deviation, thereby affecting the pinning accuracy of the workpiece. Summary of the Invention

[0005] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a clamping and fixing device for a shaft workpiece pinning device, which can stably clamp the workpiece to ensure the pinning accuracy of the workpiece.

[0006] To achieve the above-mentioned objectives, the utility model provides the following technical solutions: a clamping and fixing device for a pinning device for shaft workpieces, comprising a base, the base being provided with a base and a connecting base movable toward the base, a positioning seat being fixed on the base, the positioning seat being provided with a positioning groove adapted to the shaft workpiece, a pressure block being provided above the positioning seat, the pressure block being provided with a pressure groove adapted to the positioning groove, the pressure block being connected to a driving mechanism, the driving mechanism being used to drive the pressure block close to or away from the positioning seat, a horizontally arranged connecting shaft being provided on the connecting seat, a placement seat being mounted on the connecting shaft, the placement seat being provided with a placement groove opposite to the positioning groove, one end of the connecting shaft being connected to a driving motor, the driving motor being used to drive the connecting shaft to rotate.

[0007] The utility model is further configured as follows: the driving mechanism includes a driving cylinder, an extension portion extending upward is provided on the base, a connecting rod is rotatably connected to the extension portion, one end of the connecting rod is fixed to the pressure block, and the other end extends toward the driving cylinder as a connecting end, the driving cylinder is rotatably connected to the extension portion, and the output end of the driving cylinder is rotatably connected to the connecting end.

[0008] The utility model is further configured as follows: a pushing cylinder is fixed on the base, the output end of the pushing cylinder is fixed to the connecting seat, slide rails are symmetrically fixed on the base, a slider is fixed on the bottom of the connecting seat, the slider is coupled to the slide rail, and a sliding fit between the two can be formed.

[0009] The utility model is further configured as follows: the connecting seat is provided with a connecting portion extending outward, the connecting portion is rotatably connected to a supporting wheel, and the supporting wheel is coupled to the rotating shaft.

[0010] The utility model is further configured as follows: a clearance hole and an air hole are provided on both sides of the positioning seat, the clearance hole and the air hole are communicated with the positioning groove respectively, and the air hole is connected to an external air pump through a hose.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] Since the placement seat for placing the shaft workpiece is installed on a movable connecting seat, after the shaft workpiece is placed in the placement groove on the placement seat, the placement seat can be driven to move by the movement of the connecting seat, so that the shaft workpiece in the placement groove can be abutted against the groove of the positioning groove, thereby constituting an axial limit for the workpiece, and then the pressure block is driven to move toward the positioning seat by the driving mechanism, so that the pressure groove and the positioning groove can be made opposite to each other, so as to constitute a radial limit for the shaft workpiece, and then by radially and axially limiting the shaft workpiece, the shaft workpiece can be prevented from being offset when pinning the shaft workpiece. Therefore, the technical problem of the shaft workpiece being easily offset when pinning the shaft workpiece in the prior art is effectively solved, and the workpiece can be stably clamped to ensure the pinning accuracy of the workpiece.

In this way, after the shaft workpiece 200 is placed on the placement groove 71 on the placement seat 7, the movement of the connecting seat 3 can drive the placement seat 7 to move, so that the shaft workpiece 200 in the placement groove 71 can be abutted against the bottom of the positioning groove 41, thereby constituting an axial limit for the workpiece. Subsequently, the pressure block 5 is driven toward the positioning seat 4 by the driving mechanism, so that the pressure groove 51 can be opposite to the positioning groove 41, so as to constitute a radial limit for the shaft workpiece 200. Then, by radially and axially limiting the shaft workpiece 200, the shaft workpiece 200 can be prevented from being offset when pinning the shaft workpiece 200, and the workpiece can be stably clamped to ensure the pinning accuracy of the workpiece.

[0020] In this embodiment, the specific structure of the driving mechanism includes a driving cylinder 91, an upwardly extending extension portion 21 is provided on the base 2, and a connecting rod 92 is rotatably connected to the extension portion 21. One end of the connecting rod 92 is fixed to the pressure block 5, and the other end extends toward the driving cylinder 91 as a connecting end. The driving cylinder 91 is rotatably connected to the extension portion 21, and the output end of the driving cylinder 91 is rotatably connected to the connecting end. The connecting rod 92 can be driven to rotate with the connection with the extension portion 21 as the rotation center through the extension and contraction of the output end of the driving cylinder 91. In this way, the pressure block 5 connected to the connecting rod 92 can be driven toward or away from the positioning seat 4, thereby realizing radial limitation of the shaft workpiece 200.

[0021] In this embodiment, the structure for moving the connecting seat 3 is that a pushing cylinder 10 is further fixed on the base 1, and the output end of the pushing cylinder 10 is fixed to the connecting seat 3. The slide rail 11 is symmetrically fixed on the base 1, and a slider 12 is fixed to the bottom of the connecting seat 3.

[0023] In this embodiment, a clearance hole 42 and an air hole 43 are provided on both sides of the positioning seat 4. The clearance hole 42 and the air hole 43 are respectively connected to the positioning groove 41. The air hole 43 is connected to an external air pump through a hose 100. Through the set clearance hole 42, when punching the shaft workpiece 200, the punching head can contact the shaft workpiece 200 in the positioning groove 41 through the clearance hole 42, thereby completing the punching of the shaft workpiece 200, and the setting of the air hole 43 can be connected to an external air pump through the hose 100. Therefore, after the punching equipment punches the shaft workpiece 200, the external air pump can blow out the debris generated during the punching from the clearance hole 42, thereby facilitating the subsequent punching of the shaft workpiece 200.
