The utility model discloses a fascia gun capable of self-adjusting center, which comprises: an eccentric block; the first end of the connecting rod is connected to the eccentric block; a piston; the positioning sleeve is connected with the piston, the motor is connected with the eccentric block and used for driving the connecting rod to swing to drive the piston to reciprocate, the piston sleeve is arranged at the second end of the connecting rod in a sleeved mode and is in clearance fit with the second end of the connecting rod, the piston is connected with the connecting rod through a piston pin, and the connecting rod can float on the piston pin during operation. Through set up the locating hole on the piston, pass locating hole and connecting rod with the piston pin, the piston pin keeps clearance fit with the connecting rod, adopts interference fit between piston and the piston pin, and overall structure is simple, greatly reduced the processing degree of difficulty, on realizing the same function, can not be because of noise and vibrations that connecting rod and piston do not produce at same center.
Description
Technical Field
The utility model relates to the field of fascia guns, in particular to a fascia gun capable of self-adjusting center.
Background
What traditional manadesma rifle inside piston structure adopted on the market at present is the biasing structure, and when this structural processing locating hole and location end, the precision and the action tolerance of ruler are difficult to guarantee, increase the degree of difficulty of processing, what adopt in the middle of piston and the connecting rod is the bearing connection to die with the screw pressure, can not adjust the center like this, produce noise and vibrations easily, influence the operation and experience.
Disclosure of Invention
Aiming at the defects of the prior art, the utility model provides the fascia gun capable of self-adjusting the center, which can effectively solve the problems of the traditional fascia gun, has a simple integral structure, greatly reduces the processing difficulty, and can not generate noise and vibration because a connecting rod and a piston are not positioned at the same center on the aspect of realizing the same function.
The technical scheme adopted by the utility model for solving the technical problems is as follows: a self-centering fascial gun comprising: an eccentric block; the first end of the connecting rod is connected to the eccentric block; a piston; the piston is sleeved at the second end of the connecting rod and is in clearance fit with the connecting rod, the piston is connected with the connecting rod through a piston pin, and the connecting rod can float on the piston pin during operation.
In the above technical solution, further, the piston is provided with positioning holes, and the positioning holes are located at the upper end and the lower end of the piston.
In the above technical solution, further, the connecting engagement between the connecting rod and the piston pin is a clearance fit.
In the above technical solution, further, an interference fit or a thread fit is provided between the piston pin and the piston.
The utility model has the beneficial effects that: through set up the locating hole on the piston, pass locating hole and connecting rod with the piston pin, the piston pin keeps clearance fit with the connecting rod, adopts interference fit between piston and the piston pin, and overall structure is simple, greatly reduced the processing degree of difficulty, on realizing the same function, can not be because of noise and vibrations that connecting rod and piston do not produce at same center.

The utility model is further illustrated with reference to the following figures and examples.
Fig. 1 is a perspective view of the present invention.
Fig. 2 is a left side view of the present invention.
Fig. 3 is a sectional view taken along line a-a of fig. 3 according to the present invention.
In the figure, 1 is a motor, 2 is an eccentric block, 3 is a connecting rod, 4 is a piston, 5 is a positioning hole, and 6 is a piston pin.
Detailed Description
Referring to fig. 1-3, a self-centering fascial gun, comprising: an eccentric block 2; a first end of the connecting rod 3 is connected to the eccentric block 2; a piston 4; the positioning sleeve is connected with the piston 4, the motor 1 is connected with the eccentric block 2 and used for driving the connecting rod 3 to swing so as to drive the piston 4 to reciprocate, the piston 4 is sleeved at the second end of the connecting rod 3 and is in clearance fit with the second end of the connecting rod 3, the piston 4 is connected with the connecting rod 3 through a piston pin 6, and the connecting rod 3 can float on the piston pin 6 during operation.
Wherein, the piston 4 is provided with positioning holes 5, the positioning holes 5 are arranged on the upper end surface and the lower end surface of the piston 4, the second end of the connecting rod 3 is embedded into the piston 4, and the central hole on the second end of the connecting rod 3 and the positioning holes 5 on the piston 4 are kept on the same vertical line.
In order to ensure the connection between the connecting rod 3 and the piston 4, the wrist pin 6 and the piston 4 are in interference fit or threaded fit, preferably, are in threaded fit, matching threads are arranged on the upper end and the lower end of the wrist pin 6, which are in contact with the piston 4, the threads on the upper end of the piston 4 are through threads, and the threads on the lower end of the piston are non-through threads, so that the wrist pin 6 cannot completely penetrate through the piston 4.
In order to ensure that the connecting rod 3 can realize self adjustment of up-and-down floating on the piston pin 6, the diameter of the middle part of the piston pin 6 is smaller than that of the second end center hole of the connecting rod 3, and the piston pin 6 and the second end center hole of the connecting rod 3 are ensured to be in clearance fit.
The working process of the utility model is as follows: the motor 1 drives the eccentric block 2 to rotate, and the eccentric block 2 synchronously swings with the first end of the connecting rod 3, so that the second end of the connecting rod 3 embedded into the piston pin 6 floats up and down on the cylinder of the piston pin 6 to perform self-centering.
The above description is only an embodiment of the present invention, and is not intended to limit the present invention in any way, and simple modifications, equivalent changes and modifications may be made without departing from the technical scope of the present invention.
