Description

Technical Field

[0001] The utility model belongs to the technical field of workpiece connection tool equipment, in particular to a screw driving gun. Background Art

[0002] During the assembly process of the distribution cabinet, a large number of screws are usually used for locking connections. When operating, the worker puts the screws into the screwing position of the workpiece with one hand, and holds the screwing gun with the other hand, and uses the electric screwing gun to automatically screw them in.

[0003] However, before screwing in, the worker inserts the lower end of the screw into the screwing position of the workpiece and adjusts the output end of the screwing gun to keep the axes of the screwing gun, the screw and the screwing position of the workpiece consistent, so as to avoid the screw from being skewed when being screwed in, affecting the connection effect, or damaging the cabinet body of the distribution cabinet and affecting the quality of the distribution cabinet. In this process, in order to keep the axes of the screwing gun, the screw and the screwing position of the workpiece consistent, the worker stops and observes after screwing in a certain distance. If the position is skewed, the screw needs to be withdrawn and screwed in again, which leads to low work efficiency. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a screw driving gun, which can keep the screw coaxial with the driving gun before being screwed in. During operation, it is only necessary to make the axis of the screw coaxial with the screwing position of the workpiece, thereby improving operating efficiency.

[0005] In order to achieve the purpose of this utility model, the following scheme is proposed:

[0006] A screw driving gun, comprising:

[0007] The gun body has a drill gun at the bottom of one end and connecting rings on both sides of one end of the gun body;

[0008] The holster assembly includes a sleeve that is sleeved outside the drill gun, with connecting rods provided at both ends of the top of the sleeve, which are slidably connected to the connecting ring. A avoidance hole is vertically opened on one side of the outer wall of the sleeve, and a screw guide is provided in the avoidance hole. One end of the screw guide is hinged to the sleeve, and L-shaped baffles are provided in a circular array at the bottom of the sleeve. The vertical part of the L-shaped baffle is hinged to the outer wall of the sleeve, and the horizontal part faces the axis of the sleeve.

[0009] Furthermore, support ears are respectively provided on both sides of the top of the sleeve, and the lower end of the connecting rod is connected to the support ears.

[0010] Furthermore, a spring is provided on the outer sleeve of the drill gun, and two ends of the spring are respectively in contact with the gun body and the sleeve.

[0011] Furthermore, a group of spaced support plates are symmetrically provided on the outer wall in the middle of the sleeve, one group of support plates corresponds to the top of the avoidance hole, connecting pins are respectively provided on both sides of the screw guide tube, the connecting pins are hinged to the support plates, and a first tension spring is provided between one group of support plates and the avoidance hole, and the two ends of the first tension spring are respectively connected to the sleeve and the screw guide tube.

[0012] Furthermore, a connecting seat is provided in a circular array at the bottom of the sleeve, and the vertical part of the L-shaped baffle is rotatably connected to the connecting seat.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the implementation methods of the present invention are described in detail below with reference to the accompanying drawings. However, the embodiments described in the present invention are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] like Figure 1-Figure 5 As shown, this embodiment provides a screw-in gun, comprising a gun body 10 and a holster assembly 20 .

[0024] Specifically, such as Figure 1 As shown, a drill gun 11 is provided at the bottom of the front end of the gun body 10, and connecting rings 12 are provided at the bottoms on both sides so as to extend outwards.

[0025] The holster assembly 20 includes a sleeve 21, a connecting rod 22, a screw guide tube 24, and an L-shaped baffle 25. The sleeve 21 is vertically sleeved on the outer wall of the drill gun 11. Both sides of the top of the sleeve 21 are respectively provided with support ears 221 extending outward. The lower end of the connecting rod 22 is connected to the top surface of the support ear 221, and the upper end is vertically upwardly penetrated into the connecting ring 12. A limit plate is provided at the upper end of the connecting rod 22, and the connecting rod 22 is slidably connected to the connecting ring 12.

[0026] An avoidance hole 23 is vertically provided on one side of the outer wall of the sleeve 21. The avoidance hole 23 is a strip-shaped structure. The lower end of the screw guide tube 24 is passed through the avoidance hole 23. A group of spaced support plates 212 are provided on the outer wall of the sleeve 21. Both sides of the upper end of the screw guide tube 24 are respectively connected with connecting pins, and the connecting pins are rotatably connected to a group of support plates 212. A first tension spring 213 is provided between the upper end of the avoidance hole 23 and a group of support plates 212. One end of the first tension spring 213 is connected to the outer wall of the screw guide tube 24, so that the lower end of the screw guide tube 24 remains extended into the sleeve 21 in the absence of external force, thereby guiding the screw to automatically enter the sleeve 21 in a vertical state along the lower end of the screw guide tube 24.

[0027] like Figure 3-Figure 5 As shown, the lower end of the sleeve 21 is provided with a connecting seat 214 in a circumferential array, and the upper end of the vertical part of the L-shaped baffle 25 is rotatably connected to the connecting seat 214. An annular sleeve 215 is protruding from the center of the lower end of the sleeve 21. The outer diameter of the annular sleeve 215 is smaller than the outer diameter of the sleeve 21, and the inner diameter is consistent with the inner diameter of the sleeve 21. The horizontal part of the L-shaped baffle 25 extends a predetermined length toward the inner wall of the annular sleeve 215 in the direction of the axis of the inner annular sleeve 215, so that the horizontal part of the L-shaped baffle 25 is used to limit the nut of the screw. The outer wall of the annular sleeve 215 is provided with a second tension spring 216 in a circumferential array. The number of the second tension springs 216 is consistent with the number of the L-shaped baffles 25, and the outer end of the second tension spring 216 is connected to the inner wall of the vertical part of the L-shaped baffle 25.

[0028] An upper end of the inner wall of the transverse portion of the L-shaped retaining bar 25 is provided with an inclined surface 251 to facilitate the screw to escape from the restriction of the L-shaped retaining bar 25 when being screwed into the workpiece.

[0029] Specific operation process:

[0030] The screw-in end of the screw is inserted downward along the upper end of the screw guide tube 24, and the sleeve 21 is pulled upward to make the drill gun 11 vertically downward along the axis of the sleeve 21, and push the screw guide tube 24 to rotate out of the avoidance hole 23. During the rotation process, the lower end of the screw guide tube 24 is away from one side of the sleeve 21 wall, so that the screw automatically falls into the sleeve 21, and the lower end of the screw extends out of the lower end of the horizontal part of the L-shaped stop bar 25, and the nut is limited by the upper end of the horizontal part of the L-shaped stop bar 25. Then the screw is aligned with the screwing position of the workpiece, and at the same time, the drill gun 11 acts vertically downward on the nut at the upper end of the screw, so that the screw is subjected to the downward pre-pressure of the drill gun 11, so that the screw is vertically maintained in the horizontal position of the L-shaped stop bar 25. When the lower end of the screw is inserted into the screwing position of the workpiece, the drill gun 11 is started to make the drill gun 11 screw the screw into the workpiece.

[0031] The above description is only a preferred embodiment of the present invention and does not represent the only embodiment or limit the present invention. It should be understood by those skilled in the art that various changes or equivalent replacements made to the present invention without departing from the scope of the present invention are within the scope of protection of the present invention.
