Technical Field

The utility model relates to auxiliary equipment for assembling a silencer, in particular to a bolt tightening mechanism for assembling a silencer.

Background

The muffler is assembled to the engine by a plurality of bolts, and the prior art operation is to complete the assembly of the muffler by an installer tightening each bolt in turn using an automatic bolt tightening mechanism. However, such an operation mode causes the installer to repeat the operation for many times, which is not favorable for improving the production efficiency.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a bolt tightening mechanism capable of improving the assembling efficiency of a silencer.

In order to achieve the purpose, the basic scheme of the utility model provides a bolt tightening mechanism for assembling a silencer, which comprises a rack, wherein a driving gear is rotatably connected to the rack, driven gears are symmetrically arranged on two sides of the driving gear and are meshed with the driving gear, a driving shaft which is coaxially and statically connected with the driving gear is arranged on one side of the rack, a driving sleeve is statically connected to one end, away from the driving gear, of the driving shaft, a driven shaft which is coaxially and statically connected with the driven gear is arranged on the other side of the rack, and a driven sleeve is statically connected to one end, away from the driven gear, of the driven shaft.

The beneficial effect of this basic scheme lies in: by adopting the arrangement, when the silencer is installed, the two driven sleeves can be simultaneously screwed by the two bolts on the silencer, so that the assembly efficiency of the silencer is improved.

Further, the frame includes first shell of slot-like and second shell, first shell and second shell lock form the airtight chamber that holds driving gear and driven gear. Adopt such setting, make the frame utilize to hold the chamber and surround driving gear and driven gear, avoided debris to get into between driving gear and the driven gear and influence the transmission, also can avoid operating personnel mistake to touch driving gear or driven gear and be injured simultaneously, improved security and reliability.

Furthermore, the rack is fixedly connected with copper sleeves which are respectively matched with the driving shaft and the driven shaft in a rotating way. By adopting the arrangement, the stability of the driving shaft and the driven shaft in rotation can be enhanced.

Further, the driving shaft is in flat key connection with the driving gear. By adopting the arrangement, the driving gear is in running fit with the rack through the driving shaft, so that the driving gear is not required to be separately connected with the rack, and the structure is simplified.

Further, the driven shaft is in flat key connection with the driven gear. By adopting the arrangement, the driven gear is in running fit with the rack through the driven shaft, so that the driven gear is not required to be separately connected with the rack, and the structure is simplified.

Furthermore, the driving sleeve is matched with the driving shaft hole and is in pin joint with the driving shaft hole. By adopting the arrangement, the driving sleeve is convenient to replace.

Further, the driven sleeve is matched with the driven shaft hole and is in pin joint with the driven shaft hole. By adopting the arrangement, the driven sleeve can be replaced conveniently.

Drawings

Fig. 1 is an exploded view of a structure of an embodiment of a bolt tightening mechanism for assembling a muffler according to the present invention.

Detailed Description

The following is further detailed by way of specific embodiments:

reference numerals in the drawings of the specification include: the driving sleeve comprises a driving sleeve 1, an inner hexagon bolt 2, a first shell 3, a copper sleeve 4, a driving shaft 5, a driven shaft 6, a second shell 7 and a driven sleeve 8.

The embodiment is basically as shown in the attached figure 1: the utility model provides a silencer assembly is with bolt tightening mechanism, includes the frame, and in this embodiment, the frame includes grooved first shell 3 and second shell 7, and first shell 3 and the 7 lock of second shell form a airtight chamber that holds, adopt hexagon socket head cap screw 2 to connect fixedly between first shell 3 and the second shell 7. The middle part that holds the chamber of frame is provided with the driving gear, and the both sides of driving gear set up the symmetry and are provided with driven gear, and driving gear and driven gear set up side by side along the length direction of frame. The driving gear is statically connected with a driving shaft 5, in the embodiment, one end of the driving shaft 5 is preferably connected with the driving gear through a flat key, the other end of the driving shaft 5 extends out of the outer side of the first shell 3, and the first shell 3 is nested with a copper sleeve 4 which is in running fit with the driving shaft 5. The one end static connection that driving shaft 5 kept away from the driving gear has initiative sleeve 1, and in this embodiment, initiative sleeve 1 adopts the shape hole cooperation with driving shaft 5, for example sets up the rectangular hole on initiative sleeve 1, sets up the rectangle section with the unsmooth complex of rectangular hole at the tip of driving shaft 5, utilizes the rectangle section to insert in the rectangular hole and realize connecting to adopt the round pin to wear to establish on driving shaft 5 and initiative sleeve 1 along radial simultaneously, realize driving shaft 5 and initiative sleeve 1's pin joint. The driven gear is connected with a driven shaft 6 in a static mode, in the embodiment, one end of the driven shaft 6 is preferably connected with the driven gear through a flat key, the other end of the driven shaft 6 extends out of the second shell 7, and a copper sleeve 4 in running fit with the driven shaft 6 is nested on the second shell 7. Driven shaft 6 keeps away from driven gear's one end static connection has driven sleeve 8, and in this embodiment, driven sleeve 8 adopts the hole cooperation with driven shaft 6, for example sets up the rectangular hole on driven sleeve 8, sets up the rectangle section with the unsmooth complex of rectangular hole at the tip of driven shaft 6, utilizes the rectangle section to insert in the rectangular hole and realize connecting to adopt the round pin to wear to establish on driven shaft 6 and driven sleeve 8 along radial simultaneously, realize driven shaft 6 and driven sleeve 8's pin joint.

The specific implementation process is as follows: when the silencer is assembled, the two driven sleeves 8 are sleeved on the two bolts of the silencer, the driving shaft 5 is driven to rotate through the driving sleeve 1 by utilizing the driving equipment (such as a pneumatic gun) arranged outside, so that the driving shaft 5 sequentially passes through the driving gear, the driven gear and the driven shaft 6 to drive the driven sleeves 8 to rotate, the two bolts are synchronously screwed, and the assembling efficiency of the silencer is improved.

The foregoing is merely an example of the present invention and common general knowledge of known specific structures and features of the embodiments is not described herein in any greater detail. It should be noted that, for those skilled in the art, without departing from the structure of the present invention, several changes and modifications can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicability of the patent.
