Description

Technical Field

[0001] The utility model relates to the technical field of fan clutch processing, in particular to an automatic bolt driving machine for a fan clutch. Background Art

[0002] The main function of the silicone oil fan clutch assembly is to dissipate heat from the engine's cooling water tank. When the engine is running, cooling water is pumped into the engine cavity, carrying away the temperature of the engine's surroundings, turning it into hot water and entering the cooling water tank. The cooling water tank is surrounded by heat sinks, and the silicone oil fan clutch assembly is used to dissipate heat from the heat sinks around the cooling water tank, thereby achieving the purpose of cooling the water tank. Since the engine's cooling water circuit is circulating water, that is, hot water from the engine flows into the cooling water tank, is cooled, and then returns to the engine for heat dissipation, the cooling fan's heat dissipation capacity needs to be determined by the temperature of the engine's surroundings.

[0003] During the production and processing stage of the fan clutch, the fan needs to be fixed with bolts. Currently, this is mainly achieved by a bolting machine. Most existing bolting machines are semi-automatic bolting machines. Their disadvantages are that the bolts need to be placed manually, and the bolt tightening mainly relies on an electric gun to select the tightening angle and force. However, employees still need to manually press the electric gun start button and select the appropriate point, which seriously affects work efficiency and may also result in missed bolts. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an automatic bolting machine for a fan clutch, so as to solve the technical problems in the prior art of low bolting efficiency and possible missed bolting of the fan clutch.

[0005] In order to solve the above technical problems, the utility model provides an automatic bolting machine for a fan clutch, comprising a frame, a first moving assembly, a second moving assembly, a vertical displacement mechanism, a bolt gun, a feeder, a distributor and a tooling seat. The tooling seat is connected to the frame and is used to fix the fan clutch. There are two first moving assemblies and both are connected to the frame and are located on the left and right sides of the tooling seat. The first moving assembly is arranged along the front and back direction, and the second moving assembly is mounted on the two first moving assemblies along the left and right directions. The bolt gun is connected to the second moving assembly through the vertical displacement mechanism. The feeder and the distributor are both connected to the frame. The feeder is used to convey bolts to the distributor, and the distributor outputs single bolts for the bolt gun to absorb.

[0006] After adopting the above structure, the utility model provides an automatic bolting machine for a fan clutch with the following advantages: the feeder sends the bolts to the distributor, the distributor outputs a single bolt, the first moving component drives the bolt gun to move forward and backward, the second moving component drives the bolt gun to move left and right, and the vertical displacement mechanism drives the bolt gun to move vertically, so that the bolt gun can absorb the bolts output by the distributor and move them to the bolt hole position of the fan clutch, and the bolt is tightened by the bolt gun to realize fully automatic bolting, which greatly improves the bolting efficiency, and the fully automatic bolting can accurately record the position of the bolt hole and the number of bolts to prevent missed bolting.

[0007] As an improvement, the feeder includes a shell, a material receiving pipe and a pushing cylinder. A channel for the movement of bolts is provided in the shell. The material receiving pipe is connected to the upper end of the shell and is used to receive the bolts delivered by the feeder. The bottom end of the inner cavity of the material receiving pipe is connected to the channel. The upper end of the shell is provided with a bolt removal hole connected to the channel. The pushing cylinder is connected to the shell and is used to push the bolts in the channel to be coaxial with the bolt removal hole. With this structure, the bolts fall into the channel through the material receiving pipe, and then the pushing cylinder pushes the bolts to the bolt removal hole. After that, the bolts can be sucked up by the bolt gun through the bolt removal hole.

[0008] As an improvement, the feeder also includes a fixed cylinder, which is connected to the shell and is used to fix a bolt coaxially arranged with the bolt hole. With this structure, the bolt is fixed by the fixed cylinder so that the position of the bolt at the bolt hole is accurate, ensuring that the bolt gun accurately absorbs the bolt.

[0009] As an improvement, both the pushing cylinder and the fixing cylinder are connected to bolt position sensors; with this structure, the bolt position sensor outputs a signal when the bolt is in place at the bolt hole, so that the bolt gun moves accurately and timely to pick up the bolt.

[0010] As an improvement, the feeder also includes a limit block, which is connected to the upper end of the shell. A V-shaped guide surface is provided on the end face of the limit block close to the bolt hole, and the projection of the V-shaped guide surface is tangent to the bolt hole. With this structure, the V-shaped guide surface plays a guiding role when the bolt gun absorbs the bolt, so that the bolt gun can accurately absorb the bolt and prevent the bolt from shifting relative to the bolt gun and affecting the tightening of the bolt.

[0011] As an improvement, a drop sensor for detecting the passage of a bolt through the receiving pipe is connected to the receiving pipe, and the drop sensor is electrically connected to the pushing cylinder. With this structure, the drop sensor detects the passage of a bolt through the receiving pipe and outputs a signal, so that the pushing cylinder accurately and timely pushes the bolt to the bolt removal hole.

[0012] As an improvement, the tooling seat is slidably arranged on the frame along the front-rear direction; with this structure, the tooling seat can be moved forward and backward to a position away from the bolt gun to facilitate workers to place the fan clutch, thereby improving safety.

[0013] As an improvement, a guide rail is connected to the frame in the front-to-back direction, and the tooling seat is slidably connected to the guide rail through a slider. A driving cylinder is connected to the frame, and the driving cylinder is connected to the tooling seat and drives the tooling seat to move forward and backward. With this structure, the driving cylinder drives the tooling seat forward to place the fan clutch, and then the driving cylinder drives the tooling seat backward to prepare for bolting.

[0020] The following is a detailed description of an automatic bolt driving machine for a fan clutch according to the present invention with reference to the accompanying drawings.

[0021] like Figures 1 to 5 As shown, an automatic bolting machine for a fan clutch comprises a frame 1, a first moving assembly 2, a second moving assembly 3, a vertical displacement mechanism 4, a bolt gun 5, a feeder, a distributor 7 and a tooling seat 8. The tooling seat 8 is connected to the frame 1 and is used to fix the fan clutch. The frame 1 is opened at the front end for a worker to fix the fan clutch. Specifically, Figure 5As shown, the tooling seat 8 is slidably arranged on the frame 1 along the front-to-back direction. The frame 1 is connected with a guide rail 12 along the front-to-back direction. The tooling seat 8 is slidably connected to the guide rail 12 through a slider. The frame 1 is connected with a driving cylinder 13. The driving cylinder 13 is connected to the tooling seat 8 and drives the tooling seat 8 to move forward and backward. The driving cylinder 13 drives the tooling seat 8 to move to the front side so that the worker can fix the fan clutch. Then the driving cylinder 13 drives the tooling seat 8 to move to the rear side to tighten the bolts.

[0022] like Figure 1 As shown, there are two first movable components 2 and both are connected to the frame 1 and located on the left and right sides of the workbench 8. The first movable component 2 is arranged along the front and rear direction, and the second movable component 3 is mounted on the two first movable components 2 along the left and right direction. The bolt gun 5 is connected to the second movable component 3 through the vertical displacement mechanism 4. The first movable component 2 drives the bolt gun 5 to move forward and backward, the second movable component 3 drives the bolt gun 5 to move left and right, and the vertical displacement mechanism 4 drives the bolt gun 5 to move up and down. The first movable component 2, the second movable component 3 and the vertical displacement mechanism 4 are all existing technologies and will not be repeated here.

[0023] like Figure 1 As shown, the feeder and the divider 7 are both connected to the frame 1. The feeder is used to deliver bolts to the divider 7. The divider 7 outputs a single bolt for the bolt gun 5 to absorb. A number of bolts are poured into the feeder, and the feeder blows the bolts from the pipeline to the divider 7 through air pressure. The specific structure of the feeder is existing technology and will not be repeated here.

[0024] like Figure 2As shown, the feeder 7 includes a shell 71, a material receiving pipe 72, a pushing cylinder 73, a fixing cylinder 74 and a limit block 75. A channel for the movement of bolts is provided in the shell 71. The material receiving pipe 72 is connected to the upper end of the shell 71 and is used to receive the bolts transported by the feeder. The bottom end of the inner cavity of the material receiving pipe 72 is connected to the channel. The upper end of the shell 71 is provided with a bolt removal hole 9 connected to the channel. The pushing cylinder 73 is connected to the shell 71 and is used to push the bolts in the channel to be coaxial with the bolt removal hole 9; the fixing cylinder 74 is connected to the shell 71 and is used to fix the bolts coaxially arranged with the bolt removal hole 9. The pushing cylinder 73 and the fixing cylinder 74 are both connected to a bolt position sensor; specifically, the channel is arranged along the front-to-back direction, The pushing cylinder 73 is arranged at the rear end of the shell 71. After the bolt falls into the channel, the pushing cylinder 73 pushes the bolt forward to the front end of the channel. The upper part of the front end of the channel is the bolt hole 9, and the upper end of the bolt is exposed in the bolt hole 9. The bolt gun 5 moves and absorbs the bolt; in addition, the fixing cylinder 74 is arranged at the front end of the shell 71 and fixes the bolt in the left and right directions. Among them, the two bolt position sensors both judge whether the bolt is in place by monitoring the stroke of the pushing cylinder 73 and the fixing cylinder 74. Taking the pushing cylinder 73 as an example, when the pushing cylinder 73 pushes the bolt to move, the piston rod extends. Its bolt position sensor detects that after the piston rod moves to the maximum stroke, it determines that the bolt is located at the bolt hole 9.

[0025] like Figure 2 As shown, the limit block 75 is connected to the upper end of the housing 71, and a V-shaped guide surface 10 is provided on the end surface of the limit block 75 near the bolt hole 9. Figure 3 As shown, the projection of the V-shaped guide surface 10 is tangent to the bolt hole 9, that is, the projections of the two end surfaces of the V-shaped guide surface 10 on the plane where the upper end of the bolt hole 9 is located are tangent to the bolt hole 9. The material receiving pipe 72 is connected to a material drop sensor 11 for detecting the passage of a bolt through the material receiving pipe 72. The material drop sensor 11 is electrically connected to the pushing cylinder 73. The material drop sensor 11 can be an infrared sensor, a proximity switch, etc. The specific structure and working principle of the bolt driver 5 are all prior art and will not be repeated here.

[0026] The feeder sends the bolts to the distributor 7, and the distributor 7 outputs a single bolt. The first moving assembly 2 drives the bolt gun 5 to move forward and backward, the second moving assembly 3 drives the bolt gun 5 to move left and right, and the vertical displacement mechanism 4 drives the bolt gun 5 to move vertically. The bolt gun 5 absorbs the bolts output by the distributor 7 and moves them to the bolt holes of the fan clutch. The bolt gun 5 tightens the bolts, realizing fully automatic bolting, which greatly improves the efficiency of bolting. In addition, the fully automatic bolting can accurately record the position of the bolt holes and the number of bolts to prevent missed bolting. In addition, if Figure 4As shown, the bolt gun 5 in the present invention is also connected to a visual camera 14. The visual camera 14 assists the bolt gun 5 to automatically move to the bolt hole 9 through vision, and after the bolt gun 5 takes the bolt, it uses visual assistance to determine the position where the product needs to be bolted, and performs the bolt tightening operation after the visual judgment is qualified.

[0027] The above describes the implementation mode of the present invention in detail with reference to the accompanying drawings, but the present invention is not limited to the above-mentioned implementation mode. All other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present invention.
