[0002] A linear motor is a transmission device that converts electrical energy directly into linear motion mechanical energy without any intermediate conversion mechanism. Usually after the linear motor is assembled, in order to better fix the components together, people generally use electric welding guns to weld the components, thereby improving the stability of the linear motor and making it safer for people to use.

[0003] At present, when most people weld linear motors, in order to prevent the positions where spot welding of the linear motors is required to be shaken, they usually use both hands to manually fix the positions where spot welding of the linear motors is required, and then weld the components with an electric welding gun. Since the above method is used to manually fix the positions where spot welding of the linear motors is required, the linear motors are easy to get loose. In addition, since the entire device of the linear motor is relatively long, if the other end of the linear motor is not pressed down, the other end of the linear motor is easy to deviate from the position where spot welding is required when it moves.

DETAILED DESCRIPTION

[0032] The present invention is further described below with reference to the accompanying drawings, and embodiments of the present invention are given with reference to the accompanying drawings.

[0033] Example 1

[0034] An auxiliary spot welding device for linear motor manufacturing includes a mounting frame 1, a support frame 2, a rotating wheel 3, an extrusion mechanism 4, a clamping mechanism 5 and a pushing mechanism 6, see Figure 1-Figure 6 As shown, a support frame 2 is welded on the upper part of the mounting frame 1, and three rotating wheels 3 are rotatably provided at intervals on the inner side of the support frame 2. Under the action of the rotating wheels 3, the linear motor can be assisted to move. An extrusion mechanism 4 is provided on the right side of the top of the support frame 2, a clamping mechanism 5 is provided on the left side of the support frame 2, and a pushing mechanism 6 is provided on the upper left side of the support frame 2.

[0035] The squeezing mechanism 4 includes a guide rod 40, a sliding rod 41, a first elastic member 42 and a rubber wheel 43, see Figure 3 As shown, guide rods 40 are welded on both the front and rear sides of the right side of the top of the support frame 2, a sliding rod 41 is slidably provided between the lower sides of the two guide rods 40, and a first elastic member 42 is connected between the upper sides of the two guide rods 40 and the sliding rod 41. The first elastic member 42 is an extrusion spring, and a rubber wheel 43 is rotatably provided on the sliding rod 41. The rubber wheel 43 contacts the linear motor, so that the rubber wheel 43 can press the linear motor.

[0036] The clamping mechanism 5 includes a connecting frame 50, a guide plate 51, a toggle rod 52, a rotating plate 53 and a clamping block 54. Figure 4 and Figure 5As shown, connecting frames 50 are welded to the left parts of the front and rear sides of the support frame 2, and guide plates 51 are connected to the upper right parts of the two connecting frames 50. The outer sides of the two guide plates 51 are rotatably provided with toggle rods 52, and the inner sides of the tops of the two toggle rods 52 are rotatably provided with rotating plates 53. The inner sides of the two guide plates 51 are slidably provided with clamping blocks 54, which contact with the linear motor through the clamping blocks 54 and can clamp the linear motor. The front clamping block 54 is rotatably connected to the front rotating plate 53, and the rear clamping block 54 is rotatably connected to the rear rotating plate 53.

[0037] The push mechanism 6 includes a mounting plate 60, an electric push rod 61, a push frame 62 and a connecting plate 63, see Figure 6 As shown, a mounting plate 60 is connected to the upper left portion of the support frame 2, and an electric push rod 61 is bolted to the middle portion of the mounting plate 60. The electric push rod 61 provides power to move the clamping block 54. A pushing frame 62 is connected to the telescopic rod of the electric push rod 61. Connecting plates 63 are connected to the front and rear sides of the upper right portion of the pushing frame 62. The front connecting plate 63 is rotatably connected to the front toggle rod 52, and the rear connecting plate 63 is rotatably connected to the rear toggle rod 52.

[0038] When people need to use the linear motor to manufacture auxiliary spot welding equipment, they first pull the rubber wheel 43 upward to move it, thereby driving the sliding rod 41 to move upward, compressing the first elastic member 42, and then placing the linear motor on the support frame 2 so that the linear motor contacts the rotating wheel 3, and then release the rubber wheel 43. Under the elastic force of the first elastic member 42, the sliding rod 41 and the rubber wheel 43 move downward. When the rubber wheel 43 contacts the linear motor, the rubber wheel 43 will press the linear motor, and then turn on the electric push rod 61 to control the telescopic rod of the electric push rod 61 to shorten, thereby driving the push frame 62 and the connecting plate 63 to move to the right, so that the connecting plate 63 squeezes the toggle rod 52 to rotate. The linear motor 50 is moved to the left, thereby driving the rotating plate 53 to rotate, so that the rotating plate 53 pulls the clamping block 54 to move outward, and then pushes the linear motor to move to the left, so that the left end of the linear motor moves between the clamping blocks 54. During this period, the rotating wheel 3 and the rubber wheel 43 will rotate, thereby assisting the linear motor to move, and then the telescopic rod of the electric push rod 61 is controlled to extend, thereby driving the pushing frame 62 and the connecting plate 63 to move to the left, so that the connecting plate 63 pulls the toggle rod 52 to reverse, thereby driving the rotating plate 53 to reverse, so that the rotating plate 53 squeezes the clamping block 54 to move inward, and when the clamping block 54 contacts the linear motor, the clamping block 54 clamps the linear motor, thereby fixing the linear motor, and then Turn off the electric push rod 61, and then people can spot weld the left end of the linear motor. When the spot welding of the left end of the linear motor is completed, turn on the electric push rod 61 again, control the telescopic rod of the electric push rod 61 to shorten, and move the clamping block 54 outward, so that the clamping block 54 releases the linear motor, and then turn off the electric push rod 61, and then push the linear motor to the left for a distance, and then repeat the above operation, the left half of the linear motor can be spot welded. When the spot welding of the left half of the linear motor is completed, pull the rubber wheel 43 upward again, thereby driving the sliding rod 41 to move upward, so that the rubber wheel 43 is separated from the linear motor, so that the rubber wheel 43 is loosened. The linear motor is then removed from the support frame 2, and the rubber wheel 43 is loosened. The first elastic member 42 returns to its original state, and the first elastic member 42 drives the sliding rod 41 and the rubber wheel 43 to move downward and reset. Then the electric push rod 61 is turned on again, and the telescopic rod of the electric push rod 61 is controlled to extend, thereby driving the pushing frame 62 and the connecting plate 63 to move to the left, so that the connecting plate 63 pulls the toggle rod 52 to reverse and reset, thereby driving the rotating plate 53 to reverse and reset, so that the rotating plate 53 squeezes the clamping block 54 to move inward and reset, and then the electric push rod 61 is closed, and the above operation is repeated, and the right half of the linear motor can be spot welded, thereby spot welding the entire linear motor.

[0039] Example 2

[0040] On the basis of embodiment 1, a rotating mechanism 7 is also included. The rotating mechanism 7 includes a connecting rod 70, a rotating shaft 71, a threaded shaft 72, a screw disk 73 and a second elastic member 74. Figure 1 , Figure 7 , Figure 8 and Fig. 9 As shown, a connecting rod 70 is rotatably provided between the lower front parts of the left and middle rotating wheels 3, and a connecting rod 70 is also rotatably provided between the lower rear parts of the right and middle rotating wheels 3. The rotating wheels 3 are driven to rotate by the connecting rod 70, so that the rotating wheels 3 can drive the linear motor to move. The rear side of the inner part of the rotating wheel 3 on the left is connected to a rotating shaft 71 through a one-way clutch, and a threaded shaft 72 is connected to the rear side of the rotating shaft 71. A screw disk 73 is threaded on the screw shaft 72, and the screw disk 73 is slidably connected to the connecting frame 50 on the rear side. The clamping block 54 on the rear side will contact the screw disk 73 when it moves to the rear side. A second elastic member 74 is connected between the rear left part of the screw disk 73 and the connecting frame 50 on the rear side, and the second elastic member 74 is a reset spring.

[0041] When the clamping block 54 moves outward, the clamping block 54 at the rear side will contact the screw disk 73. At this time, the clamping block 54 at the rear side will squeeze the screw disk 73 to move backward, and the second elastic member 74 will be compressed, so that the screw disk 73 drives the threaded shaft 72 and the rotating shaft 71 to rotate. At this time, the rotating shaft 71 drives the rotating wheel 3 on the left to rotate, thereby driving the rotating wheels 3 in the middle and right sides to rotate through the connecting rod 70, so that the rotating wheel 3 drives the linear motor to move to the left, thereby replacing the manual push of the linear motor to move to the left. When the clamping block 54 moves inward, the clamping block 54 at the rear side will contact the screw disk 73. At this time, the second elastic member 74 is compressed, so that the screw disk 73 drives the threaded shaft 72 and the rotating shaft 71 to rotate. At this time, the rotating shaft 71 drives the rotating wheel 3 on the left to rotate. 3, at this time, under the elastic force of the second elastic member 74, the screw disk 73 moves forward, so that the screw disk 73 contacts the clamping block 54 at the rear side, and then the screw disk 73 drives the threaded shaft 72 and the rotating shaft 71 to reverse, at this time the rotating shaft 71 does not drive the left rotating wheel 3 to reverse, when the clamping block 54 moves inward to reset, the clamping block 54 at the rear side will separate from the screw disk 73, at this time the second elastic member 74 returns to its original state, and the second elastic member 74 drives the screw disk 73 to move forward to reset, so that the screw disk 73 drives the threaded shaft 72 and the rotating shaft 71 to reverse and reset.

[0042] The protective mechanism 8 includes a metal hose 80 and a protective cover 81. Figure 1 and Fig.10 As shown, a metal hose 80 is connected to the rear side of the lower part of the front connecting frame 50, and a protective cover 81 is connected to the other end of the metal hose 80. With the help of the protective cover 81, people's faces can be protected.

[0043] When people need to spot weld the linear motor, they can twist the metal hose 80 to drive the protective cover 81 to move, and then adjust the position of the protective cover 81. After adjustment, loosen the metal hose 80, and then people can spot weld the linear motor using the protective cover 81, during which the protective cover 81 can protect people's faces.

[0044] The device also includes an exhaust mechanism 9, which includes a support ring 90, a fan 91 and a filter screen 92. Figure 1 and Fig.11 As shown, support rings 90 are connected to the inner sides of the tops of the two guide plates 51, and fans 91 are bolted to the middle parts of the upper sides of the two support rings 90. When the fans 91 are turned on, harmful gases generated during spot welding of the linear motor can be dispersed outwards, and filter screens 92 are connected to the upper inner parts of the two support rings 90.

[0045] When people are spot welding the linear motor, they can turn on the fan 91 so that the fan 91 can disperse the harmful gas generated during the spot welding of the linear motor through the filter 92 to the outside, thereby preventing people from inhaling too much harmful gas. When the spot welding of the linear motor is completed, the fan 91 can be turned off.

[0046] While the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that many changes, modifications, substitutions and alterations may be made to the embodiments without departing from the principles and spirit of the invention.
