[0052] Example 2: The difference between the above example and the present embodiment is that: Figure 2 , Figure 3 and Figure 5As shown, the rotation center of the feeding screw shaft 202 is clamped with a bearing, and a bearing seat 2011 is clamped on the outer wall of the bearing, the bearing seat 2011 is installed on the operation table 101, and the side wall of the bearing seat 2011 and the shell of the driving motor 201 are connected with each other, a guide rod 2023 is transversely installed on the bearing seat 2011, a sliding seat 2022 is slidably arranged on the guide rod 2023, and the bottom of the sliding seat 2022 and the screw sleeve 2021 are connected with each other.

[0053] As shown in Figure 7 , Figure 8 and Figure 10 , in the specific embodiment, a pressing plate 3021 is slidably arranged inside the positioning cover 301, one side of the pressing plate 3021 and one side of the jacking rod 302 are connected with each other, a pressing spring 3022 is sleevedly arranged on the jacking rod 302 inside the positioning cover 301, one end of the pressing spring 3022 is clamped on the pressing plate 3021, and the other end of the pressing spring 3022 is clamped on the inner wall of the positioning cover 301.

[0055] Embodiment 3: different from the above embodiments and the present embodiment is that, as shown in Figure 9 The positioning seat 3072 is installed on the pull rod 307, and the positioning seat 3072 is installed on the side wall of the positioning cover 301. The extrusion plate 3073 is installed on the pull rod 307. The reset spring 3074 is arranged in a sleeved mode on the pull rod 307 between the extrusion plate 3073 and the positioning seat 3072.

The protection cover 3014 is installed on the side wall of the positioning cover 301. When the positioning cover 301 moves, and the pull rod 307 and the protrusion 3076 on the positioning cover 301 are separated, at this time, the reset spring 3074 in the inside pushes the extrusion plate 3073 to have a downward force, thereby driving the pull rod 307 at the bottom to slide downward as a whole, and the position of the swing arm 3075 on the pull rod 307 changes synchronously.

[0056] As shown in Figure 3 , Figure 5 and Figure 6 In the specific embodiment, the strip-shaped sliding groove 2051 is installed on the synchronous support 205. The slide rod 3012 is arranged in a sliding mode on the strip-shaped sliding groove 2051. One side of the slide rod 3012 is installed on the side wall of the positioning cover 301.

The synchronous support 205 can drive the positioning cover 301 to move horizontally, and the positioning cover 301 can also slide on the strip-shaped sliding groove 2051.

[0057] The present application further discloses a welding method of the quartz boat automatic welding equipment.

[0058] Step one: the quartz boat outer frame 400 is placed between the clamping plates 1022 as a whole. The clamping plates 1022 are made to move close to the inside through the bidirectional screw shaft 103, so as to clamp and fix the quartz boat outer frame 400.

[0059] Step two: the reinforcing plate 500 is placed in the clamping groove 3011 of the positioning cover 301. The feeding screw shaft 202 is started to drive the slide sleeve 2021 to slide. The slide sleeve 2021 drives the support arm 203, the electric push rod 204 and the welding gun 2041 to move. The welding gun 2041 welds the quartz boat outer frame 400 at different positions.

[0060] Step three: the positioning cover 301 is moved as a whole by the synchronous support 205, the positioning cover 301 pulls the clamping groove reinforcing plate 500 to move, and the bottom protrusion 3031 finally moves along the displacement groove to the pressing groove, thereby the positioning cover 301 is driven to have a downward force, so that the reinforcing plate 500 on the positioning cover 301 is tightly attached to the quartz boat outer frame 400, and the welding gun 2041 is convenient for welding;

[0061] Step four: in the process of horizontal movement of the positioning cover 301, the bottom pull rod 307 and the protrusion 3076 are separated, at this time the pull rod 307 moves downward to change the position of the swing arm, and the push plate at the end is pulled to move to the center to weld the reinforcing plate 500, so that the reinforcing plate 500 is tightly connected with the positioning cover 301.

[0062] The implementation principle of the quartz boat automatic welding equipment and the method thereof in the embodiment is as follows:

[0063] The operator first needs to place the quartz boat outer frame 400 on the top seat 105, and the four corners of the quartz boat outer frame 400 correspond to the clamping plates 1022, and at this time the support legs 1011 and the non-slip pads 1012 at the bottom of the operation table 101 improve the stability of the equipment.

[0064] Then the operator rotates the handle 1042 to rotate the crank handle 1041, and the non-slip sleeve on the handle 1042 increases the friction force, which is convenient for later rotation. After the crank handle 1041 is rotated, the rotating shaft 104 can be rotated, and the rotating shaft 104 can drive the bidirectional screw shaft 103 to rotate as a whole. At this time, the two clamping plates 1022 on the bidirectional screw shaft 103 slide along the slide rail 1023, and the clamping plates 1022 move inward, and finally the clamping plates 1022 clamp and fix the quartz boat outer frame 400.

[0065] Then the operator places the reinforcing plate 500 in the clamping groove 3011 of the positioning cover 301.

[0066] Then the operator starts the driving motor 201, and the driving motor 201 drives the feed screw shaft 202 to rotate on the bearing seat 2011, so that the friction force is reduced, and the screw sleeve 2021 engaged with the feed screw shaft 202 is limited by the guide rod 2023, so that the screw sleeve 2021 slides at this time, and the positioning cover 301 moves under the action of the synchronous support 205.

[0067] When the positioning cover 301 moves, and the pull rod 307 and the protrusion 3076 on the positioning cover 301 are separated, at this time the reset spring 3074 in the inside pushes the extrusion plate 3073 to have a downward force, further drives the bottom pull rod 307 to slide downward as a whole, and the position of the swing arm 3075 on the pull rod 307 changes synchronously, the swing arm 3075 can drive the limiting block 3062 to slide on the limiting rod 3063, and is limited by the partition plate 3064, in the movement of the limiting block 3062, the push plate 306 and the clamping plate 3061 on the surface approach to each other, at this time the clamping plate 3061 can extrude and fix the reinforcing plate 500.
