[0022] In order to make the technical solution of the present invention clearer, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Example 1

[0024] like Figure 1-2This embodiment provides a welding positioning fixture for a quartz boat, including: a base plate 1, on which a receiving groove 15 is provided; a first limiting block 21 and a second limiting block 22 respectively connected to both sides of the base plate 1, the first limiting block 21 being provided with a first groove 211, and the second limiting block 22 being provided with a second groove 221; a stopper 3 and a back plate 4 respectively connected to both ends of the base plate 1.

[0025] Specifically, the bottom plate 1 is used to carry the accommodating groove 15, and the accommodating groove 15 is used to accommodate the middle plate 63 of the quartz boat 6, so as to limit the middle plate 63 of the quartz boat 6 along the X direction; the first limiting block 21 is used to carry the first groove 211, and the first groove 211 is used to accommodate the first side plate 61 of the quartz boat 6, so as to limit the first side plate 61 of the quartz boat 6 along the X direction; the second limiting block 22 is used to carry the second groove 221, and the second groove 221 is used to accommodate the second side plate 61 of the quartz boat 6. The side plate 62 is convenient for limiting the second side plate 62 of the quartz boat 6 in the X direction; the stopper 3 is used to conflict with the V-shaped plate 64 of the quartz boat 6, and cooperate with the first side plate 61 of the quartz boat 6 and the second side plate 62 of the quartz boat 6 to limit the V-shaped plate 64 of the quartz boat 6 in the Y direction. The V-shaped plate 64 of the quartz boat 6 is also used to conflict with the bottom plate 1, so that the bottom plate 1 limits the V-shaped plate 64 of the quartz boat 6 in the Z direction; the back plate 4 is used to conflict with the main plate 65 of the quartz boat 6, and The first side plate 61 of the quartz boat 6 and the second side plate 62 of the quartz boat 6 are used to limit the main plate 65 of the quartz boat 6 along the Y direction. The main plate 65 of the quartz boat 6 is also used to conflict with the bottom plate 1, so that the bottom plate 1 can limit the main plate 65 of the quartz boat 6 along the Z direction. In summary, the welding positioning fixture of the quartz boat 6 of the present application is convenient for positioning the middle plate 63, the first side plate 65 and the back plate 4 of the quartz boat 6 through the bottom plate 1, the first limiting block 21, the second limiting block 22, the stopper 3 and the back plate 4. 1 and the second side plate 62 and other components produce good positioning performance, which is convenient for ensuring that the welding effect of the quartz boat 6 is good. It should be noted that when working, the middle plate 63, the first side plate 61 and the second side plate 62 and other components of the quartz boat 6 can be assisted in positioning and locally spot-welded by the welding positioning fixture of the quartz boat 6 of the present application, and then the three-coordinate measurement is used to determine whether the size of the quartz boat 6 is qualified. If qualified, the quartz boat 6 is completely welded to ensure that the welding effect of the quartz boat 6 is good.
