Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. It is understood that, without conflict, some technical means of the various embodiments described herein can be substituted for or combined with each other.

[0031] In the description of this utility model, the terms "first," "second," etc., are used only to distinguish the described objects and have no sequential or technical meaning. Therefore, objects specified with "first," "second," etc., may explicitly or implicitly include one or more of those objects. Furthermore, the words "one" or "a" do not indicate a quantity limitation, but rather indicate the presence of at least one, while "multiple" indicates at least two.

[0032] In the description of this utility model, references to "one embodiment" or "some embodiments" mean that one or more embodiments of the utility model include the specific features, structures, or characteristics described in connection with that embodiment. Therefore, the phrases "one embodiment," "some embodiments," "other embodiments," "and other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized.

[0033] This utility model provides a welding device for quartz side plate positioning blocks, which can ensure the positioning and welding accuracy of quartz side plates and positioning blocks and improve production efficiency.

[0034] Reference Figure 1 and Figure 2 In some embodiments, the welding equipment 100 for the quartz side plate positioning block includes a base 10, a first clamping mechanism 20 disposed on the base 10 for fixing the quartz side plate 200, a second clamping mechanism 30 disposed on the base 10 for fixing the positioning block 300, and two sets of welding mechanisms 40 disposed on the base 10 and respectively located on both sides of the second clamping mechanism 30. It should be understood that the following first direction A may correspond to... Figure 1 The welding equipment 100 is in the left and right directions, and the second direction B corresponds to Figure 1 The welding equipment 100 is in the front-back direction, and the third direction C is sandwiched between the first direction A and the second direction B. The third direction C has a non-right angle with both the first direction A and the second direction B.

[0035] Specifically, in conjunction with reference Figures 1 to 3 The first clamping mechanism 20 includes a support frame 21, a rotary clamping cylinder 22 disposed on one side of the support frame 21, and multiple sets of limiting components 23 disposed on multiple sides of the support frame 21. The limiting components 23 include a first slide 231 and a limiting block 232. The first slide 231 is disposed along a first direction A or a second direction B, and the limiting block 232 is movably disposed on the corresponding first slide 231.

[0036] The number of limit components 23 can be reasonably set according to the actual situation, referring to... Figure 1 In some embodiments, there are three sets of limiting components 23, which are respectively disposed on the three sides of the support frame 21. When the quartz side plate 200 is placed on the support frame 21, the limiting blocks 232 in the three sets of limiting components 23 advance toward the corresponding side of the quartz side plate 200, thereby effectively positioning the quartz side plate 200 in three directions. The rotary clamping cylinder 22 can press down above the quartz side plate to further ensure the positioning accuracy and stability of the quartz side plate. The rotary clamping cylinder 22 can be a rotary clamping cylinder product in the prior art, such as the QCKL series rotary clamping cylinder produced by Airtac. The first slide block 231 can be a linear guide module, ball screw module, etc. in the prior art. Its structure and working principle are prior art and will not be described in detail here.

[0037] Reference Figure 1 and Figure 4The second clamping mechanism 30 includes a second slide 31, a base plate 32, a third slide 33, a mounting plate 34, and a clamping assembly 35. The second slide 31 is disposed along a second direction B (in other embodiments, the second slide 31 may also be disposed along a first direction A), and the base plate 32 is movably disposed on the second slide 31. The third slide 33 is disposed on the base plate 32 along a third direction C. The mounting plate 34 is movably disposed on the third slide 33, and the clamping assembly 35 is disposed on the mounting plate 34, with the clamping assembly 35 facing the support frame 21.

[0038] The clamping assembly 35 is used to clamp the positioning block 300. The second slide 31 and the third slide 33 cooperate to push the clamping assembly 35 and the positioning block 300 toward the quartz side plate 200 on the support frame 21, thereby achieving precise alignment between the positioning block 300 and the quartz side plate 200. The second slide 31 and the third slide 33 can be products such as linear guide modules and ball screw modules in the prior art. Their structure and working principle are existing technologies and will not be described in detail here.

[0039] Reference Figure 1 and Figure 8 Each welding mechanism 40 includes a fourth slide 41, a welding torch support 42, and a welding torch 43. The fourth slides 41 in the two welding mechanisms 40 are respectively arranged along the first direction A and the second direction B. The welding torch support 42 is movably arranged on the corresponding fourth slide 41, and the welding torch 43 is arranged on the welding torch support 42.

[0040] When the positioning block 300 is precisely aligned with the quartz side plate 200, the fourth slide 41 can drive the corresponding welding torch bracket 42 and welding torch 43 to advance towards the positioning block 300, so that the nozzle of the welding torch 43 is aligned with the connection between the quartz side plate 200 and the positioning block 300, and the high-temperature flame emitted by the welding torch 43 welds the quartz side plate 200 and the positioning block 300 together. The fourth slide 41 can be a linear guide module, ball screw module, or other products in the prior art, and the welding torch 43 can be an oxyhydrogen welding torch in the prior art. The structure and working principle of these products are all prior art and will not be described in detail here.

[0041] The working process of the welding equipment 100 is as follows: the quartz side plate 200 is placed on the support frame 21, and the limiting block 232 of the three sets of limiting components 23 is pushed towards the corresponding side of the quartz side plate 200, thereby effectively positioning the quartz side plate 200 in three directions; the rotary clamping cylinder 22 presses down above the quartz side plate to further ensure the positioning accuracy and stability of the quartz side plate. The clamping component 35 clamps the positioning block 300, and the second slide 31 and the third slide 33 cooperate to push the clamping component 35 and the positioning block 300 towards the quartz side plate 200 on the support frame 21, so that the positioning block 300 is precisely aligned with the quartz side plate 200. Then, the fourth slide 41 drives the corresponding welding torch bracket 42 and welding torch 43 to move towards the positioning block 300, so that the nozzle of the welding torch 43 is aligned with the connection between the quartz side plate 200 and the positioning block 300, and the high temperature flame emitted by the welding torch 43 is used to weld the quartz side plate 200 and the positioning block 300 together.

[0042] The aforementioned welding equipment 100 has a compact structure and high integration. It can stably clamp the quartz side plate 200 and the positioning block 300, and achieve precise alignment between the positioning block 300 and the quartz side plate 200. The two sets of welding mechanisms 40 can simultaneously weld the contact parts between the positioning block 300 and the quartz side plate 200, thereby ensuring product accuracy and improving production efficiency.

[0043] Reference Figures 4 to 7 In some preferred embodiments, the clamping assembly 35 includes a clamp seat 351, a clamping block 352, a cylinder bracket 353, a clamping cylinder 354, a connecting rod shaft 355, a connecting rod 356, and a clamp 357. The clamping block 352 and the cylinder bracket 353 are respectively disposed on both sides of the clamp seat 351 along the third direction C. The clamping block 352 is provided with a clamping groove 3521 for placing the positioning block 300. The clamping cylinder 354 is disposed on the cylinder bracket 353 along the third direction C. The clamp seat 351 is provided with a shaft hole 3511 along the third direction C, and the connecting rod shaft 355 is movably inserted into the shaft hole 3511. The first end of the connecting rod shaft 355 is connected to the piston rod of the clamping cylinder 354, and the second end of the connecting rod shaft 355 is hinged to the first end of the connecting rod 356. The clamp 357 is L-shaped and has a clamping part 3571, a connecting part 3572, and a corner part 3573 provided between the clamping part 3571 and the connecting part 3572. The clamping part 3571 is above the clamping groove 3521. The connecting part 3572 is hinged to the clamp seat 351, and the corner part 3573 is hinged to the second end of the connecting rod 356.

[0044] Reference Figure 5In application, the positioning block 300 is placed in the clamping groove 3521. The piston rod of the clamp cylinder 354 extends, driving the connecting rod shaft 355 to move to the left. Through the hinged joint structure between the connecting rod shaft 355 and the connecting rod 356, the hinged joint structure between the connecting part 3572 and the clamp seat 351, and the hinged joint structure between the corner part 3573 and the connecting rod 356, the clamp 357 is driven to rotate counterclockwise around the hinge axis between the connecting part 3572 and the clamp seat 351, thus driving the clamp 357 to press down and press the positioning block 300 into the clamping groove 3521, ensuring the clamping stability of the positioning block 300. After welding is completed, the piston rod of the clamp cylinder 354 retracts and, through the aforementioned hinged joint structures, drives the clamp 357 to rotate clockwise around the hinge axis between the connecting part 3572 and the clamp seat 351, thus driving the clamp 357 to lift up and release the positioning block 300.

[0045] Reference Figure 7 In some preferred embodiments, a first pressing block 3574 is provided below the pressing part 3571. When the clamp 357 presses down, the first pressing block 3574 can cover the clamping groove 3521, thereby ensuring the clamping stability of the positioning block 300.

[0046] Furthermore, the first pressure block 3574 can be made of graphite, which can effectively prevent damage to the surface of the brittle quartz positioning block.

[0047] Reference Figure 6 The clamp base 351 is provided with a limiting groove 3512, and the connecting part 3572 is located in the limiting groove 3512, and the connecting part 3572 is hinged to the two side walls of the limiting groove 3512. The limiting groove 3512 can accurately constrain the rotation range of the clamp, improving the reliability of equipment operation and repeatability.

[0048] Reference Figure 5 The piston rod of the clamp cylinder 354 is connected to the first end of the connecting rod shaft 355 through the floating joint 358, which can eliminate the influence caused by coaxiality error, reduce assembly difficulty, and improve system reliability, durability and tolerance.

[0049] Combined with reference Figure 1 and Figure 4 The base 10 is provided with blocking blocks 36 at both ends corresponding to the second slide 31. The blocking blocks 36 at both ends can limit the movement range of the base plate 32 and ensure the reliability of the equipment.

[0050] Reference Figure 3 In some preferred embodiments, the support frame 21 is provided with a support bar 211. The pressure arm of the rotary pressing cylinder 22 is provided with a second pressure block 221. Furthermore, the support bar 211 and the second pressure block 221 can be made of graphite material, which can effectively avoid damaging the surface of the brittle quartz side plate.

[0051] The welding equipment for the quartz side plate positioning block of this utility model has a compact structure and high integration. It uses multiple sets of limiting components and rotary clamping cylinders in the first clamping mechanism to accurately position and reliably clamp the quartz side plate. The second clamping mechanism stably clamps the positioning block and achieves precise alignment between the positioning block and the quartz side plate. The two welding mechanisms can simultaneously weld the contact parts between the positioning block and the quartz side plate, thereby ensuring product accuracy and improving production efficiency.

[0052] This utility model has been described by the above-described embodiments; however, these embodiments are merely examples for implementing this utility model. It must be noted that the disclosed embodiments do not limit the scope of this utility model. Conversely, any modifications and refinements made without departing from the spirit and scope of this utility model are within the scope of patent protection of this utility model.
