Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0037] It should be noted that all directional indications in the embodiments of the present application are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture. If the specific posture changes, the directional indication will also change accordingly.

[0038] In this application, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined.

[0039] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0040] At present, the sensor processing welding equipment on the market clamps and fixes the position of the sensor during the processing process to facilitate the staff to perform welding work, but the fixing method is relatively simple, and the welding position cannot be adjusted for angle. In the related technology, by using a clamping mechanism, when fixing the sensor, the screw is rotated to move the thread ring to drive the three groups of first fixed blocks to move, and the sensor is fixed by the contact between the three groups of clamping plates and the sensor. When adjusting the angle, the angle of the entire clamping mechanism and the sensor is adjusted at the same time by turning on the motor, thereby realizing the adjustment of the welding angle, which is convenient for the staff to perform welding work. However, in actual use, its function is relatively simple, and the adjustment steps are relatively complicated. It is also unable to collect and process the odorous smoke generated during welding. It has certain limitations and is inconvenient to use.

[0041] In order to solve the problems in the related technology to a certain extent, the embodiment of the present application provides a welding device for sensor processing. When it is needed, it is only necessary to clamp the sensor with two clamps 23, directly rotate the clamps 23, adjust the angle of the sensor, and operate the adjustment mechanism 30 to fix the position angle of the sensor. This is more convenient and quick, and improves the convenience of the device.

[0042] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0043] Combination Figure 1-Figure 5The embodiment of the present application provides a sensor processing welding device, comprising: a box body 10, a processing table 11 is arranged inside the box body 10, a welding mechanism 12 is installed in the box body 10, a sliding mechanism 20 is arranged in the processing table 11, a mounting plate 21 is slidably connected to the processing table 11, the sliding mechanism 20 is used to adjust the position of the mounting plate 21, one end of the mounting plate 21 is rotatably connected to a mounting rod 22, one end of the mounting rod 22 is fixedly connected to a clamping plate 23, one side of the mounting plate 21 is provided with an adjustment mechanism 30, two fixed plates 31 are slidably connected in the adjustment mechanism 30, and the two fixed plates 31 are slidably connected. Two ends of 31 respectively pass through one side and the bottom of the adjusting mechanism 30, the adjusting mechanism 30 is used to adjust the position of the fixing plate 31, a negative pressure mechanism 40 is provided on one side of the box body 10, a pipe 41 is fixedly connected in the box body 10, the negative pressure mechanism 40 is used to pump the inside of the pipe 41 to negative pressure, a filter plate 42 is slidably connected in the negative pressure mechanism 40, a fixing mechanism 50 is provided inside the box body 10, a connecting plate 51 is fixedly connected to the bottom of the fixing plate 31, a connecting plate 2 52 is slidably connected to the top of the processing table 11, and the fixing mechanism 50 is used to fix the position of the filter plate 42.

[0044] When in use, after the box body 10 is installed in the specified position, any one clamping plate 23 is pulled outward to make the clamping plate 23 slide through the mounting plate 21, and at the same time, the other clamping plate 23 is slid in the opposite direction through the sliding mechanism 20, and then the sensor is placed between the two clamping plates 23, and then the clamping plate 23 is slowly loosened, and the clamping plate 23 is reset through the sliding mechanism 20, while clamping the sensor, and a protrusion is provided on the clamping plate 23 to improve the limiting effect of the sensor, and then the clamping plate 23 is manually rotated to make the clamping plate 23 drive the mounting rod 22 and the sensor to rotate. After adjusting the angle of the sensor, the adjustment mechanism 30 is manually operated to adjust the position of the two fixing plates 31, so that one fixing plate 31 is tightly against the mounting rod 22, and the angle of the mounting rod 22, the clamping plate 23 and the sensor is fixed, and the other fixing plate 31 is tightly against the processing table 11, and the left and right positions of the mounting plate 21, the mounting rod 22 and the clamping plate 23 are fixed (reference direction). Figure 1 ), and then the sensor can be welded by operating the welding mechanism 12. During the welding process, the negative pressure mechanism 40 is turned on to draw the inside of the pipe 41 to a negative pressure state, and then a negative pressure is generated at one end of the pipe 41 close to the sensor, so that the odorous smoke generated during the welding process is sucked into the pipe 41, and then filtered by the filter plate 42 and discharged to the outside, and the filter plate 42 is an activated carbon filter plate;

[0045] Before welding, when the fixing plate 1 31 is not in contact with the mounting rod 22, the fixing mechanism 50 is not inserted into the filter plate 42, so that the filter plate 42 can be easily disassembled. On the contrary, after the position of the fixing plate 1 31 is adjusted by the adjusting mechanism 30, the fixing plate 1 31 pushes the connecting plate 1 51 and the connecting plate 2 52, so that the connecting plate 2 52 fixes the position of the filter plate 42 through the fixing mechanism 50, thereby preventing the position of the filter plate 42 from loosening during the welding process, thereby affecting the filtering effect of the odorous smoke in the pipe 41.

[0046] In some embodiments, one end of the fixing plate 31 is fixedly connected to a pad 32 to increase the contact surface between the fixing plate 31 and the processing table 11 and improve the fixing effect.

[0047] In some embodiments, the sliding mechanism 20 includes: a positioning rod 201 fixedly connected to the inside of the processing table 11; a rack 202 slidably connected to the outside of the positioning rod 201, and the cross-section of the positioning rod 201 is rectangular; a spring 203 is sleeved on the outside of the positioning rod 201, and the two ends of the spring 203 are respectively fixedly connected to the rack 202 and the processing table 11; a gear 204 is rotatably connected to the processing table 11, and the gear 204 is meshed with the two racks 202.

[0048] When sliding, push any one of the clamping plates 23, so that it drives the rack 202 to slide horizontally on the positioning rod 201 through the mounting plate 21. At the same time, through the engagement of the gear 204 with the rack 202, the other rack 202 slides in the processing table 11 and drives the other mounting plate 21 to slide, so that the two mounting plates 21 slide toward each other and stretch the spring 1 203.

[0049] In some embodiments, the adjustment mechanism 30 includes: a mounting seat 301 fixedly connected to one side of the mounting plate 21; a threaded rod 302 rotatably connected to the mounting seat 301; a cross plate 303 fixedly connected to the mounting seat 301; a threaded rod 304 rotatably connected to the cross plate 303, and the two fixed plates 31 are threadedly connected to the threaded rod 1 302 and the threaded rod 2 304 respectively; a bevel gear 305 is fixedly connected to the outer side of the threaded rod 1 302 and one end of the threaded rod 2 304, and the two bevel gears 305 are meshed with each other.

[0050] During adjustment, the threaded rod 1 302 is manually rotated so that it rotates in the mounting seat 301. At the same time, the other threaded rod 2 304 is driven to rotate through the bevel gear 305. Then, the two fixing plates 1 31 are connected with the threaded rods 1 302 and 304 through the threads, so that the two fixing plates 1 31 slide out of the mounting seat 301 at the same time to achieve adjustment.

[0051] In some embodiments, the negative pressure mechanism 40 is composed of an installation box and a vacuum pump. When in use, the vacuum pump is turned on so that the air inlet draws out the air in the pipe 41 and discharges it through the outlet, thereby achieving a negative pressure operation on the pipe 41.

[0052] In some embodiments, the fixing mechanism 50 includes: a fixing seat 501 fixedly connected to the box body 10; a push rod 502 slidably connected to the fixing seat 501; a ring body 503 fixedly connected to the outside of the push rod 502; a spring 2 504 is sleeved on the outside of the push rod 502, and the two ends of the spring 2 504 are respectively fixedly connected to the ring body 503 and the fixing seat 501, one end of the push rod 502 is inserted into the filter plate 42, and the other end is tightly attached to the connecting plate 2 52.

[0053] When in use, the connecting plate 2 52 pushes the push rod 502, causing it to slide in the fixed seat 501, while driving the ring body 503 to slide and pulling the spring 2 504, and then one end of the push rod 502 is inserted into the negative pressure mechanism 40 and into the filter plate 42 to fix the position of the filter plate 42, thereby preventing its position from shifting during welding and improving stability.

[0054] In some embodiments, a groove 60 is opened inside the box body 10, an adjusting rod 61 is slidably connected inside the groove body 60, the processing table 11 is fixedly connected to the adjusting rod 61, and a fixing bolt 62 is threadedly connected to the box body 10, and one end of the fixing bolt 62 is inserted into the adjusting rod 61.

[0055] When in use, manually turn the fixing bolt 62 to make one end of it slide out from the adjusting rod 61, then lift the processing table 11 to drive the adjusting rod 61 to slide out from the groove body 60, so as to realize the disassembly of the processing table 11 and the structure thereon, which is convenient for maintenance and replacement, and vice versa for installation.

[0056] In some embodiments, a slide groove 70 is opened in the box body 10, and a partition 71 is slidably connected in the slide groove 70. A spring three 72 is arranged at the bottom of the partition 71, and the two ends of the spring three 72 are respectively fixedly connected to the partition 71 and the box body 10. A positioning seat 73 is fixedly connected in the box body 10. The pipe 41 is divided into two sections, which are respectively arranged on the back sides of the positioning seat 73, and the two sections of the pipe 41 are connected through the positioning seat 73. One end of the partition 71 is inserted into the positioning seat 73 and is located between the two sections of the pipe 41.

[0057] When the processing table 11 is disassembled, after the adjusting rod 61 slides out of the groove body 60, the partition 71 slides upward in the positioning seat 73 through the rebound force of the spring three 72 until one end of the partition 71 is inserted into the positioning seat 73, so that the two sections of the pipeline 41 are separated by the partition 71, thereby preventing the unfiltered odorous smoke in the negative pressure mechanism 40 from overflowing through the pipeline 41 during disassembly and maintenance.

[0058] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", "some examples", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application.
