Description

Technical Field

[0001] The utility model belongs to the technical field of copper tube welding, in particular to a copper tube welding jig for a chiller. Background Art

[0002] Copper tube, also known as red copper tube, is a pressed and drawn seamless tube. It is light in weight, has good thermal conductivity and high low-temperature strength. It is often used to manufacture heat exchange equipment (such as condensers, etc.) and is also used to assemble low-temperature pipelines in oxygen production equipment. Copper tubes with small diameters are often used to transport pressurized liquids (such as lubrication systems, oil pressure systems, etc.) and as pressure gauges for instruments. They are often used in tap water pipes, heating and refrigeration pipes, and can be used in different environments. Copper tubes combine the advantages of metal and non-metallic pipes, and are the best connecting pipes in hot and cold water systems. Copper tubes are fire-resistant and heat-resistant, and can still maintain their shape and strength at high temperatures without aging. Chillers generally require welding of copper tubes, but the internal space of the chiller is small, so it is inconvenient to weld copper tubes, which affects efficiency. Therefore, an installation jig is made to facilitate personnel to weld copper tubes.

[0003] However, it still has the following disadvantages in actual use:

[0004] 1. The existing copper tube welding jigs of chillers are mostly used to fix the copper tubes by tightening the clamping parts with locking screws. However, this method is cumbersome, time-consuming and labor-intensive during the operation of the staff, resulting in low work efficiency.

[0005] 2. The existing copper tube welding jigs for chillers are mostly used to adjust the height of the clamping parts by tightening screws, which is cumbersome for the staff to operate. When welding copper tubes at various positions, the position of the welding jig needs to be adjusted repeatedly, which is time-consuming and labor-intensive, and has low work efficiency. To this end, we provide a copper tube welding jig for chillers to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Specific embodiment 1

[0033] See also Figures 1 to 4 The utility model is a copper tube welding fixture for a chiller, comprising a magnetic seat 1 and a connecting seat 103 arranged directly above the magnetic seat 1, a fixing screw 105 is fixedly connected to the top center position of the connecting seat 103, an adjusting component 2 is sleeved on the outer wall of the fixing screw 105; the adjusting component 2 comprises a sleeve 201 and an adjusting disk 202 movably connected to the upper surface thereof, and a bracket 203 is installed on the front end face of the sleeve 201.

[0034] Specifically, a fixing nut 101 is fixedly connected to the center position of the upper surface of the magnetic base 1, and the bottom universal ball 102 is threadedly connected to the inside of the fixing nut 101, a connecting groove 1031 is provided at the bottom center position of the connecting seat 103, and the bottom universal ball 102 is located inside the connecting groove 1031, a clamping screw 104 is screwed below the front end surface of the connecting seat 103, and an anti-slip plate 1051 is fixedly connected to the top of the fixing screw 105, a telescopic rod 204 is installed inside the bracket 203, and an adjusting seat 205 is installed at the telescopic end of the telescopic rod 204, an adjusting groove 2051 is provided at the center position of the outer wall of the adjusting seat 205, and a clamping screw 104 is screwed to one side of the front end surface of the adjusting seat 205.

[0035] Furthermore, the entire copper tube welding jig can be fixed to the inner wall of the chiller using the magnetic seat 1, and the bottom universal ball 102 can be installed inside the fixing nut 101 under the action of the thread, wherein the angles of the upper connecting seat 103 and other components can be adjusted under the action of the bottom universal ball 102 and the connecting groove 1031, and can be locked by the clamping screw 104, and the anti-slip plate 1051 can limit the position of the sleeve 201, and the internal thread in the threaded hole wall on the inner wall of the adjusting disk 202 is meshed and connected with the external thread on the outer wall of the fixing screw 105. Therefore, the position of the sleeve 201 can be adjusted when the adjusting disk 202 is rotated with force, and the position of the clamping component can be adjusted under the action of the telescopic rod 204.

[0036] The operation process of this embodiment is as follows: first, the entire copper tube welding jig is adsorbed on the inner wall of the chiller through the magnetic seat 1, and then the angles of the connecting seat 103 and the clamping assembly 3 are adjusted respectively by using the clamping screw 104, and then force is applied to the adjusting disk 202 to make it rotate, and the threaded hole on the inner wall of the adjusting disk 202 is meshed and connected with the external thread on the outer wall of the fixing screw 105. Therefore, when the adjusting disk 202 rotates, it can slide on the outer wall of the fixing screw 105, and the sleeve 201 at the bottom of the adjusting disk 202 slides, and then the adjusting seat 205 is pulled outward, and the adjusting seat 205 is stretched outward under the action of the telescopic rod 204, so that the adjusting seat 205 and the clamping assembly 3 at its end can be adjusted to a suitable position, so as to facilitate the staff to quickly adjust the angle and position of the clamping copper tube, and at the same time, the number of displacements of the copper tube welding jig can be reduced, saving time and high work efficiency. Specific embodiment 2

[0038] See also Figure 1 , 5 On the basis of the specific embodiment 1, what is different from the first embodiment is that: a clamping assembly 3 is provided, the clamping assembly 3 includes a lower clamping plate 301 and an upper clamping plate 303 installed on its upper surface, and a clamping groove 3011 is provided on one side of the opposite end surface of the lower clamping plate 301 and the upper clamping plate 303, which solves the problem that the existing copper tube welding fixture is cumbersome, time-consuming and labor-intensive during the operation of the staff, resulting in low work efficiency.

[0039] Specifically, a top universal ball 302 is installed at the center position of one end surface of the lower clamp plate 301, and the other end of the top universal ball 302 is installed inside the adjustment groove 2051. The front and rear ends of the outer wall of the upper clamp plate 303 are fixedly connected with baffles 3031. The bottom side of the upper clamp plate 303 is fixedly connected with connecting rods 304 at evenly spaced intervals from front to back. The bottom end of the connecting rod 304 passes through the through hole on the upper surface of the lower clamp plate 301 and is connected to the limit plate 306. A spring 305 is sleeved on the outside of the outer wall of the connecting rod 304, and the spring 305 is located between the lower clamp plate 301 and the limit plate 306.

[0040] Furthermore, the top universal ball 302 is located inside the adjustment groove 2051 on the outer wall of the adjustment seat 205. Therefore, the top universal ball 302 can rotate inside the adjustment groove 2051 to achieve the purpose of adjusting the angle of the clamping component. The baffle 3031 can limit the copper tube between the lower clamp plate 301 and the upper clamp plate 303. The upper clamp plate 303 and the limit plate 306 are connected by the connecting rod 304, which plays the role of connecting transmission. Under the action of the elastic performance of the spring 305, the upper clamp plate 303 can be driven to move.

[0041] When the upper clamping plate 303 is moved upward, the upper clamping plate 303 is forced to move upward, and the bottom of the upper clamping plate 303 is connected to the limit plate 306 by the connecting rod 304. Therefore, when the upper clamping plate 303 moves upward, the limit plate 306 will be driven to move under the action of the connecting rod 304, and the spring 305 will be squeezed. At this time, the upper clamping plate 303 and the lower clamping plate 301 can be pulled apart, and then the copper tube is placed in the clamping groove 3011 on the inner side of the lower clamping plate 301 and the upper clamping plate 303, and then the force on the upper clamping plate 303 is stopped. At this time, the limit plate 306 will rebound under the elastic performance of the spring 305, and the upper clamping plate 303 will rebound through the connecting rod 304, and the copper tube can be clamped at the same time, which is convenient for the staff to quickly clamp and fix the copper tube according to the size of the copper tube, saving time, high work efficiency, and a wide range of applications.
