Description
Technical Field
[0001] The utility model relates to the technical field of positioning devices, in particular to a positioning device for processing copper capillary tubes. Background Technique
[0002] The copper capillary tube is a throttling component in the refrigeration system, mainly playing the roles of throttling and pressure reduction. In the refrigeration system, when the liquid flowing out of the condenser passes through the thin copper capillary tube, it will encounter a large resistance. Therefore, the flow rate of the liquid refrigerant decreases, restricting the flow rate of the refrigerant entering the evaporator, keeping a relatively stable pressure in the condenser, and the pressure difference at both ends of the copper capillary tube also remains stable. In this way, the pressure of the refrigerant entering the evaporator is reduced, and sufficient evaporation heat absorption is carried out to achieve the purpose of refrigeration. In the processing of copper capillary tubes, a stretching device is required, so it is necessary to effectively position the copper capillary tube and then perform stretching operations. Most of the existing positioning devices position the copper capillary tube by clamping it. For example, the patent with the publication number CN216729193U discloses a positioning device for processing copper capillary tubes, including a support plate. The lower end surface of the support plate is fixedly connected with a base, a perforation is opened inside the support plate, and a clamping mechanism is arranged inside the support plate; the clamping mechanism includes a lead screw, a handle, a moving pressure plate, a clamping pad one, a clamping pad two, a slide bar and a limiting mechanism. The clamping pad one is fixedly connected to the lower end surface of the moving pressure plate, the clamping pad two is fixedly connected to the lower end position inside the perforation, the moving pressure plate is arranged at the top position inside the perforation, the lower part of the lead screw is inserted into the upper end position inside the moving pressure plate, the handle is fixedly connected to the upper end surface of the lead screw, and the number of slide bars is two. The slide bars are fixedly connected to both sides of the upper end surface of the moving pressure plate, which is convenient for the staff to place the copper capillary tube and has a good clamping effect. However, it can only clamp one end of the copper capillary tube. Although the copper capillary tube can be fixed and positioned, it is not convenient for fixed-point positioning and is more troublesome to use.
[0003] Therefore, the utility model provides a positioning device for processing copper capillary tubes. Content of the Utility Model

[0005] To achieve the above object, the utility model is realized through the following technical solutions: A positioning device for processing purple copper capillary tubes, comprising a base, on which a first positioning frame and a second positioning frame are installed.

Specific embodiments
[0020] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0021] Please refer to Figures 1 to 4 , the present utility model provides a technical solution: a positioning device for processing purple copper capillary tubes, including a base 1, a first positioning frame 2 and a second positioning frame 3 are installed on the base 1, a first positioning groove 6 is opened in the first positioning frame 2, a second positioning groove 7 is opened in the second positioning frame 3, a pressure rod 9 is elastically fitted in the first positioning frame 2, a pressing plate 10 is fixed at one end of the pressure rod 9, the pressing plate 10 corresponds to the first positioning groove 6, a screw 15 is in threaded fit in the second positioning frame 3, and a scale plate 14 is installed between the first positioning frame 2 and the second positioning frame 3.
[0022] In this embodiment, a first chute 4 is opened on the base 1, a slider 5 is fixed on the lower side of the second positioning frame 3, the slider 5 corresponds to the first chute 4, a through groove 8 is opened in the first positioning frame 2, the through groove 8 is communicated with the first positioning groove 6, the through groove 8 corresponds to the pressure rod 9, a connecting head 11 is fixed on the pressure rod 9, a plurality of springs 12 are fixed between the connecting head 11 and the first positioning frame 2, second chutes 13 are opened on both the connecting head 11 and the first positioning frame 2, the second chutes 13 correspond to the scale plate 14, the scale plate 14 is of a C-shaped structure, the second positioning frame 3 is in threaded fit with the screw 15, and a pressing head 16 is fixed at one end of the screw 15, and the pressing head 16 is located in the second positioning groove 7.
[0023] Specifically, when clamping and positioning one end of the copper capillary, the screw 15 can be manually rotated to drive the pressure head 16 to move downward, so as to squeeze and fix one end of the copper capillary. Then, the second positioning frame 3 is moved, causing the second positioning frame 3 to slide until it reaches a certain position. At this time, the second positioning frame 3 contacts the scale plate 14, so that the second positioning frame 3 can drive the scale plate 14 to slide until the scale plate 14 separates from the connector 11. At this time, the spring 12 can drive the connector 11 to move downward, thereby driving the pressure rod 9 and the pressing plate 10 to move downward, causing the pressing plate 10 to squeeze the other end of the copper capillary, and thus positioning the copper capillary.
