Description

Technical Field

[0001] This utility model belongs to the field of evaporator fin processing technology, specifically referring to an evaporator fin tube-insertion positioning device. Background Technology

[0002] Evaporator fins are a common heat exchange device widely used in refrigeration, air conditioning, chemical and other fields. By setting multiple sets of fins, the contact area between the pipes passing through the fins and the air is increased, thereby achieving the purpose of heat dissipation.

[0003] Existing evaporator fin tube-passing positioning devices, such as the evaporator fin tube-passing positioning device disclosed in application number CN202220901474.3, can automatically transport evaporator fins toward copper tubes and achieve tube-passing through rollers arranged in a linear array along the horizontal direction.

[0004] In actual processing, since the fins are mostly parallel plate structures, the thickness and spacing of the fin plates used in different evaporators are different. It is difficult to effectively fix each group of fin plates by relying solely on plates and rollers. During the tube insertion process, the fin plates are prone to displacement and deflection, which affects the processing accuracy. Utility Model Content

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides an evaporator fin tube-insertion positioning device, which effectively solves the problem that the existing evaporator fin tube-insertion positioning devices cannot fix each group of fin plates and improve stability and accuracy.

[0006] The technical solution adopted by this utility model is as follows: The evaporator fin tube positioning device proposed by this utility model includes a base, a sliding groove is provided on one side of the upper end of the base, and guide rails are symmetrically distributed on one side of the sliding groove. The guide rails are perpendicular to the sliding groove and fixed to the bottom of the base. Symmetrical lifting guide components are connected to the sliding groove, and an adjustable distance mechanism is connected between the two lifting guide components. The lifting guide component includes a guide rail slidably connected to the sliding groove, a guide slider slidably connected to the guide rail, and a fixed shaft is fixed on the guide slider near the guide rail. A scissor bar is rotatably connected to the fixed shaft, and a fin clamping mechanism is provided at the end of the fixed shaft away from the guide rail.

[0007] As an improvement to the proposed solution, the fin clamping mechanism consists of a lower support plate, an upper pressure plate, and an insert block. The lower support plate is fixed on a fixed shaft, the upper pressure plate is located above the lower support plate, the insert block is fixed to the lower end of the upper pressure plate, and the upper pressure plate is inserted into the upper end of the lower support plate through the insert block. A tension spring is connected between the bottom of the lower support plate and the insert block.

[0008] As an improvement to the solution, the adjusting mechanism includes a support block slidably connected in the middle of the slide groove, and an adjusting plate is vertically fixed to the upper end of the support block.

[0009] As an improvement to the solution, the adjusting plate is provided with several guide grooves, and the point spacing on each group of guide grooves is the same in the same vertical plane. A drive shaft is slidably connected in the guide groove, one end of the drive shaft is connected to the hinge shaft of the scissor bar, and a screw is rotatably connected in the sliding groove. At the same time, the support block is threadedly connected to the screw.

[0010] As an improvement to the solution, a hydraulic cylinder is provided on the inner wall of the guide rail, and a pressing slider is fixed at the output end of the hydraulic cylinder. The pressing slider is slidably connected to the guide rail. At the same time, a fixing plate is fixed at the upper end of the pressing slider, and a clamping plate is fixed to the side of the fixing plate near the guide rail by bolts.

[0011] The beneficial effects of this utility model by adopting the above structure are as follows:

[0012] 1. Equipped with multiple fin clamping mechanisms, the upper pressure plate and lower support plate are kept close together by tension springs, which can clamp each group of fin plates individually, ensuring the parallelism and positional accuracy between each group of fin plates, and can adapt to the clamping and fixing of fin plates of different thicknesses. It is flexible to use and easy to operate.

[0013] 2. The spacing between each set of scissor bars can be changed through the spacing adjustment mechanism. As the spacing between the scissor bars changes, the angles on both sides of the scissor bars also change, thereby changing the fixed spacing of the fin plate to meet the needs of different fixed spacings and making the use more flexible.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the present invention proposes an evaporator fin tube-mounting device, comprising a base 1, a slide groove 2 on one side of the upper end of the base 1, and guide rails 3 symmetrically distributed on one side of the slide groove 2. The guide rails 3 are perpendicular to the slide groove 2 and fixed to the bottom of the base 1. Symmetrical lifting guide components 4 are connected to the slide groove 2, and an adjustable distance mechanism 5 is connected between the two lifting guide components 4. The lifting guide component 4 includes a guide slide rail 6 slidably connected to the slide groove 2, a guide slider 7 slidably connected to the guide slide rail 6, and a fixed shaft 8 fixed on the guide slider 7 near the guide rail 3. A scissor bar 9 is rotatably connected to the fixed shaft 8, and a fin clamping mechanism 10 is provided at the end of the fixed shaft 8 away from the guide slide rail 6.

[0023] The opening and closing angle of the scissor bar 9 is changed by adjusting the spacing of the scissor bar 9, thereby allowing the fin clamping mechanisms 10 at both ends to be adjusted at equal intervals to meet the clamping requirements of fin plates with different spacing.

[0024] like Figure 2 and Figure 5As shown, the fin clamping mechanism 10 consists of a lower support plate 11, an upper pressure plate 12, and an insert block 13. The lower support plate 11 is fixed on the fixed shaft 8, the upper pressure plate 12 is located above the lower support plate 11, and the insert block 13 is fixed to the lower end of the upper pressure plate 12. The upper pressure plate 12 is inserted into the upper end of the lower support plate 11 through the insert block 13. A tension spring 14 is connected between the bottom of the lower support plate 11 and the insert block 13.

[0025] like Figure 3 As shown, the adjusting mechanism 5 includes a support block 15 slidably connected to the middle of the slide groove 2, and an adjusting plate 16 is vertically fixed to the upper end of the support block 15.

[0026] like Figure 1 As shown, the adjustable plate 16 is provided with several guide grooves 17, and the point spacing on each group of guide grooves 17 is the same in the same vertical plane. A drive shaft 18 is slidably connected in the guide groove 17. One end of the drive shaft 18 is connected to the hinge shaft of the scissor bar 9. A screw 19 is rotatably connected in the slide groove 2. At the same time, the support block 15 is threadedly connected to the screw 19.

[0027] like Figure 1 and Figure 3 As shown, a hydraulic cylinder 20 is provided on the inner wall of the guide rail 3, and a pressing slider 21 is fixed at the output end of the hydraulic cylinder 20. The pressing slider 21 is slidably connected to the guide rail 3. At the same time, a fixing plate 23 is fixed at the upper end of the pressing slider 21, and a clamping plate 22 is fixed to the side of the fixing plate 23 near the guide rail 6 by bolts.

[0028] In practical use, rotating the screw 19 causes the support block 15 to slide along the slide groove 2, which in turn drives the adjusting plate 16 on it to move laterally. As the adjusting plate 16 moves, the guide groove 17 on it drives the drive shaft 18 to adjust the spacing, thereby changing the bifurcation angle of the scissor bar 9 on the drive shaft 18, so that the spacing of each group of fin clamping mechanisms 10 is adjusted at equal intervals, which can meet the needs of fixing different fin plates. As the fin plate is inserted from one side of the lower support plate 11 and the upper pressure plate 12, the upper pressure plate 12 and the lower support plate 11 are separated. Under the action of the tension spring 14, the upper pressure plate 12 always presses the fin plate and the lower support plate 11 tightly. Then, the hydraulic cylinder 20 is opened to push the pressing slider 21 to move along the guide rail 3, which drives the abutment plate 22 on it to press one side of the fin plate down to the lower support plate 11 and the upper pressure plate 12 to complete the fixing. Then, the pipe can be inserted into the interface on the fin plate from above. The above is the entire process of using the evaporator fin tube positioning device.

[0029] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
