[0031] This example embodiment first provides an adjustment device for a U-shaped slider. (Reference) Figures 1 to 3 As shown, the device includes a clamp 200, a core mold 300, a clamping assembly 400, and a heating furnace. The clamp 200 has a positioning groove 201 extending along a first direction. The positioning groove 201 includes a bottom positioning surface 2101 and a first side positioning surface 2201 and a second side positioning surface 2301 spaced apart and opposite to each other along a second direction. The first side positioning surface 2201 is perpendicular to the bottom positioning surface 2101. The positioning groove 201 is used to accommodate a U-shaped slider 100, and the bottom positioning surface 2101 is used to abut against the outer bottom of the U-shaped slider 100. The first side positioning surface 2201 is used to abut against an outer side wall of the U-shaped slider 100. The core mold 300 is used to place the U-shaped slider 100. The clamping assembly 400 includes an adjusting screw 410 and a position sensor 420. The axis of the adjusting screw 410 is parallel to the second direction, and the adjusting screw 410 is adjustablely inserted into the clamp 200 along the second direction. One end of the adjusting screw 410 extends into the positioning groove 201 via the second side positioning surface 2301 to position and clamp the core mold 300 and the U-shaped slider 100 in the positioning groove 201. The position sensor 420 is disposed on the adjusting screw 410 and is used to monitor the displacement of the adjusting screw 410. The heating furnace is used to heat the clamp 200, the U-shaped slider 100, and the core mold 300, which are clamped together as a whole. Wherein, the first direction is as follows: Figure 2 The direction indicated by the middle arrow ab, the second direction is as follows Figure 1 The direction indicated by the middle arrow cd.

[0032] It needs to be understood that during the adjustment operation of the above device, first, the U-shaped slider 100 needs to be placed in the positioning groove 201 of the clamp 200, and the core mold 300 is placed in the U-shaped slider 100, and it is necessary to ensure that the outer bottom of the U-shaped slider 100 is attached to the bottom positioning surface 2101 of the positioning groove 201, and the outer side wall of one side of the U-shaped slider 100 is attached to the first side positioning surface 2201 of the positioning groove 201; adjust the adjusting screw 410, and use the adjusting screw 410 to position and clamp the core mold 300 and the U-shaped slider 100 in the positioning groove 201, specifically, first move the adjusting screw 410 towards the first side positioning surface 2201, when the core mold 300 and the U-shaped slider 100 have no gap in the second direction, stop moving the adjusting screw 410, then move the adjusting screw 410 away from the first side positioning surface 2201, and cooperate with the position sensor 420 to control the moving distance of the adjusting screw 410 in the second direction, when the preset moving distance is met, stop moving the adjusting screw 410; finally, keep the above adjusted state, and put the clamped clamp 200, U-shaped slider 100 and core mold 300 into the heating furnace for heating and pressure maintaining process.

[0033] It also needs to be understood that the core mold 300 in the embodiment is matched with the standard specification of the U-shaped slider 100, and the standard specification can be reflected in shape and size.

[0034] It also needs to be understood that the above-mentioned preset moving distance can be set to 0-0.05mm, so that the gap between the core mold 300 and the U-shaped slider 100 after adjustment by the clamping assembly 400 in the second direction is within the range of 0-0.05mm, that is, the gap between the core mold 300 and the U-shaped slider 100 is adjusted and restricted, so as to control the deformation amount of the U-shaped slider 100 during the pressure maintaining process in the heating furnace, and realize the adjustment of the perpendicularity of the U-shaped slider 100.

[0035] It also needs to be understood that when the pressure maintaining process is carried out in the heating furnace, the temperature in the heating furnace can be controlled within the range of 150-180℃, and the pressure maintaining time can be set to 3-6 hours.

[0036] By the above adjusting device for the U-shaped slider, on the one hand, the clamp 200, the core mold 300 and the clamping assembly 400 are matched to clamp the U-shaped slider 100 in the positioning groove 201 of the clamp 200, and the verticality of the U-shaped slider 100 is adjusted by the bottom inner wall and the side inner wall vertically arranged on the positioning groove 201; on the other hand, the clamp 200, the U-shaped slider 100 and the core mold 300 clamped into one body are heated by the heating furnace, the U-shaped slider 100 after adjustment can be heat preserved, so that the U-shaped slider 100 clamped is deformed under the action of heat preservation and pressure preservation, and meanwhile, the position sensor 420 and the adjusting screw 410 are matched to control the moving distance of the adjusting screw 410 in the second direction, so as to adjust and constrain the gap between the core mold 300 and the U-shaped slider 100, so as to constrain the deformation of the U-shaped slider 100 under the action of heat preservation and pressure preservation, and then the verticality of the U-shaped slider 100 is adjusted. The device provided in the embodiment can improve the controllability of adjustment and reduce the labor of the operator.

[0037] In the following, reference will be made to Figures 1 to 3 The various parts of the above device in the example embodiment will be described in more detail.

[0038] In one embodiment, as shown in Figure 1 The clamping assembly 400 further comprises a gasket 430, which is clamped between the adjusting screw 410 and the U-shaped slider 100 in the second direction.

[0039] By clamping the gasket 430 between the adjusting screw 410 and the U-shaped slider 100, on the one hand, the force applied by the adjusting screw 410 to the U-shaped slider 100 in the second direction can be uniform, and on the other hand, the outer surface of the U-shaped slider 100 can be prevented from being damaged.

[0040] In one embodiment, the core mold 300 is provided with a pressure sensor, which is detachably installed on the core mold 300. When the core mold 300 is placed in the U-shaped slider 100, the pressure sensor is located between the core mold 300 and the inner wall of the U-shaped slider 100 in the second direction, and is close to the opening of the U-shaped slider 100. The pressure sensor can adopt a strain gauge, which has small volume, high sensitivity and high temperature resistance.

[0041] The pressure sensor is arranged on the core mold 300, and the pressure between the opening part of the U-shaped slider 100 and the core mold 300 can be obtained by using the pressure sensor. When the pressure sensor monitors the pressure, it indicates that the core mold 300 and the U-shaped slider 100 are completely free of gaps in the second direction. At this time, the adjusting screw 410 needs to be stopped from moving towards the first side positioning surface 2201, and then the adjusting screw 410 can be moved away from the first side positioning surface 2201, the pressure sensor arranged on the core mold 300 is removed, and the position sensor 420 is used to control the movement distance of the adjusting screw 410 in the second direction. That is, by arranging the pressure sensor, the time when the adjusting screw 410 stops moving can be more accurately controlled during the movement of the adjusting screw 410 towards the first side positioning surface 2201, so as to ensure that the core mold 300 and the U-shaped slider 100 are free of gaps in the second direction.

[0042] It should be noted that an infrared sensor can also be selected to monitor the gap between the core mold 300 and the U-shaped slider 100 in the second direction, and cooperate with the displacement sensor to ensure that the gap between the core mold 300 and the U-shaped slider 100 in the second direction is kept within the range of 0-0.05 mm before the clamp 200, the U-shaped slider 100 and the core mold 300 clamped together are put into the heating furnace.

[0043] Optionally, the position sensor 420 is a micrometer. During the movement of the adjusting screw 410, the distance of the adjusting screw 410 moving in the second direction can be read by the micrometer, and then the gap between the core mold 300 and the U-shaped slider 100 in the second direction can be obtained.

[0044] For example, the perpendicularity of the first side positioning surface 2201 relative to the bottom positioning surface 2101 is 0-0.07 mm.

[0045] By limiting the perpendicularity of the first side positioning surface 2201 of the positioning groove 201 relative to the bottom positioning surface 2101, the accuracy of adjusting the perpendicularity of the U-shaped slider 100 by using the positioning groove 201 can be ensured.

[0046] In one embodiment, as shown in Figure 2 and Figure 3 The clamp 200 includes a positioning base 210, a first positioning plate 220 and a second positioning plate 230 arranged on the positioning base 210 in the second direction, the positioning base 210, the first positioning plate 220 and the second positioning plate 230 form the positioning groove 201, the upper surface of the positioning base 210 is the bottom positioning surface 2101, the surface of the first positioning plate 220 facing the second positioning plate 230 is the first side positioning surface 2201, and the surface of the second positioning plate 230 facing the first positioning plate 220 is the second side positioning surface 2301.

[0047] The second positioning plate 230 is adjustably arranged along the second direction.

[0048] By adjustably arranging the second positioning plate 230 on the positioning base 210, the clamp 200 is adapted to U-shaped sliders 100 of different specifications.

[0049] Reference Figure 2 and Figure 3 As shown in the first direction, the positioning base 210 is provided with a slide rail 211, and the two ends of the positioning base 210 are provided with locking members 212, and the second positioning plate 230 is slidably connected to the slide rail 211, and when the second positioning plate 230 is adjusted to the working position along the second direction, the locking member 212 is tightly connected with the second positioning plate 230.

[0050] The above-mentioned locking member 212 can be a bolt, and the two ends of the second positioning plate 230 along the first direction can be provided with a threaded connection hole, and when the second positioning plate 230 is adjusted to the working position along the second direction, the locking member 212 can be connected with the threaded connection hole to fix the second positioning plate 230, so that the subsequent clamping assembly 400 can be clamped and worked stably.

[0051] Optionally, a handle 240 is arranged on the outer surface of the clamp 200, so that the operator can put the clamp 200, the U-shaped slider 100 and the core mold 300 into the heating furnace through the handle 240.

[0052] In one embodiment, a threaded hole is formed in the inner wall on the side where the second side positioning surface 2301 of the clamp 200 is located, the adjusting screw 410 is arranged in the threaded hole, and one end of the adjusting screw 410 extends into the positioning groove 201 and abuts against the gasket 430 along the second direction, and the other end is located outside the U-shaped slider 100. The adjusting screw 410 is adjustably arranged in the clamp through the threaded hole, which not only has low cost, but also facilitates the precision control of the displacement of the adjusting screw 410 in the second direction.

[0053] Optionally, the other end of the adjusting screw 410 along the second direction is provided with a holding part 411. By arranging the holding part 411 on the adjusting screw 410, the operator can be convenient to rotate.

[0054] For example, along the first direction, the length of the clamp 200 and the length of the core mold 300 are N times the length of the U-shaped slider 100. In this way, multiple U-shaped sliders 100 can be adjusted at one time.
