Technical Field

[0001] This utility model relates to the field of guide wheel spindle fixing technology, specifically to a guide wheel spindle mounting device. Background Technology

[0002] In the field of monocrystalline silicon manufacturing, the three-point winding system is mainly used for seed crystal lifting mechanisms and auxiliary winding systems, which are used to achieve high-precision, pollution-free, and stable wire rope winding and unwinding control.

[0003] In a three-point winding drum system, the traditional guide wheel spindle requires not only bolts for locking during installation, but also auxiliary workpieces at both ends of the spindle for positioning and fixation. This can involve mounting the spindle to a bearing housing, or using end plates or flanges to secure it, presenting installation difficulties. Furthermore, when the three guide wheel spindles rotate around their midpoint and wind steel wire for extended periods, the wire may wear down the grooves on the coated end face of the spindle, affecting subsequent wire winding. This can lead to the need for time-consuming replacement of the guide wheel spindles.

[0004] Therefore, it is necessary to invent a guide wheel spindle mounting device to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a guide wheel spindle mounting device, which solves the problem that when the groove on the end face of the guide wheel spindle is worn during actual use, it takes a lot of time to replace the guide wheel spindle.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A guide wheel spindle mounting device includes a spindle body with connecting shafts at both ends. Multiple positioning holes are formed on both end faces of the spindle body. Mounting assemblies are connected to both ends of the spindle body. Three spindle bodies are arranged equidistantly around the axis of the mounting assemblies. Each mounting assembly has multiple through slots for mounting the spindle bodies. Each mounting assembly includes a central mounting plate, and an auxiliary locking assembly is provided inside the central mounting plate. The auxiliary locking assembly includes a limiting pin that can be inserted into the positioning holes.

[0008] As a preferred embodiment of this utility model, waist-shaped guide rings are fixedly installed on the outer sides of the connecting shafts at both ends of the main shaft body, and a guide ring slot is provided in the middle mounting plate. The guide ring slot includes a rectangular segment and an arc segment. The rectangular segment fits with the parallel end faces on both sides of the waist-shaped guide ring, and the arc segment fits with the curved surface of the waist-shaped guide ring. The auxiliary locking components are located on both sides of the arc segment.

[0009] As a preferred embodiment of this utility model, the auxiliary locking assembly includes an adjusting slider, a return spring, and an ejector component. The two adjusting sliders are slidably disposed on the inner side of the central mounting plate. The end face of the adjusting slider is provided with a curved surface that can fit with the arc segment of the waist-shaped guide ring. The other end of the adjusting slider is provided with a receiving groove, and the return spring is installed inside the receiving groove.

[0010] As a preferred embodiment of this utility model, the ejector component includes an ejector spring, the middle of the adjusting slider is provided with an inclined pressing groove, the mounting assembly also includes an inner mounting plate, the inner side of the inner mounting plate is provided with a through groove for the sliding of the limiting pin, the ejector spring is sleeved on the outer side of the limiting pin, and the top of the limiting pin is provided with a pressing inclined surface that can fit with the pressing groove.

[0011] As a preferred embodiment of this utility model, the position of the limiting pin is adapted to the positioning hole; when the pressing groove squeezes the limiting pin, the limiting pin extends to the inner side of the positioning hole.

[0012] As a preferred embodiment of this utility model, the waist-shaped guide ring is provided with multiple limiting holes, and the mounting assembly is provided with locking bolts for fixing the waist-shaped guide ring; when the waist-shaped guide ring is inserted into the guide ring slot and rotated 90 degrees, the position of the limiting holes corresponds to the locking bolts.

[0013] As a preferred embodiment of this utility model, the mounting assembly further includes an outer mounting plate, which is fixedly connected to the middle mounting plate. The outer mounting plate has multiple threaded holes, and the locking bolts fix the waist-shaped guide ring through the threaded holes.

[0014] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0015] In this invention, an auxiliary locking device is provided inside the mounting assembly. By rotating the waist-shaped guide ring, the spindle can be limited to prevent displacement. After the spindle body rotates, the waist-shaped guide ring presses the adjusting slider, causing the adjusting slider to move to both sides. At the same time, it presses the push groove to squeeze the limiting pin, causing the limiting pin to extend into the positioning holes at both ends of the spindle body, further limiting the spindle body and improving the installation firmness. When it is necessary to disassemble the spindle, the locking bolts can be removed and the spindle body rotated 90 degrees to quickly disassemble the spindle body. After the spindle body is disassembled, the return spring can drive the adjusting slider to return to its original position, causing the limiting pin to move away from the positioning hole, reducing the difficulty of disassembling the spindle.

[0023] The present invention will be further described below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and should not be used to limit the scope of protection of the present invention.

[0024] This utility model provides, for example Figure 1-4 The illustrated guide wheel spindle mounting device includes a spindle body 1, with connecting shafts 101 at both ends. Multiple positioning holes 102 are formed on both end faces of the spindle body 1. Mounting assemblies 2 are connected to both ends of the spindle body 1. Three spindle bodies 1 are arranged equidistantly around the axis of the mounting assemblies 2. Each mounting assembly 2 has multiple through slots for mounting the spindle bodies 1. The mounting assembly 2 includes a central mounting plate 203, inside which is an auxiliary locking assembly 3. The auxiliary locking assembly 3 includes limiting pins 307 that can be inserted into the positioning holes 102. A rotating shaft is located at the center of the mounting assembly 2. Rotation of the rotating shaft drives the three spindle bodies 1 to rotate around their axis, thus controlling the winding and unwinding of the steel wire.

[0025] Waist-shaped guide rings 103 are fixedly installed on the outer sides of the connecting shafts 101 at both ends of the spindle body 1. A guide ring slot 201 is provided in the middle mounting plate 203. The guide ring slot 201 includes a rectangular segment and an arc-shaped segment. The rectangular segment fits against the parallel end faces on both sides of the waist-shaped guide ring 103, and the arc-shaped segment fits against the curved surface of the waist-shaped guide ring 103. The auxiliary locking assembly 3 is located on both sides of the arc-shaped segment. The waist-shaped guide ring 103 can constrain the position of the spindle body 1 and guide it using the guide ring slot 201, facilitating the limiting of the spindle body 1's position.

[0026] The auxiliary locking assembly 3 includes an adjusting slider 301, a return spring 303, and an ejector component. The two adjusting sliders 301 are slidably disposed inside the central mounting plate 203. The end face of each adjusting slider 301 has a curved surface that can conform to the arcuate segment of the waist-shaped guide ring 103. The other end of each adjusting slider 301 has a receiving groove 302, and the return spring 303 is installed inside the receiving groove 302. When the adjusting slider 301 moves to its limit position, the end face of the adjusting slider 301 conforms to the inner wall of the central mounting plate 203, and the curved surface of the adjusting slider 301 conforms to the curved surface of the waist-shaped guide ring 103, ensuring a limiting effect on the waist-shaped guide ring 103 and preventing it from falling off due to external force.

[0027] The ejector component includes an ejector spring 305. The adjusting slider 301 has an inclined pressing groove 304 in its center. The mounting assembly 2 also includes an inner mounting plate 202. The inner side of the inner mounting plate 202 has a through groove for sliding the limiting pin 307. The ejector spring 305 is sleeved on the outer side of the limiting pin 307. The top of the limiting pin 307 has a pressing inclined surface 306 that can engage with the pressing groove 304. A retaining ring is sleeved on the outer side of the limiting pin 307 to intercept the ejector spring 305. Both ends of the retaining ring have guiding protrusions. The retaining ring and protrusions ensure that the pressing inclined surface 306 of the limiting pin 307 can directly engage with the inclined surface of the pressing groove 304.

[0028] The position of the limiting pin 307 is adapted to the positioning hole 102; when the pressing groove 304 squeezes the limiting pin 307, the limiting pin 307 extends to the inner side of the positioning hole 102. When the pressing groove 304 separates from the limiting pin 307, the ejector spring 305 drives the limiting pin 307 away from the positioning hole 102, which facilitates the disassembly of the spindle body 1.

[0029] The waist-shaped guide ring 103 has multiple limiting holes 104, and the mounting assembly 2 is provided with locking bolts 205 for fixing the waist-shaped guide ring 103. When the waist-shaped guide ring 103 is inserted into the guide ring slot 201 and rotated 90 degrees, the position of the limiting holes 104 corresponds to the locking bolts 205. After the waist-shaped guide ring 103 rotates 90 degrees, the curved surface of the waist-shaped guide ring 103 fits against the curved surface of the adjusting slider 301, and the limiting holes 104 and the locking bolts 205 are connected by threads to fix the spindle body 1, ensuring a secure fixation effect.

[0030] The mounting assembly 2 also includes an outer mounting plate 204, which is fixedly connected to the middle mounting plate 203. The outer mounting plate 204 has multiple threaded holes, and the locking bolt 205 fixes the waist-shaped guide ring 103 through the threaded holes. The outer mounting plate 204, the middle mounting plate 203, and the inner mounting plate 202 are sequentially fixedly connected, and the threaded holes simultaneously penetrate multiple mounting plates. When the locking bolt 205 is installed into the threaded hole, the locking bolt 205 passes through the outer mounting plate 204, the waist-shaped guide ring 103, and the inner mounting plate 202 in sequence, improving the reliability of the connection.

[0031] This invention features an auxiliary locking device inside the mounting assembly 2. By rotating the waist-shaped guide ring 103, the spindle can be limited to prevent displacement. After the spindle body 1 rotates, the waist-shaped guide ring 103 presses against the adjusting slider 301, causing it to move to both sides. Simultaneously, it presses against the push groove 304, squeezing the limiting pin 307. This causes the limiting pin 307 to extend into the positioning holes 102 at both ends of the spindle body 1, further limiting the spindle body 1 and improving installation stability. When the spindle needs to be disassembled, the locking bolt 205 can be removed, and the spindle body 1 can be rotated 90 degrees for quick disassembly. After disassembly, the return spring 303 can drive the adjusting slider 301 to return to its original position, moving the limiting pin 307 away from the positioning holes 102, reducing the difficulty of spindle disassembly.

[0032] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
