Description

Technical Field

[0001] This utility model belongs to the technical field of fabric positioning fixtures, and particularly relates to a rotary fabric quick positioning fixture. Background Technology

[0002] In the speaker manufacturing industry, the fabric covering process is one of the key steps affecting product appearance quality and production efficiency. The accuracy of the fabric covering positioning and the ease of operation directly affect the smooth progress of subsequent assembly and the overall quality of the product.

[0003] Currently, the common method for positioning speaker enclosure fabric in the industry involves cutting grooves on the side of a cylinder and embedding eight pins within these grooves, along with a spring mechanism. In practice, after completing the fabric application, workers must manually pry out each pin one by one to attach the fabric for subsequent processes. However, this method is not only time-consuming and labor-intensive, but each pin will also be slightly misaligned, easily causing the fabric to come loose and increasing the defect rate.

[0004] Therefore, the inventors dedicated themselves to designing a fabric positioning fixture to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a rotary fabric covering quick positioning fixture, which not only saves time and effort and provides accurate positioning, but also improves the efficiency and quality of the speaker shell fabric covering process.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A rotary fabric applicator quick positioning fixture includes a base, a rotating block rotatably connected within the rotational space of the base, a knob fixed on the rotating block, the knob passing through the base and extending out of the base, and multiple sliders connected to the lower limit of the rotating block. All the sliders are distributed circumferentially around the base, and a pin is fixedly connected to the outer side of each slider along the radial direction of the base. Each slider is slidably connected to the base along the radial direction of the base to achieve switching between two states: the corresponding pin is extended out of the base and retracted into the base.

[0007] As an improvement of the rotary fabric quick positioning fixture of this utility model, the bottom of the rotating space is provided with multiple sliding grooves, and all the sliders are slidably arranged in all the sliding grooves in a corresponding manner.

[0008] As an improvement of the rotary fabric quick positioning fixture of this utility model, the outer wall of the base is provided with through holes for the corresponding ejector pins to pass through at positions opposite to all the slide grooves.

[0009] As an improvement of the rotary fabric quick positioning fixture of this utility model, multiple elongated arc-shaped sliding limit holes on the end face of the rotating block are inclined and spaced apart along the circumference of the rotating block, and the sliding column limit on the slider passes through the corresponding sliding limit holes.

[0010] As an improvement of the rotary fabric quick positioning fixture of this utility model, each of the slide grooves has an elongated sliding limiting groove at the bottom along the radial direction of the base, and each slide column passes through the corresponding slider and its lower end extends out of the slider and is limited to the corresponding sliding limiting groove.

[0011] As an improvement of the rotary fabric quick positioning fixture of this utility model, a locking notch is provided on the side wall of the sliding column, and a locking adjustment screw is threadedly connected to the side of the slider away from the corresponding ejector pin. The locking end of the locking adjustment screw is limited and engaged with the locking notch.

[0012] As an improvement of the rotary fabric quick positioning fixture of this utility model, multiple rotary limiting posts are vertically fixed in the rotary space, and multiple long arc-shaped rotary limiting holes are provided at intervals along the circumference on the end face of the rotary block, and the rotary limiting posts are limited to passing through the corresponding rotary limiting holes.

[0013] As an improvement of the rotary fabric quick positioning fixture of this utility model, the base includes a base plate, a limiting plate and a top plate. The limiting plate is stacked on the base plate, and the top plate is located directly above the limiting plate and is spaced apart from the limiting plate to form the rotation space.

[0014] As an improvement of the rotary fabric quick positioning fixture of this utility model, the top surface of the base is provided with two pairs of angle limiting grooves, each angle limiting groove is arranged along the radial direction of the base, and the knob is provided with two angle limiting posts, each angle limiting post switching between the two slots of its corresponding pair of angle limiting grooves.

[0015] As an improvement of the rotary fabric quick positioning fixture of this utility model, the knob includes a rotary cap and a fixed sleeve. The fixed sleeve is fixed between the rotary cap and the rotating block. The upper end of the base is rotatably sleeved on the fixed sleeve. The rotary cap is located outside the base and is rotatably limited by the base.

[0016] Compared with the prior art, the rotary fabric covering quick positioning fixture of this utility model, by rotating and connecting a rotating block inside the base, and limiting and connecting multiple sliders distributed at intervals along the circumference of the base below the rotating block, allows the operator to manually turn the knob to drive the rotating block to rotate within the rotation space of the base, thereby causing the sliders to slide. This enables the corresponding ejector pin to quickly switch between two states: extended outside the base and retracted inside the base. This allows for quick positioning of the fabric covering outside the housing, which not only saves time and effort and provides accurate positioning, but also improves the efficiency and quality of the housing fabric covering process.

[0020] Reference Figures 1 to 14 A rotary fabric quick positioning fixture includes a base 1. A rotating block 4 is rotatably connected within the rotation space 14 of the base 1. A knob 53 is fixed on the rotating block 4. The knob 53 passes through the base 1 and extends outside the base 1. Multiple sliders 2 are connected to the lower limit of the rotating block 4. All sliders 2 are distributed at intervals along the circumference of the base 1. A pin 3 is fixedly connected to the outer side of each slider 2 along the radial direction of the base 1. Each slider 2 is slidably connected to the base 1 along the radial direction of the base 1 to realize the switching between the corresponding pin 3 extending outside the base 1 and retracting inside the base 1.

[0021] Reference Figures 1 to 7The seat 1 includes a base plate 13, a limiting plate 12, and a top plate 11. The limiting plate 12 is stacked on the base plate 13, and the top plate 11 is located directly above the limiting plate 12 and spaced apart from the limiting plate 12 to form the rotation space 14. Specifically, both the base plate 13 and the limiting plate 12 are flat cylindrical. The bottom of the base plate 13 has an annular groove 132, and multiple positioning pins 131 are vertically arranged on the base plate 13. The multiple positioning pins 131 pass through the limiting plate 12, positioning and connecting the limiting plate 12 and the base plate 13. The limiting plate 12 forms the bottom of the rotation space 14. The top surface of the limiting plate 12 (i.e., the bottom of the rotation space 14) has multiple sliding grooves 121. These sliding grooves 121 are distributed circumferentially along the limiting plate 12. Each sliding groove 121 is elongated and arranged radially along the limiting plate 12. The bottom of each sliding groove 121 is along the axis of the seat 1 and the limiting plate 12. A long, narrow sliding limit groove 124 is provided radially. The bottom plate 13 forms the bottom of the sliding limit groove 124. On the outer wall of the seat body 1 (i.e., on the outer wall of the limit plate 12), there are through holes 122 at positions opposite to all the sliding grooves 121 for the corresponding ejector pins 3 to pass through. Multiple rotating limit posts 123 are vertically fixed in the rotation space 14. The lower end of each rotating limit post 123 is vertically inserted into the limit plate 12, and the upper end of the rotating limit post 123 is vertically inserted into the top plate 11, so that the top plate 11 and the limit plate 12 always maintain a certain distance to form the rotation space 14 of the seat body 1. The top plate 11 is a flat ring. On the top of the top plate 11 (i.e., on the top surface of the seat body 1), there are two pairs of angle limit grooves 111. Each angle limit groove 111 is long and narrow and is arranged radially along the top plate 11. The same pair of angle limit grooves 111 are concentrated at the same end of the top plate 11.

[0022] Reference Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The rotating block 4 is generally in the shape of a flattened ring. The rotating block 4 is located within the rotating space 14. The end face of the rotating block 4 is provided with a plurality of elongated arc-shaped sliding limit holes 42 and a plurality of elongated arc-shaped rotating limit holes 41. All the sliding limit holes 42 are inclined along the circumference of the rotating block 4 and are distributed at intervals. All the rotating limit holes 41 are arranged at intervals along the circumference of the rotating block 4. All the rotating limit holes 41 are arranged along the edge of the rotating block 4 and are distributed in a circle around all the sliding limit holes 42. All the rotating limit posts 123 are correspondingly limited and pass through all the rotating limit holes 41 so that the rotating block 4 can be limited to rotate within the rotating space 14.

[0023] Reference Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8and Figure 9 All the sliders 2 are slidably disposed in all the slide grooves 121. One end of the ejector pin 3 is fixedly inserted into the slider 2, and the other end of the ejector pin 3 passes through the corresponding through hole 122 on the side wall of the limiting plate 12. A sliding post 31 is vertically inserted on each slider 2. The upper end of the sliding post 31 is limited to pass through the corresponding sliding limiting hole 42 so that the rotating block 4 is linked and limited to all the sliders 2. The part of each sliding post 31 that passes through the corresponding slider 2 and extends beyond the slider 2 is limited to extend into the corresponding sliding limiting groove 124 so that the slider 2 can slide stably in the corresponding slide groove 121. A locking notch 311 is provided on the side wall of the sliding post 31. A locking adjusting screw 21 is threadedly connected to the side of the slider 2 away from the corresponding ejector pin 3. The locking end of the locking adjusting screw 21 is limited to cooperate with the locking notch 311 so as to adjust the position and tightness of the sliding post 31.

[0024] Reference Figure 2 , Figure 3 , Figure 4 , Figure 10 and Figure 11 The knob 53 includes a knob cap 5 and a fixing sleeve 51. The fixing sleeve 51 is fixed between the knob cap 5 and the rotating block 4. The knob cap 5 is fixedly connected to the fixing sleeve 51 and the rotating block 4 by a plurality of fixing studs 52. The upper end of the base 1 is rotatably sleeved on the fixing sleeve 51. In this embodiment, the top plate 11 is sleeved on the fixing sleeve 51. The knob cap 5 is located outside the base 1 and is rotatably limited by the base 1. The knob cap 5 of the knob 53 is provided with two angle limiting posts 6. The two angle limiting posts 6 are distributed at the left and right ends of the knob cap 5. Each angle limiting post 6 switches between the two slots of its corresponding pair of angle limiting grooves 111.

[0025] Reference Figures 1 to 14 The method of using this utility model of rotary fabric quick positioning fixture is as follows: Place the assembled carrier 8 (the carrier 8 is formed by fixing and assembling a hemispherical shell 81 and a hemispherical simulation part 82 into a sphere) on the positioning seat 7, so that the top of the positioning seat 7 is inserted into the bottom hole of the simulation part 82. Place the entire positioning fixture on top of carrier 8 (e.g.) Figure 13 As shown), the edge of the top hole 811 at the top of the housing 81 is located in the bottom groove 132 at the bottom of the base plate 13. At this time, all the ejector pins 3 are retracted into the corresponding through holes 122 on the side wall of the limiting plate 12. A cloth 83 is fitted together on the positioning fixture, the carrier 8 and the positioning seat 7. The position of the cloth 83 is adjusted so that the upper end of the cloth 83 is fitted on the positioning fixture. Manually rotate the cap 5 counterclockwise. The cap 5 drives the rotating block 4 to rotate through the fixed sleeve 51. Under the limiting action of the rotating limit post 123, the rotating block 4 is limited to rotate within the rotation space 14 of the base 1. On the one hand, as the cap 5 rotates, the left angle limit post 6 changes from one slot to another slot of the pair of angle limit grooves 111 on the left. At the same time, the right angle limit post 6 changes from one slot to another slot of the pair of angle limit grooves 111 on the right, so that the cap 5, the fixed sleeve 51 and the rotating block 4 rotate at a fixed angle. On the other hand, as the cap 5 rotates, the rotating block 4 drives all the sliders 2 to slide outward in their respective slide grooves 121, so that all the ejector pins 3 extend out of the base 1 together. These ejector pins 3 pass through the cover 83 and fix the upper end of the cover 83, so that the carrier 8, the positioning fixture and the cover 83 can be removed together. When it is necessary to remove the cover 83, manually rotate the cap 5 clockwise. The two angle limit pins 6 switch back to their original slots. The rotating block 4 drives all the sliders 2 to slide towards the center of the seat 1, so that all the pins 3 retract into the seat 1, and the cover 83 can be removed smoothly.

[0026] This utility model's rotary fabric covering quick positioning fixture uses a rotating block 4 connected to the base 1, and multiple sliders 2 spaced apart along the circumference of the base 1 below the rotating block 4. The operator only needs to manually turn the knob 53 to drive the rotating block 4 to rotate within the rotation space 14 of the base 1, thereby causing the sliders 2 to slide. This enables the corresponding ejector pin 3 to quickly switch between two states: extended outside the base 1 and retracted inside the base 1. This allows for quick positioning of the fabric covering 83 covering the housing 81, saving time and effort, providing accurate positioning, and improving the efficiency and quality of the fabric covering process on the housing 81.

[0027] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of protection of the present utility model. Therefore, any equivalent changes made in accordance with the scope of the patent application of the present utility model shall still fall within the scope of the present utility model.
