Description

Technical Field

[0001] This utility model relates to the field of communication equipment processing technology, specifically to a clamp for spraying communication shells that facilitates positioning. Background Technology

[0002] In the manufacturing process of communication equipment, shell coating is a crucial step in ensuring product appearance quality and protective performance. Traditional coating fixtures typically employ a fixed structure design with an adjustable clamping range, resulting in significant limitations in actual production. When faced with communication shells of varying lengths, operators must frequently change matching fixtures to achieve proper clamping and positioning, increasing equipment changeover time and reducing production line efficiency. Furthermore, the transmission components of existing fixtures are directly exposed to the coating environment, making it easy for paint particles to adhere to the screw and threaded surfaces, leading to increased transmission resistance and even jamming over time. While some fixtures employ simple dust cover structures, their fixing methods often hinder the convenience of daily maintenance. Therefore, there is an urgent need to develop a coating fixture system with an adaptive clamping range, reliable protection of transmission components, and ease of maintenance to meet the diverse production needs of modern communication equipment.

[0003] To address the aforementioned issues, existing technologies urgently need improvement. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a convenient positioning fixture for spraying communication housings. It has the advantages of adjustable clamping range to accommodate different specifications of communication housings, reduced equipment changeover time, and improved production line efficiency.

[0005] This application provides a fixture for spraying communication housings that facilitates positioning, and the technical solution is as follows:

[0006] The device includes a base, and a clamping assembly is provided on the top of the base. The clamping assembly includes a dual-axis motor, which is located at the center of the top of the base. Both output ends of the dual-axis motor are provided with screws. The screws are threadedly connected to a threaded cylinder. A movable plate is fixedly connected to the outside of the threaded cylinder. Both ends of the bottom of the movable plate are provided with sliders. Both ends of the top left side of the base are provided with grooves that match the sliders. Both ends of the top of the movable plate are provided with support plates.

[0007] Furthermore, this application also proposes that a limiting plate is fixedly sleeved on the surface of the dual-axis motor, and the bottom of the limiting plate is fixedly connected to the base.

[0008] Furthermore, this application also proposes that a protective cover be fitted onto the surface of the screw and the threaded sleeve, and that the bottom of the protective cover be in contact with the base.

[0009] Furthermore, this application also proposes that fixing plates are fixedly connected to both sides of the front and back of the protective cover, and the inner cavity of the fixing plates is fixedly connected to the base by fixing bolts.

[0010] Furthermore, this application also proposes that a support frame is fixedly connected to the inner side of the support plate, and the other end of the support frame is fixedly connected to the movable plate.

[0011] Furthermore, this application also proposes that mounting holes are provided at the four corners of the base cavity, and the four mounting holes are of the same size.

[0012] As can be seen from the above, the communication shell spraying fixture and its protective components provided in this application are easy to position. The screw driven by the dual-axis motor drives the moving plate and the support plate to adjust their positions, thereby realizing the adaptive adjustment of the clamping range. This solves the problem of low production efficiency caused by the non-adjustable clamping range of traditional fixtures. It has the advantages of adjustable clamping range to adapt to different specifications of communication shells, reduced equipment changeover time and improved production line efficiency.

[0018] The following drawings will disclose several embodiments of this utility model. For clarity, many practical details will be described in the following description. However, it should be understood that these practical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these practical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0019] Please see Figure 1-3 In existing technologies, the spraying of communication casings requires the use of fixtures for positioning and fixation. Traditional fixtures have a fixed structure and can only accommodate casings of a single specification. When dealing with products of different lengths, operators must frequently change fixtures, leading to decreased work efficiency and increased equipment changeover costs. Especially in small-batch, multi-variety production scenarios, this rigid structure severely restricts the flexibility of the production line.

[0020] To address these issues, researchers discovered that insufficient clamp adjustment capability was the core problem leading to poor adaptability. Analysis of the transmission mechanism revealed that traditional single-axis drives could only achieve unilateral displacement, failing to create symmetrical clamping actions. Therefore, a bidirectional synchronous drive scheme was proposed, using a central power source to simultaneously control the clamping mechanisms on both sides, ensuring both positioning symmetry and continuous length adjustment.

[0021] Therefore, this application proposes a spraying fixture including a base 1, with a clamping assembly 2 mounted on the top of the base 1. The clamping assembly 2 includes a dual-axis motor 201 located at the center of the top surface of the base 1, with two output ends of the motor connected to screws 2010. A threaded cylinder 2011 is mounted on the surface of the screws 2010, and a movable plate 206 is fixed to the outside of the threaded cylinder 2011. Slider blocks 207 are provided at both ends of the bottom of the movable plate 206, and grooves 3 that mate with the sliders 207 are opened at both ends of the left side of the top surface of the base 1. Support plates 205 are provided at both ends of the top surface of the movable plate 206.

[0022] Among them, the dual-axis motor 201 refers to a drive device with a bidirectional synchronous output shaft, which can be implemented using a dual-output-shaft stepper motor or a servo motor to ensure synchronous operation of the transmission systems on both sides. The screw 2010 refers to a transmission rod with external threads, which can be implemented using a trapezoidal thread or a ball screw structure to convert rotational motion into linear displacement. The threaded sleeve 2011 refers to a sleeve component with internal threads, which can be implemented using a copper alloy bushing or an engineering plastic bushing, and transmits power through meshing with the screw 2010. The moving plate 206 refers to a sliding component that supports the support plate 205, which can be implemented using an aluminum alloy profile or a welded steel plate structure, and forms a sliding pair with the base 1 through the bottom slider 207. The groove 3 refers to a guide structure that restricts the movement trajectory, which can be implemented using a dovetail groove or a linear guide structure to ensure that the moving plate 206 translates along a set direction. The support plate 205 refers to a support component that directly contacts the workpiece, which can be implemented using a polyurethane-coated metal frame structure to avoid damage to the outer shell surface.

[0023] Specifically, when the communication housing is placed in the support plate 205 area, the dual-axis motor 201 is activated to drive the screws 2010 on both sides to rotate synchronously. The meshing action of the screws 2010 and the threaded cylinder 2011 pushes the moving plate 206 to move outward along the slide groove 3, causing the support plates 205 on both sides to expand synchronously. The opening and closing range of the support plates 205 can be controlled by adjusting the motor rotation direction, thereby adapting to the clamping requirements of housings of different lengths. The cooperation between the slider 207 and the slide groove 3 ensures the stability of the moving plate 206's movement trajectory and avoids skewing and jamming.

[0024] Compared to existing technologies, traditional clamps, which rely on manually adjusted bolts or single-sided cylinder drives, suffer from low adjustment precision and asynchrony between the two sides. This solution utilizes a combination of a dual-axis motor 201 and a screw 2010 to achieve precise symmetrical displacement control, ensuring both clamping stability and continuous adjustment capability. Existing technologies require multiple clamps to handle products of different specifications, while this solution achieves universal clamping functionality through an adjustable support plate 205 structure.

[0025] Through the above technical solution, this application achieves rapid adaptation to communication shells of different lengths, eliminating the need for frequent fixture changes. The adoption of an electromechanical integrated drive significantly improves adjustment efficiency and ensures clamping and positioning accuracy. The symmetrical support plate 205 structure effectively disperses clamping stress, preventing shell deformation and damage.

[0026] This application further proposes that a limiting plate 202 is fixedly sleeved on the surface of the dual-axis motor, and the bottom of the limiting plate 202 is fixedly connected to the base 1.

[0027] Among them, the limiting plate 202 refers to the ring or plate-shaped structure set around the outer surface of the motor. Specifically, it can be achieved by stamping metal sheet and then welding or bolting it, and is used to constrain the axial displacement of the motor during operation.

[0028] The fixed connection of the base 1 refers to the rigid connection between the limiting plate 202 and the base 1, which can be achieved by welding, riveting or bolting, to eliminate the vibration transmission during motor operation and enhance the overall structural stability.

[0029] Specifically, during the rotation of the screw 2010 driven by the dual-axis motor 201, the axial reaction force generated by the motor is absorbed by the limiting plate 202 and transmitted to the base 1. Since the limiting plate 202 is fixedly connected to the base 1, the motor housing cannot experience axial displacement, thus ensuring the synchronous rotation accuracy of the screws 2010 on both sides. This structure ensures that the movement trajectory of the threaded cylinder 2011 on the screw 2010 remains linear, avoiding deviations in the clamping position of the support plate 205 caused by motor displacement.

[0030] Compared with existing technologies, the drive motor of traditional clamps is usually only fixed to the surface of the base 1 by bolts. It is prone to slight displacement during frequent start-stop or sudden load changes, resulting in inaccurate positioning of the clamping mechanism. In contrast, this solution uses the rigid connection between the limiting plate 202 and the base 1 to completely constrain the motor in the preset position, fundamentally eliminating the cumulative error of moving parts.

[0031] Through the above technical solution, this application achieves position locking of the drive motor under high-speed operation, ensuring that the symmetrical opening action of the clamping component 2 on the communication shell is always under control. This structure effectively solves the problem of uneven clamping force distribution caused by motor displacement, enabling the fixture to stably adapt to shells of different lengths without repeated calibration.

[0032] This application further proposes that the screw 2010 and the threaded sleeve are fitted with a protective cover 204, and the bottom of the protective cover 204 is in contact with the base 1.

[0033] The protective cover 204 refers to the shell structure covering the screw 2010 and the threaded sleeve. It can be made of metal or engineering plastic and is used to prevent paint or dust splashed during the spraying process from entering the interior of the threaded drive structure. The bottom of the protective cover 204 contacts the base 1, meaning that the lower end face of the protective cover 204 forms a planar contact with the upper surface of the base 1. This can be achieved by setting a sealing gasket or machining a planar fit structure to prevent foreign objects from entering the meshing area of ​​the screw 2010 and the threaded sleeve from the bottom gap.

[0034] Specifically, the protective cover 204 forms a physical isolation barrier by enclosing the transmission components of the screw 2010 and the threaded sleeve. When the dual-axis motor 201 drives the screw 2010 to rotate, the protective cover 204 can effectively prevent paint particles or environmental dust generated during the spraying operation from adhering to the thread surface. The way the bottom of the protective cover 204 contacts the base 1 can prevent foreign objects from entering the transmission structure through the bottom gap, thereby maintaining the cleanliness of the threaded pair and ensuring the smooth sliding of the moving plate 206 in the slide groove 3.

[0035] Compared to existing technologies, the screw transmission structure of traditional clamps (2010) is typically directly exposed to the spraying environment. The threaded pair is susceptible to paint solidification or dust accumulation, leading to jamming of the clamping mechanism or a decrease in positioning accuracy. This solution, by adding a protective cover (204), spatially isolates contaminants from contact with the transmission components, thus solving the problem of motion failure caused by foreign object intrusion into the threaded pair.

[0036] Through the above technical solution, this application can effectively avoid the formation of hard lumps of sprayed material on the surface of the screw 2010 and the threaded sleeve, prevent the clamping mechanism from being unable to adjust due to the jamming of the threaded pair, thereby improving the adaptability of the clamp to communication shells of different lengths and the stability of long-term use.

[0037] This application further proposes that the protective cover 204 has fixed plates 208 fixedly connected to both sides of the front and back sides, and the inner cavity of the fixed plate 208 is fixedly connected to the base 1 by fixing bolts 209.

[0038] The fixing plate 208 refers to the plate-shaped structure connected to the protective cover 204. Specifically, it can be made of metal sheet stamped and welded to both sides of the protective cover 204 to provide a connection interface with the base 1. The fixing bolt 209 refers to the fastener that passes through the fixing plate 208 and is threaded to the base 1. Specifically, it can be a hexagonal head bolt with a nut to achieve detachable fixing, which facilitates the installation and removal of the protective cover 204.

[0039] Specifically, the protective cover 204 covers the screw 2010 and threaded cylinder 2011 through fixing plates 208 on both sides. The fixing plates 208 have through holes, and the fixing bolts 209 pass through the through holes and are tightened into the pre-set threaded holes of the base 1, so that the protective cover 204 and the base 1 form a rigid connection. This structure maintains the stability of the protective cover 204 while allowing the protective cover 204 to be quickly removed by removing the fixing bolts 209, so as to maintain or replace the internal screw 2010 or threaded cylinder 2011.

[0040] Compared to existing technologies, traditional clamps often employ integrated welding or non-removable snap-fit ​​designs for their protective structures, requiring complete removal of the protective device for maintenance, which is complex and time-consuming. This solution simplifies the assembly and disassembly process while ensuring protective performance through the combination of a fixing plate 208 and bolts.

[0041] Through the above technical solution, this application achieves a detachable fixation between the protective cover 204 and the base 1, which avoids foreign objects from entering the screw 2010 transmission mechanism during the spraying process and causing jamming. At the same time, it facilitates the regular cleaning of paint residue accumulated inside the protective cover 204, reduces the equipment failure rate and extends its service life.

[0042] This application further proposes that a support frame 203 is fixedly connected to the inner side of the support plate 205, and the other end of the support frame 203 is fixedly connected to the movable plate 206.

[0043] Among them, the support frame 203 refers to the rigid structural component that connects the support plate 205 and the movable plate 206. Specifically, it can be made of metal profiles or engineering plastics and is used to distribute the load and maintain the structural stability when the support plate 205 is subjected to external forces.

[0044] Among them, the fixed connection refers to the rigid connection between the support frame 203, the support plate 205, and the movable plate 206 through welding, bolt fastening, or integral molding. Specifically, it can be achieved by using bolts with positioning holes to ensure that the support frame 203 will not undergo relative displacement when subjected to force.

[0045] Specifically, when the movable plate 206 is driven by the screw 2010 to move laterally, the support frame 203, as an extension support structure of the support plate 205, can synchronously adjust its position along with the movable plate 206. During the process of the support plate 205 contacting the inner wall of the communication housing and applying clamping force, the support frame 203 forms a triangular stable structure, effectively suppressing the deformation of the support plate 205 caused by uneven force. Through the double fixed connection between the support frame 203 and the movable plate 206, the clamping force is evenly transmitted to the base 1, avoiding structural failure caused by localized stress concentration.

[0046] Compared with existing technologies, the support plate 205 of traditional clamps usually adopts a cantilever structure design, which is prone to elastic deformation during clamping, resulting in a decrease in clamping accuracy. In contrast, this solution adds a support frame 203 to form a composite support structure, which significantly improves the bending stiffness of the support plate 205 while allowing it to move freely, so that the contact surface between the support plate 205 and the communication shell always maintains a uniform pressure distribution during clamping.

[0047] Through the above technical solution, this application effectively solves the problem of elastic deformation of the support plate 205 during clamping operations, ensuring that communication shells of different sizes can obtain stable internal support during clamping. The dual fixing structure of the support frame 203 and the moving plate 206 further enhances the rigidity of the overall fixture, enabling the clamping assembly 2 to maintain its initial positioning accuracy even after long-term repeated use.

[0048] This application further proposes that mounting holes 4 are provided at the four corners of the inner cavity of the base 1, and the four mounting holes 4 are of the same size.

[0049] Among them, mounting hole 4 refers to the hole structure used to fix the clamp. Specifically, it can be implemented by through hole or threaded hole, and is connected to external equipment by bolt or screw, so as to fix base 1.

[0050] Among them, "consistent size" means that the diameter and depth of the four mounting holes 4 are the same. This can be achieved by using standardized processing techniques, such as using drill bits of the same specification, to ensure that the size of the mounting holes 4 is uniform.

[0051] Specifically, four mounting holes 4 are machined at the four corners of the inner cavity of the base 1, and all mounting holes 4 have the same diameter and depth. When the fixture needs to be fixed to the worktable or equipment surface, it can be connected by bolts passing through the mounting holes 4. Since the four mounting holes 4 are evenly distributed at the four corners of the base 1 and are of the same size, there is no need to distinguish between different hole positions during installation, and fasteners of the same specification can be used directly to complete the fixation. For example, the mounting holes 4 can be designed as through holes with a diameter of 8 mm, used with M8 bolts to ensure a stable connection between the base 1 and the external equipment.

[0052] Compared with existing technologies, the mounting holes 4 of traditional fixtures often result in low installation efficiency due to uneven distribution or size differences, and the inconsistent fastener specifications can easily lead to installation misalignment. This solution simplifies the installation process and avoids positioning errors caused by hole deviations through the design of standardized mounting holes 4 symmetrically distributed at the four corners. At the same time, the uniform size reduces the complexity of fastener selection.

[0053] Through the above technical solution, this application achieves rapid and precise installation of the fixture base 1, solving the problem of unstable fixation caused by unreasonable design of the mounting holes 4 in traditional fixtures. The uniform distribution of the mounting holes 4 enhances the uniformity of force on the base 1, while the consistent size improves assembly efficiency, ensuring that the fixture remains stable during spraying operations and avoiding displacement caused by vibration or external forces.

[0054] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
