Description

Technical Field

[0001] This invention belongs to the technical field of clamping devices for conductive ring potting, specifically relating to a vertical pressing clamp for mounting a positioning piece before conductive ring potting, which is particularly suitable for electromechanical systems, industrial equipment and precision instruments that require high-precision positioning. Background Technology

[0002] The core function of a conductive ring is to ensure stable transmission of current, signals, or data during equipment rotation, while preventing wire entanglement. Conductive rings connect rotating and stationary components via sliding contact and are widely used in electromechanical systems, industrial equipment, and precision instruments. Before potting the conductive ring, positioning plates must be installed to ensure accurate positioning of the mandrel and bearing sleeve. The positioning plates are made of silicone plastic, possessing a certain degree of flexibility and strength, which increases the difficulty of installation. The center hole of the positioning plate needs to be installed on the mandrel, and the two wings engage with the inner wall of the bearing sleeve hole to position the mandrel. In existing positioning plate installation processes, problems frequently arise: the positioning plate is not installed correctly—it may be too high or too low on the mandrel, resulting in inconsistent installation and affecting quality; the verticality of the installation is also insufficient—the positioning plate and mandrel cannot maintain a 90-degree angle, affecting the concentricity of the mandrel. In existing technologies, the installation of positioning plates mainly relies on manual operation or simple clamps, which presents the following problems: 1. Manual Pressing Method: When installing the positioning plate, after slipping it onto the mandrel, use the tips of both thumbs to simultaneously press down on the two wings of the positioning plate, visually confirming the installation position. The disadvantages of this method are: the positioning plate may be installed too high or too low, making it impossible to guarantee consistency in its position each time; after slipping the positioning plate onto the mandrel, uneven pressure from the thumbs may prevent the positioning plate from maintaining a 90-degree angle with the mandrel, affecting subsequent operations.

[0003] 2. Handheld clamp method: A flat surface is created with the front end aligned with the pressing area of ​​the positioning piece, a mandrel hole in the center, and a handle at the rear end for gripping and pressing down to install the positioning piece into its fixed position. The disadvantage of this method is that, due to handheld installation, the handle and mandrel cannot be guaranteed to be coaxial during handheld installation, and the positioning piece cannot maintain a 90-degree angle with the mandrel in all directions, affecting subsequent operations.

[0004] None of the methods described above can meet the demands of high-precision, high-efficiency mass production. Therefore, there is an urgent need for a fixture device that can accurately position, ensure perpendicularity, and is easy to operate. Summary of the Invention

[0005] The technical problem solved by this invention is to provide a vertical pressing fixture for installing a positioning piece before potting a conductive ring. This invention aims to solve the problems of inconsistent installation positions and insufficient verticality of the positioning pieces in the prior art, and to achieve a fixture device that is accurate in positioning, fast in installation, and suitable for mass production.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A vertical pressing fixture for installing a positioning plate before potting conductive rings includes a fixture body, positioning clamps and movable clamps, a push rod, a pressing handle, and a positioning pin; The clamp body has a light hole coaxial with the mandrel in the middle; The positioning clamp and the movable clamp are respectively located on both sides of the lower part of the fixture body and are used to clamp onto the bearing sleeve; The lower end of the push rod passes through the light hole of the clamp body, and the upper end is connected to the pressing handle. The push rod has a central screw hole inside. The positioning pin passes through the pressing handle and is screwed into the central screw hole inside the push rod to limit the depth of the positioning piece pressed into the mandrel.

[0007] Further defining the above solution, the positioning clamp is fixedly connected to one side of the lower part of the fixture body by a positioning clamp fixing screw, and the movable clamp is connected to the other side of the lower part of the fixture body by a movable clamp top rod. The movable clamp top rod is threadedly engaged with the fixture body, and the end of the movable clamp top rod is movably connected to the movable clamp.

[0008] Further defining the above solution, the pressing handle adopts an arc plate structure, the inner arc surface of the arc plate structure is used for pressing, the outer arc surface of the arc plate structure is provided with an internal threaded tube for connecting the top rod, and the center of the arc plate structure is provided with a hole for positioning the top pin to pass through.

[0009] Further defining the above solution, the depth to which the positioning pin is screwed into the central screw hole of the push rod is adjustable, and the screwing depth of the positioning pin determines the installation height of the positioning piece, thereby enabling adjustment of the pressing depth of the positioning piece for products of different specifications.

[0010] As a further limitation of the above scheme, the center of the optical hole of the fixture body is coaxial with the center of the mandrel.

[0011] As a further limitation of the above scheme, the fixture material is ordinary carbon steel Q235A.

[0012] Advantages of this invention compared to existing technologies: 1. This solution enables precise and quick installation of positioning plates, effectively solving the problems of positioning plates being installed at different heights or not being kept level in all directions, thus improving the quality of positioning plate installation and production efficiency. 2. This solution can achieve precise positioning: through the coaxial design of the fixture body and the mandrel, it ensures that the positioning pieces are installed in the same position and that the perpendicularity meets the standard; 3. This solution enables efficient mass production: After adjusting the positioning pin once, the installation of multiple positioning pieces can be completed quickly, significantly shortening the production cycle; 4. This solution is easy to operate: the ergonomic design of the push handle reduces operator fatigue and improves installation efficiency; 5. This solution simplifies the installation of the positioning plates, reduces operational steps, shortens the production cycle, and improves work efficiency. 4. This solution is highly versatile: it can be adapted to different models of bearing sleeves and mandrels, and has a wide range of applications. Attached Figure Description

[0017] Please see Figure 1-6 The embodiments of the present invention are described in detail below.

[0018] See Figure 1 As shown, in this embodiment, the vertical pressing fixture for installing the positioning piece before potting the conductive ring includes a fixture body 4, a positioning clamp 6 and a movable clamp 5, a push rod 3, a pressing handle 2, and a positioning pin 1.

[0019] The fixture body 4 has a light hole 4-1 in the middle, and the center of the light hole 4-1 is coaxial with the center of the spindle 12.

[0020] See Figure 1 As shown, the positioning clamp 6 and the movable clamp 5 are respectively disposed on both sides of the lower part of the clamp body 4 and are used to clamp onto the bearing sleeve 10. Specifically, the positioning clamp 6 is fixedly connected to one side of the lower part of the clamp body 4 by a positioning clamp fixing screw 8; the movable clamp 5 is connected to the other side of the lower part of the clamp body 4 by a movable clamp top rod 7, the movable clamp top rod 7 is threaded into the clamp body 4, and the end of the movable clamp top rod 7 is movably connected to the movable clamp 5. By rotating the movable clamp top rod 7, the movable clamp 5 can be clamped onto the bearing sleeve 10.

[0021] See Figure 2 As shown, the lower end of the push rod 3 passes through the light hole 4-1 of the clamp body 4, and the upper end is connected to the pressing handle 2. Specifically, the pressing handle 2 adopts an arc plate structure 2-1. The inner arc surface of the arc plate structure 2-1 is convenient for thumb pressing, and the outer arc surface of the arc plate structure 2-1 is welded with an internally threaded tube 2-2 for connecting the push rod 3. The center of the arc plate structure 2-1 is provided with a hole for the positioning pin 1 to pass through.

[0022] See Figure 2 As shown, the push rod 3 has a central screw hole 3-1 inside; the positioning pin 1 passes through the pressing handle 2 and is screwed into the central screw hole 3-1 inside the push rod 3 to limit the depth of the positioning piece 9 pressed into the mandrel 12.

[0023] Preferably, the depth to which the positioning pin 1 is screwed into the central screw hole 3-1 of the push rod 3 is adjustable. The screwing depth of the positioning pin 1 determines the installation height of the positioning piece 9, thereby enabling adjustment of the pressing depth of the positioning piece 9 for products of different specifications.

[0024] Preferably, the fixture is made of ordinary carbon steel Q235A.

[0025] Working principle: 1. Fixture assembly: Pass the push rod 3 through the light hole of the fixture body 4 and connect it to the pressing handle 2; screw the positioning pin 1 into the center screw hole 3-1 of the push rod 3 to the preset depth; the distance the positioning pin 1 is screwed in will determine the depth of the positioning piece 9 through the mandrel 12. The required depth is different for different products and can be adjusted as needed. 2. Fixture fixing: The bearing sleeve 10 in the product component is supported on the potting fixture 13 and sleeved on the outside of the mandrel 12; hold the fixture and clamp one side of the positioning clamp 6 on the outer circle of the bearing sleeve 10, while the other side of the movable clamp 5 is in a movable state. Rotate the movable clamp top rod 7 to clamp the movable clamp 5 on the other side of the outer circle of the bearing sleeve 10, so that the fixture is firmly fixed on the bearing sleeve 10, ensuring that the fixture body 4 is coaxial with the mandrel 12; 3. Positioning Plate Installation: Place the positioning plate 9 onto the upper end of the mandrel 12, ensuring a tight fit. Press the inner arc of the handle 2 with your thumb. Pressing the handle 2 will drive the push rod 3 to smoothly and vertically press down on the positioning plate 9 until the top of the mandrel 12 contacts the positioning pin 1. At this point, the positioning plate 9 will reach the preset height and remain horizontal, thus installing the positioning plate 9 in the corresponding position on the inner wall of the bearing sleeve. Check the horizontality and installation height of the positioning plate 9 to complete the installation.

[0026] 4. Height adjustment: Adjust the extension length by rotating the positioning pin 1 to adapt to the installation requirements of different products.

[0027] After the fixture is installed and fixed, and the positioning pin 1 is adjusted once, the positioning piece 9 can be accurately positioned and installed horizontally simply by pressing the handle 2. This effectively solves the problems of the positioning piece being installed too high or too low, and the positioning piece not being able to maintain a horizontal position before, after, left, or right, thus improving the installation quality and production efficiency of the positioning piece. At the same time, this solution simplifies the installation work, reduces the number of operation steps during batch installation, shortens the production cycle, and improves work efficiency.
