Description

Technical Field

[0001] This utility model relates to the field of automated production line technology, and in particular to a quick changeover positioning device for a linear motor assembly line. Background Technology

[0002] Linear motors, as a high-precision drive component, are widely used in automated equipment. During their production and assembly process, positioning devices are required to precisely clamp and position the motor components or their mounting housings to ensure subsequent assembly accuracy and product quality.

[0003] Existing assembly line positioning devices typically use manual clamps or simple pneumatic grippers for positioning. This method often suffers from unstable clamping force and scattered positioning points when clamping workpieces, causing the workpieces to easily shake or shift during assembly. In other words, the positioning capability is poor and the stability is insufficient, which directly affects the high-precision assembly requirements of linear motors.

[0004] Modern production lines need to be compatible with various linear motors of different specifications and models. When production tasks are switched, the position of the positioning device needs to be adjusted. The traditional adjustment method relies on manual operation, which involves loosening bolts, manually moving the entire fixture base, and then realigning and tightening it. This process is time-consuming and labor-intensive, with low automation, which seriously restricts the changeover efficiency and operational flexibility of the production line.

[0005] Therefore, this utility model proposes a quick changeover positioning device for linear motor assembly lines to address the shortcomings of existing technologies. Summary of the Invention

[0006] In view of the problems of poor clamping and positioning ability, insufficient stability, low flexibility of workstation adjustment and low degree of automation in the existing linear motor assembly line quick change positioning device, as well as the problems of poor clamping and positioning ability, insufficient stability, low flexibility of workstation adjustment operation and low degree of automation when switching between different product models, this utility model aims to provide a linear motor assembly line quick change positioning device with improved structure that can effectively solve the above problems.

[0007] This utility model provides a quick changeover positioning device for a linear motor assembly line, comprising: a processing box, a slider, and a slide rail slidably connected to the slider; the device also includes an adjustment mechanism and a clamping mechanism.

[0008] The adjustment mechanism is designed to enable the device to change quickly. It includes a second motor and a lead screw. The output end of the second motor is connected to the lead screw, which is set parallel to the slide rail and threadedly engages with the slider. This mechanism drives the slider with the processing box fixed on it to slide precisely along the slide rail, thereby achieving automated adjustment of the workstation.

[0009] Furthermore, the clamping mechanism is designed to achieve stable clamping of the workpiece. It is located inside the processing box and includes a motor, a clamping shaft, a mounting box, a push block, and a limiting block. The motor drives the clamping shaft to rotate, and the clamping shaft drives the push block and the limiting block to move radially through the transmission assembly, forming a multi-point clamping structure to automatically and stably clamp or release the mounting box.

[0010] Preferably, the adjustment mechanism further includes a guide block, which is fixed to the bottom of the slider and has a screw groove inside. The lead screw achieves precise thread engagement transmission with the slider through the screw groove, ensuring the smoothness and accuracy of the displacement.

[0011] Preferably, the adjustment mechanism further includes a buffer plate, which is fixed to the side of the slider away from the lead screw. When the slider moves rapidly to the end of its stroke, the buffer plate can contact the positioning point first, effectively absorbing the impact energy and thus protecting the equipment from damage.

[0012] Preferably, in order to achieve precise power transmission, the clamping mechanism further includes a rotating shaft, which is connected to the output end of the first motor, and the clamping shaft is coaxially fixed on the rotating shaft to ensure a stable power output from the first motor to the clamping shaft.

[0013] Preferably, to further improve the stability of the clamping mechanism's transmission system, the clamping mechanism also includes a stabilizing plate, which is fixed inside the processing box. The other end of the rotating shaft is rotatably supported inside the stabilizing plate, effectively preventing the rotating shaft from shaking when rotating at high speed.

[0014] Preferably, the transmission assembly specifically includes a gear disk and a turbine ring. The end of the caliper is fixedly connected to the gear disk to drive it to rotate synchronously. The gear disk meshes with the turbine ring through its toothed structure, thereby efficiently transmitting the rotational motion of the caliper to the turbine ring.

[0015] Preferably, both the push block and the limiting block can be slidably mounted on the turbine ring, and when the turbine ring rotates, they can achieve radial displacement along a preset trajectory, simultaneously tightening towards the center or expanding outward to form a stable three-point clamping structure, thereby realizing automatic clamping and loosening of the mounting box.

[0016] Preferably, in order to improve the adaptability of the device to workpieces of different sizes, the clamping mechanism further includes an L-shaped block, which is rotatably mounted above the limiting block. By rotating the L-shaped block, the effective clamping range can be easily adjusted, thereby enhancing the flexibility of the device in changing its configuration.

[0017] This utility model has the following beneficial effects: 1. This utility model solves the problems of poor workpiece clamping and positioning ability, insufficient stability and low operational flexibility in the prior art by setting a clamping mechanism driven by a motor. The clamping mechanism uses a transmission component to drive the push block and the limit block to move radially to automatically clamp the mounting box. In conjunction with the rotatable L-shaped block, it achieves stable clamping, accurate positioning and flexible adaptation to workpieces of different sizes.

[0018] 2. This utility model solves the problems of cumbersome workstation adjustment and inaccurate positioning when switching between different product models in the prior art by setting an adjustment mechanism driven by a motor. The adjustment mechanism uses the screw to engage with the threaded groove in the guide block to drive the slider with the fixed processing box to slide along the slide rail. This achieves rapid model changeover, automated adjustment and accurate positioning.

[0019] 3. This utility model solves the problems of easy impact and lack of protection during rapid displacement adjustment in the prior art by setting a buffer plate on the slider, thereby achieving buffering and energy absorption, protecting the equipment from damage, and improving the safety of device operation.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please refer to Figures 1 to 5 This utility model provides a rapid changeover positioning device for a linear motor assembly line, which aims to solve the problems of poor positioning capability and insufficient stability when clamping workpieces in the prior art, as well as low flexibility of workstation adjustment when switching between different product models and difficulty in adapting to the rapid changeover requirements of multiple product specifications.

[0024] like Figure 1 , Figure 2 and Figure 4 As shown, a quick changeover positioning device for a linear motor assembly line includes a slider 301 and a processing box 1 fixedly connected to the top of the slider 301. The slider 301 is slidably connected to a slide rail 304. The device also includes an adjustment mechanism 3 disposed below the slider 301 and a clamping mechanism 2 disposed within the processing box 1. The adjustment mechanism 3 is used to drive the slider 301 and the processing box 1 to slide along the slide rail 304, and the clamping mechanism 2 is used to clamp and position the mounting box 208 within the processing box 1. (Refer to...) Figure 4 and Figure 5 The adjustment mechanism 3 includes a second motor 5, a lead screw 303, and a guide block 302. The output end of the second motor 5 is connected to the lead screw 303, which is set parallel to the slide rail 304. The guide block 302 is fixed to the bottom of the slider 301. The guide block 302 has a screw groove 306 inside, and the lead screw 303 is threadedly engaged with the screw groove 306. When the second motor 5 starts, it drives the lead screw 303 to rotate, and through the thread engagement between the lead screw 303 and the screw groove 306, it drives the guide block 302 and the fixedly connected slider 301 to achieve horizontal sliding displacement along the slide rail 304. The adjustment mechanism 3 also includes a buffer plate 305, which is fixed to the side of the slider 301 away from the lead screw 303, and is used to provide buffer when the slider 301 moves to the target position. Reference Figure 2 and Figure 3The clamping mechanism 2 includes a motor 4, a rotating shaft 201, a clamping shaft 202, a mounting box 208, a push block 205, and a limiting block 206. The rotating shaft 201 is connected to the output end of the motor 4, and the clamping shaft 202 is coaxially fixed to the rotating shaft 201. The clamping mechanism 2 also includes a stabilizing plate 209, which is fixed inside the processing box 1. The other end of the rotating shaft 201 is rotatably supported inside the stabilizing plate 209. The clamping mechanism 2 also includes a transmission assembly, which includes a gear disk 203 and a turbine ring 204. The end of the clamping shaft 202 is fixedly connected to the gear disk 203 so that it rotates synchronously. The gear disk 203 meshes with the turbine ring. The turbine ring 204 is rotated, and the push block 205 and the limiting block 206 are slidably mounted on the turbine ring 204. When the turbine ring 204 rotates, it achieves radial displacement along the trajectory on it. When the motor 4 starts, it drives the rotating shaft 201 and the clamping shaft 202 to rotate, which in turn drives the turbine ring 204 to rotate through the gear disk 203. Finally, it drives the push block 205 and the limiting block 206 to move radially to clamp or release the mounting box 208 that contains the equipment to be assembled. The clamping mechanism 2 also includes an L-shaped block 207, which is rotatably mounted above the limiting block 206 to adapt to mounting boxes 208 of different sizes.

[0025] Please refer to Figure 1 , Figure 4 and Figure 5 The adjustment mechanism 3 mainly consists of a second motor 5, a lead screw 303, a guide block 302, and a buffer plate 305. The adjustment mechanism 3 is installed between slide rails 304 and cooperates with the slider 301. The second motor 5 is fixed to the equipment base through a base, and its output end is rotatably connected to the lead screw 303. The lead screw 303 is set parallel to the extension direction of the slide rail 304. Its function is to provide a power source and precision transmission for the horizontal displacement of the entire processing box 1. The guide block 302 is fixedly connected to the bottom of the slider 301 by bolts or other means. Please refer to Figure 5 The guide block 302 has a threaded groove 306 inside. The internal thread profile of the threaded groove 306 is fully engaged with the external thread profile of the lead screw 303. The buffer plate 305 is fixed on the side of the slider 301 away from the lead screw 303. Its material can be elastic materials such as rubber or polyurethane.

[0026] In the assembled state, the bottom groove of the slider 301 slides and engages with the slide rail 304, while the guide block 302 at its bottom is sleeved and engaged with the lead screw 303 through the screw groove 306. When a change of station is required, the motor 5 starts and drives the lead screw 303 to rotate. Due to the threaded engagement between the guide block 302 and the lead screw 303, and the fact that the slider 301 is limited to linear movement by the slide rail 304, the rotation of the lead screw 303 is converted into precise linear sliding of the guide block 302 and the slider 301 along the slide rail 304. This transmission structure of motor-lead screw 303-slider 301 ensures the stability, high repeatability, and rapid response capability of the processing box 1 fixed on the slider 301 when changing stations. When the slider 301 moves quickly to the end of its stroke, the buffer plate 305 will first contact the positioning point or limit structure to absorb the impact energy and protect the equipment from damage.

[0027] As a preferred embodiment, please refer to Figure 2 and Figure 3 The output end of the motor 4 of the clamping mechanism 2 is rotatably connected to the rotating shaft 201, and the clamping shaft 202 is coaxially fixed on the rotating shaft 201, so that the clamping shaft 202 and the rotating shaft 201 rotate synchronously. In a preferred embodiment, the clamping mechanism 2 further includes a stabilizing plate 209, which is fixed inside the processing box 1. The other end of the rotating shaft 201 is rotatably supported inside the stabilizing plate 209 to improve the rotational stability of the rotating shaft 201 and the clamping shaft 202. In a preferred embodiment, the transmission assembly includes a gear disk 203 and a turbine ring 204. The end of the clamping shaft 202 is fixedly connected to the gear disk 203, the gear disk 203 meshes with the turbine ring 204, and the turbine ring 204 is rotatably disposed on the top of the processing box 1. In a preferred embodiment, both the push block 205 and the limiting block 206 can be slidably mounted on the turbine ring 204, and when the turbine ring 204 rotates, they can achieve radial displacement along the trajectory on it to clamp or release the mounting box 208. In a preferred embodiment, the clamping mechanism 2 also includes an L-shaped block 207, which is rotatably mounted above the limiting block 206 to accommodate mounting boxes 208 of different sizes.

[0028] Working principle: Before assembly, place the equipment to be assembled into the mounting box 208 in the clamping mechanism 2. Start motor 4. When motor 4 starts, it will drive the rotating shaft 201 at its output end to rotate. The rotating shaft 201 will synchronously drive the clamping shaft 202 to rotate. At this time, during the rotation of the clamping shaft 202, it will drive the turbine ring 204 connected to the top of the processing box 1 to rotate. During this process, the other end of the rotating shaft 201 will also rotate within the stabilizing plate 209. The stabilizing plate 209 can stabilize the rotating shaft 201 and the clamping shaft 202 inside the processing box 1. When the turbine ring 204 rotates, the turbine ring 204 at its top also rotates. At this time, the turbine ring 204... 4. The push block 205 on the outer wall will move and press towards the center of the gear disk 203 along the trajectory of the turbine ring 204, forming a three-jaw clamping and positioning locking structure with the two limit blocks 206 on the turbine ring 204, thereby clamping and fixing the mounting box 208. When the clamping shaft 202 is rotated in the opposite direction, the gear disk 203 rotates in the opposite direction, and the push block 205 on the turbine ring 204 moves outward to contact and press and fix the mounting box 208. During the process, the L-shaped block 207 above the limit block 206 can be rotated and adjusted according to the size of the mounting box 208 to improve flexibility and solve the problems of poor positioning ability, insufficient stability and low operation flexibility in the clamping and positioning link of the assembly machine. Furthermore, when it is necessary to adjust the sliding displacement of the processing box 1, the motor 2 5 drives the adjustment mechanism 3 at the bottom of the processing box 1. The lead screw 303 in the adjustment mechanism 3 rotates and engages with the screw groove 306 on the inner wall of the guide block 302 at the bottom of the slider 301, causing the slider 301 to slide along the slide rail 304 to achieve horizontal displacement adjustment. Before the slider 301 moves to the target position, the buffer plate 305 first contacts the positioning point to meet the assembly position requirements of different models of linear motors. The buffer structure protects the equipment during rapid displacement and can adapt to the assembly positioning requirements of products of various specifications.
