Description

Technical Field

[0001] This utility model relates to the field of tooling equipment technology, and in particular to a cylindrical positioning tool. Background Technology

[0002] A water resistance thermometer is a device that uses the resistance characteristics of an electrolyte to achieve soft starting or speed regulation of a motor. During production, a water resistance connector needs to be installed at both ends of a cylinder, and the cylinder is filled with electrolyte. Depending on the application, the size of the water resistance thermometer varies, requiring the use of cylinders of different sizes. For ease of production, a longer cylinder is usually produced first, and then cut according to actual needs. In current technology, the cylinder is typically placed directly on a workbench, with one end abutting a baffle. Cutting is then performed at the required length on the cylinder. After cutting, the cylinder needs to be manually removed by a worker, and the cutting process is repeated. While manually limiting the cylinder during cutting is convenient, the cylinder may wobble under external forces, leading to inaccurate cutting positions and ultimately, substandard cylinder dimensions. Furthermore, the need to manually move the cut cylinder after each cut hinders rapid production. Utility Model Content

[0003] In view of the shortcomings of the above-mentioned prior art, this application provides a cylinder positioning fixture that can clamp, limit, and move cylinders of different sizes, ensuring cutting accuracy and improving processing efficiency, and has strong practicality.

[0004] To achieve the above objectives, the present invention employs the following technology:

[0005] A cylindrical positioning fixture includes: a worktable, a positioning component, and a moving component.

[0006] The workbench has an elongated hole at one end along its length. The positioning component includes a baffle located at one end of the workbench and moving along its length. The baffle is U-shaped and its opening faces the center of the workbench. The projection of the inner side of the baffle in the vertical direction is located in the elongated hole, which is used to limit the end of the cylinder. Two support blocks mounted on the workbench are provided on the opening side of the baffle to support the cylinder. A first clamping block is provided above the support blocks and moves in the vertical direction to limit the circumference of the cylinder. The moving component is located between the two support blocks and includes a support frame that moves back and forth between the two support blocks and moves in the vertical direction. Two second clamping blocks are provided on the inner side of the support frame and are symmetrically arranged and move towards each other to clamp the cylinder.

[0007] Furthermore, both sides of the baffle are provided with protrusions, which are sleeved on the first screw. Both ends of the first screw are installed on the connecting plate, which is installed on the worktable. A nut is installed on the first screw and is located on the side of the protrusion away from the worktable. A first spring is sleeved on the first screw, and both ends of the first spring abut against the connecting plate and the protrusion near the center of the worktable, and are always in a compressed state.

[0008] Furthermore, the top of the support block and the bottom of the first clamping block are both V-shaped. Vertically arranged guide rods are provided at both ends of the support block. The guide rods pass through the first clamping block. A connecting rod is provided at the upper end of the first clamping block. The connecting rod passes through the lifting plate. The lifting plate is connected to the moving end of the vertical lifting mechanism. The vertical lifting mechanism is installed on the worktable. A second spring is sleeved on the connecting rod. The two ends of the second spring abut against the lifting plate and the first clamping block respectively, and are always in a compressed state.

[0009] Furthermore, the lifting plate has a through groove along its length at one end near the elongated hole, a slider is slidably fitted in the through groove, a pressure rod is fitted in the slider, a pressure block with a V-shaped bottom cross section is provided at the lower end of the pressure rod, one side of the pressure block is slidably connected to the inside of the baffle in the vertical direction, and a third spring is fitted on the pressure rod, with the two ends of the third spring abutting against the pressure block and the slider respectively, and always in a compressed state.

[0010] Furthermore, sliding grooves are provided on both sides of the through groove, and sliding rods are provided in the sliding grooves along their length, with the sliders fitted onto the sliding rods.

[0011] Furthermore, a second screw is provided at the bottom of the support frame and is sleeved on the vertical rod. The vertical rod is installed on the movable block, and the second screw passes through the movable block and is locked with a nut. The movable block is connected to the moving end of the horizontal linear mechanism, and the horizontal linear mechanism is installed on the worktable.

[0012] Furthermore, the inner side of the second clamping block is V-shaped, and the outer side is provided with an L-shaped rod. The short end of the L-shaped rod is provided with a through groove, and a limiting rod passes through the through groove. The lower end of the limiting rod is installed on the support frame, and the upper end of the L-shaped rod is connected to the moving end of the bidirectional linear mechanism, which is installed on the support frame.

[0013] The advantages of this invention are as follows: the cooperation of the support block and the first clamping block can clamp cylinders of different sizes, preventing them from shifting during the cutting process. The movable baffle limits the end of the cylinder, which can adapt to different cutting lengths and has a wide range of applications. After cutting, the movement of the second clamping block realizes the automatic movement of the cylinder, and the pressure block automatically pushes the cut cylinder into the elongated hole for collection, which improves both automation and efficiency.

[0020] To make the objectives, technical solutions and advantages of the present utility model clearer, the implementation methods of the present utility model will be described in detail below with reference to the accompanying drawings. However, the embodiments described in the present utility model are only some embodiments of the present utility model, and not all embodiments.

[0021] like Figures 1-5 As shown, this example provides a cylindrical positioning fixture, including: a worktable 100, a positioning component 200, and a moving component 300.

[0022] The workbench 100 has an elongated hole 101 at one end along its length for the cut cylinder to pass through. The positioning assembly 200 includes a baffle 201 located at one end of the workbench 100 and moving along its length. The baffle 201 is U-shaped with its opening facing the center of the workbench 100. The projection of the inner side of the baffle 201 in the vertical direction is located in the elongated hole 101, which is used to limit the end of the cylinder. Two support blocks 202 mounted on the workbench 100 are provided on the opening side of the baffle 201 for supporting the cylinder. A first clamping block 203 is provided above the support block 202 and moves vertically to limit the circumference of the cylinder. The moving assembly 300 is located between the two support blocks 202 and includes a support frame 301 that reciprocates between the two support blocks 202 and moves vertically. Two symmetrically arranged and opposing second clamping blocks 302 are provided on the inner side of the support frame 301 for clamping the cylinder and moving it.

[0023] Specifically, both sides of the baffle 201 are provided with protrusions 204, which are sleeved on the first screw 205. Both ends of the first screw 205 are installed on the connecting plate 206, which is installed on the worktable 100. A nut is installed on the first screw 205 and is located on the side of the protrusion 204 away from the worktable 100. A first spring 207 is sleeved on the first screw 205. The two ends of the first spring 207 abut against the connecting plate 206 and the protrusion 204 near the center of the worktable 100, and are always in a compressed state. When a longer cylinder needs to be cut, the nut is rotated to move the nut away from the center of the worktable 100. Under the action of the first spring 207, the baffle 201 will also move synchronously. When a shorter cylinder needs to be cut, the nut is also rotated to move the nut closer to the center of the worktable 100. The nut pushes the baffle 201 to move synchronously, and the first spring 207 is further compressed.

[0024] Specifically, the top of the support block 202 and the bottom of the first clamping block 203 are both V-shaped. The support block 202 has vertically arranged guide rods 208 at both ends, which pass through the first clamping block 203. The upper end of the first clamping block 203 has a connecting rod 209, which passes through the lifting plate 210. The lifting plate 210 is connected to the moving end of the vertical lifting mechanism, which is installed on the worktable 100. A second spring 211 is sleeved on the connecting rod 209. The two ends of the second spring 211 abut against the lifting plate 210 and the first clamping block 203 respectively, and are always in a compressed state. When cutting the cylinder, the vertical lifting mechanism drives the lifting plate 210 to move downward, and the first clamping block 203 moves synchronously, thereby clamping the cylinder. The second spring 211 is also further compressed to prevent the lifting plate 210 from moving downward too far and causing the cylinder to deform.

[0025] Specifically, to facilitate the smooth passage of the cut cylinder through the elongated hole 101, a through groove 212 is provided along the length of the lifting plate 210 near the elongated hole 101. A slider 213 is slidably fitted in the through groove 212, and a pressure rod 214 passes through the slider 213. A pressure block 215 with a V-shaped bottom cross-section is provided at the lower end of the pressure rod 214. One side of the pressure block 215 is slidably connected to the inner side of the baffle 201 in the vertical direction. For example, a T-shaped plate is provided on the inner side of the baffle 201. The pressure block 215 has a T-shaped groove, and a T-shaped pin is provided on the side of the pressure block 215. The T-shaped pin is slidably fitted into the T-shaped groove, so that when the baffle 201 moves, the pressure block 215 also moves synchronously, thus ensuring that the pressure block 215 can always apply pressure to the end of the cylinder. A third spring 216 is sleeved on the pressure rod 214. The two ends of the third spring 216 abut against the pressure block 215 and the slider 213 respectively, and are always in a compressed state. When the lifting plate 210 moves downward, the pressure block 215 will also move downward synchronously, so that the pressure block 215 abuts against the end of the cylinder, and the third spring 216 is further compressed. After the cutting is completed, the pressure block 215 will move downward under the action of the third spring 216, thereby pushing the cut cylinder into the elongated hole 100.

[0026] Specifically, both sides of the through groove 212 are provided with sliding grooves 217, and sliding rods 218 are provided in the sliding grooves 217 along their length direction. The slider 213 is sleeved on the sliding rods 218 to provide guidance for the movement of the pressure block 215.

[0027] Specifically, the support frame 301 has a second screw 303 at its bottom, which is sleeved on the vertical rod 304. The vertical rod 304 is installed on the movable block 305, and the second screw 303 passes through the movable block 305 and is locked with a nut. The movable block 305 is connected to the moving end of the horizontal linear mechanism, which is installed on the worktable 100. In use, the height of the support frame 301 can be adjusted by rotating the nut according to the different sizes of the cylinder, thereby adjusting the height of the second clamping block 302. This ensures that the clamping center of the second clamping block 302 is on the same horizontal line as the clamping center of the first clamping block 202, ensuring stable clamping of the cylinder. After clamping the cylinder, the movable block 305 is moved by the horizontal linear mechanism to move the cylinder.

[0028] Specifically, the inner side of the second clamping block 302 is V-shaped, and the outer side is provided with an L-shaped rod 306. The short end of the L-shaped rod 306 is provided with a through groove 307, and a limiting rod 308 passes through the through groove 307 to guide the movement of the second clamping block 302. The lower end of the limiting rod 308 is mounted on the support frame 301, and the upper end of the L-shaped rod 306 is connected to the moving end of the bidirectional linear mechanism. The bidirectional linear mechanism is mounted on the support frame 301. During clamping, the two second clamping blocks 302 are driven to move towards each other through the bidirectional linear mechanism, thereby clamping the cylinder.

[0029] Since the above are merely preferred embodiments of this utility model and are not intended to limit this utility model, it is obvious that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
