[0001] The present invention relates to the field of automobile parts processing, and in particular to a positioning tool for processing and manufacturing new energy automobile parts. Background Art

[0002] New energy vehicle parts are the units that make up the whole new energy vehicle parts processing, as well as the products that serve the auto parts processing. New energy vehicle parts are mostly irregular in shape and have relatively uneven surfaces. Positioning tooling refers to the process equipment used to position and fix new energy vehicle parts during the processing and manufacturing of new energy vehicle parts.

[0003] However, most of the current positioning tools are difficult to fit closely to the workpiece due to the irregular shape of the workpiece, and the limiting fixation of the workpiece is not effective. At the same time, it is not easy to limit and fix the top of the workpiece, which will cause the workpiece to slide up and down during processing, which is not stable enough and makes the manufactured products substandard.

[0009] Furthermore, it also includes a reinforcement mechanism, which is arranged on the connecting rod, and the reinforcement mechanism includes a net plate, a rubber net, a fixing frame and a rubber ring. The lower part of the connecting rod is fixedly connected to the net plate, and the net plate is located below the placement shell. The eight clamping rods all pass through the net plate, and the bottom of the net plate is fixedly connected to the rubber net. The eight clamping rods all pass through the rubber net. The lower parts of the eight clamping rods are fixedly connected to the fixing frames, and the eight fixing frames are located below the net plate.

[0010] Furthermore, it also includes a pressing mechanism, which is arranged on the clamping rod, and the pressing mechanism includes a pressing rod, a pressing block, a limiting block, a displacement frame, a horizontal spring and a limiting rod. The tops of the eight clamping rods are slidably connected to the pressing rod, and the tops of the eight pressing rods are fixedly connected to the pressing blocks. Two limiting blocks are fixedly connected to each of the clamping rods, and the two limiting blocks form a group. The displacement frame is slidably connected between the two limiting blocks in each group, and a horizontal spring is connected between each limiting block and the displacement frame. A limiting rod is fixedly connected to the inner wall of each displacement frame, and a limiting groove is opened on the upper part of each pressing rod, and the end of the limiting rod away from the displacement frame is in contact with the limiting groove.

In this way, the clamping rods are pushed to limit the workpiece by the elastic force of the clamping spring, and irregularly shaped workpieces can be effectively limited and fixed, thereby making the workpiece more stable in the subsequent processing process and making the manufactured products more in line with the standards.

[0015] When the placing plate drives the connecting rod to move downward, the connecting rod will drive the circular piston to move downward, so that the extrusion block can limit and fix the workpiece. In this way, the elastic force of the extrusion spring pushes the extrusion block to limit the workpiece, which can make the extrusion block better fit the workpiece, thereby more effectively limiting and fixing irregularly shaped workpieces, making the workpiece more stable in subsequent processing, and further making the manufactured products more in line with standards.

[0016] When the clamping spring drives the clamping rod to move in the direction close to the placement plate, the limit rod will disengage from the pressure rod, so that the limit rod no longer limits the pressure rod. In this way, the displacement frame is pushed by the horizontal spring to further limit and fix the workpiece, and the top of the workpiece is limited and fixed by the pressure block, so that the workpiece is not easy to move up and down during the processing, thereby being able to limit and fix the workpiece more stably.

DETAILED DESCRIPTION

[0032] The standard parts used in the present invention can all be purchased from the market, and special-shaped parts can all be customized according to the description in the specification and drawings. The specific connection methods of each part all adopt conventional means such as mature bolts, rivets, welding, and bonding in the prior art, which will not be described in detail here.

[0033] Embodiment 1: A positioning tool for processing and manufacturing new energy vehicle parts, such as Figure 1-Figure 13 As shown, it includes a base 1, a placement shell 2 and a clamping mechanism. The base 1 is connected to the placement shell by bolts, and the clamping mechanism is arranged on the placement shell 2.

[0034] The placing shell 2 includes a placing plate 31, a connecting rod 311, a vertical spring 32, an annular cone 33, a guide block 34, a clamping rod 35 and a clamping spring 36. The placing shell 2 is slidably connected with a connecting rod 311, and the top of the connecting rod 311 is connected to the placing plate 31 by bolts. A workpiece 21 is placed on the placing plate 31. A vertical spring 32 is connected between the placing plate 31 and the bottom of the inner wall of the placing shell 2 by a hook. The vertical spring 32 is sleeved on the connecting rod 311. The lower part of the connecting rod 311 is slidably connected with an annular cone 33, and an inclined surface is provided on the annular cone 33. Eight guide blocks 34 are slidably connected to the placing shell 2, and each of the guide blocks 34 is connected to a clamping rod 35 by bolts. The annular cone 33 is in contact with the bottom of the eight clamping rods 35, and a clamping spring 36 is connected between each of the guide blocks 34 and the placing shell 2 by a hook.

[0035] At first, the annular cone 33 presses against the bottom end of the clamping rod 35, and the clamping spring 36 is in a compressed state. First, the staff places the workpiece 21 on the placement plate 31. Under the weight of the workpiece 21, the placement plate 31 will move downward, and the vertical spring 32 will be compressed. The placement plate 31 moves downward, which will drive the connecting rod 311 to move downward. The downward movement of the connecting rod 311 will drive the annular cone 33 to move downward. The annular cone 33 no longer presses against the bottom end of the clamping rod 35, and the clamping spring 36 will rebound. The rebound of the clamping spring 36 will drive the eight guide blocks 34 to move in the direction close to the placement plate 31. The movement of the guide blocks 34 will drive the eight clamping rods 35 to move in the direction close to the placement plate 31. The eight clamping rods 35 will respectively contact different parts of the workpiece 21, so that the clamping The rod 35 limits and fixes the workpiece 21. In this way, the clamping rod 35 is pushed to limit the workpiece 21 through the elastic force of the clamping spring 36, and the irregularly shaped workpiece 21 can be effectively limited and fixed, so that the workpiece 21 is more stable in the subsequent processing process, and the manufactured product is more in line with the standards. When the workpiece 21 is processed, the staff will take away the workpiece 21, and the vertical spring 32 will reset. The reset of the vertical spring 32 will drive the placement plate 31 to move upward and reset. The reset of the vertical spring 32 will drive the connecting rod 311 to move upward and reset. The upward movement and reset of the connecting rod 311 will drive the annular table 33 to move upward and reset. The reset of the annular table 33 will push the eight clamping rods 35 to move in the direction away from the placement plate 31, and the clamping spring 36 will reset.

[0036] Embodiment 2: Based on embodiment 1, Figure 1-Figure 8As shown, a hydraulic mechanism is also included, which is arranged on the base 1. The hydraulic mechanism includes a hydraulic cylinder 41, a circular piston 42, a hydraulic pipe 43, a piston cylinder 44, a piston block 45, an extrusion block 46 and an extrusion spring 47. The hydraulic cylinder 41 is connected to the base 1 by bolts, and the circular piston 42 is slidably connected in the hydraulic cylinder 41. The connecting rod 311 is slidably connected to the hydraulic cylinder 41, and the top of the circular piston 42 is fixedly connected to the bottom of the connecting rod 311. The lower part of the hydraulic cylinder 41 is connected to four Hydraulic pipe 43, the hydraulic cylinder 41 is connected to the four hydraulic pipes 43, the placement shell 2 is fixedly connected to the four hydraulic pipes 43, the ends of the four hydraulic pipes 43 away from the hydraulic cylinder 41 are connected to the piston cylinder 44 through a flange, the four piston cylinders 44 are slidably connected to the piston blocks 45, the four piston blocks 45 are slidably connected to the extrusion blocks 46 at one end away from the piston cylinder 44, the four extrusion blocks 46 are connected to the piston blocks 45 through hooks with extrusion springs 47, and the extrusion springs 47 are located in the piston blocks 45.

[0037] Initially, there is a certain amount of hydraulic oil in the hydraulic cylinder 41. When the placement plate 31 drives the connecting rod 311 to move downward, the connecting rod 311 drives the circular piston 42 to move downward. The downward movement of the circular piston 42 pushes the hydraulic oil in the hydraulic cylinder 41 to enter the four piston tubes 44 through the four hydraulic pipes 43 respectively. The hydraulic oil pushes the four piston blocks 45 to move in a direction close to each other. The movement of the piston block 45 drives the extrusion block 46 to move. The four extrusion blocks 46 will contact different parts of the workpiece 21 respectively, and the extrusion spring 47 will be compressed, so that the extrusion block 46 limits and fixes the workpiece 21. In this way, the elastic force of the extrusion spring 47 By pushing the extrusion block 46 to limit the workpiece 21, the extrusion block 46 can better fit the workpiece 21, thereby more effectively limiting and fixing the irregularly shaped workpiece 21, making the workpiece 21 more stable during subsequent processing, and further making the manufactured product more in line with standards. When the workpiece 21 is processed, the staff will take away the workpiece 21, and the connecting rod 311 will drive the circular piston 42 to move upward and reset under the action of the vertical spring 32, thereby pumping the hydraulic oil in the piston cylinder 44 back to the hydraulic cylinder 41 through the hydraulic pipe 43, and the pressure in the piston cylinder 44 will cause the piston block 45 and the extrusion block 46 to move and reset.

[0038] Embodiment 3: Based on embodiment 2, Figure 9-14As shown, a reinforcement mechanism is also included, which is arranged on the connecting rod 311. The reinforcement mechanism includes a net plate 51, a rubber net 52, a fixing frame 53 and a rubber ring 54. The lower part of the connecting rod 311 is connected to the net plate 51 by bolts, and the net plate 51 is located below the placement shell 2. The eight clamping rods 35 all pass through the net plate 51, and the bottom of the net plate 51 is fixedly connected to the rubber net 52. The eight clamping rods 35 all pass through the rubber net 52. The lower parts of the eight clamping rods 35 are connected to the fixing frames 53 by bolts. The eight fixing frames 53 are all located below the net plate 51, and the tops of the eight fixing frames 53 are fixedly connected to the rubber rings 54.

[0039] When the placement plate 31 drives the connecting rod 311 to move downward, the connecting rod 311 will drive the installation net plate 51 to move downward, and the movement of the installation net plate 51 will drive the rubber net 52 to move downward. When the clamping spring 36 drives the clamping rod 35 to move in the direction close to the placement plate 31, the clamping rod 35 will drive the fixing frame 53 to move in the direction close to the connecting rod 311, and the movement of the fixing frame 53 will drive the rubber ring 54 to move in the direction close to the connecting rod 311. The bottom of the rubber net 52 will contact the tops of the eight rubber rings 54. The rubber net 52 and the rubber ring 54 are both made of rubber material, which can increase the friction between the rubber net 52 and the rubber ring 54. In this way, the friction between the rubber net 52 and the rubber ring 54 is increased, so that the clamping rod 35 remains motionless after clamping the workpiece 21, so that the workpiece 21 can be more stably limited and fixed.

[0040] Embodiment 4: Based on the embodiment 3, Figure 1-Figure 13 As shown, it also includes a pressing mechanism, which is arranged on the clamping rod 35. The pressing mechanism includes a pressing rod 61, a pressing block 62, a limiting block 63, a displacement frame 64, a horizontal spring 65 and a limiting rod 66. The tops of the eight clamping rods 35 are slidably connected to the pressing rod 61, and the tops of the eight pressing rods 61 are connected to the pressing blocks 62 by bolts. Each of the clamping rods 35 is connected to two limiting blocks 63 by bolts. The two limiting blocks 63 form a group, and the displacement frame 64 is slidably connected between the two limiting blocks 63 of each group. A horizontal spring 65 is connected between each limiting block 63 and the displacement frame 64 by a hook. The inner wall of each displacement frame 64 is connected to a limiting rod 66 by bolts. A limiting groove 67 is opened on the upper part of each pressing rod 61, and the end of the limiting rod 66 away from the displacement frame 64 contacts the limiting groove 67.

[0041] At first, the limiting rod 66 contacts with the limiting groove 67, and the limiting rod 66 limits the pressing rod 61. When the clamping spring 36 drives the clamping rod 35 to move in the direction close to the placement plate 31, the clamping rod 35 will drive the pressing rod 61, the pressing block 62, the limiting block 63, the displacement frame 64, the horizontal spring 65 and the limiting rod 66 to move in the direction close to the workpiece 21. The displacement frame 64 will contact with the workpiece 21, and the workpiece 21 will squeeze the displacement frame 64 to move in the direction close to the placement shell 2. The horizontal spring 65 will be stretched, so that the displacement frame 64 limits and fixes the workpiece 21, and the limiting rod 66 will be out of contact with the pressing rod 61, so that the limiting rod 66 no longer limits the pressing rod 61. The staff will push the eight pressing blocks 62 to move downward, and the top edge of the workpiece 21 will contact the bottom of the eight pressing blocks 62. The movement of the pressing blocks 62 will drive the pressing rod 61 moves downward, and when the workpiece 21 is processed, the staff will take away the workpiece 21, the displacement frame 64 will be out of contact with the workpiece 21, and the horizontal spring 65 will reset. The reset of the horizontal spring 65 will drive the displacement frame 64 to move and reset, and the reset of the displacement frame 64 will drive the limit rod 66 to reset, and the limit rod 66 will contact the lower pressure rod 61 again, and then the staff will pull the lower pressure block 62 to move upward and reset. The reset of the lower pressure block 62 drives the lower pressure rod 61 to move upward and reset, and the limit rod 66 will contact the limit groove 67 again, and the limit rod 66 will limit the lower pressure rod 61 again. In this way, the displacement frame 64 is pushed by the horizontal spring 65 to further limit and fix the workpiece 21, and the top of the workpiece 21 is limited and fixed by the lower pressure block 62, so that the workpiece 21 is not easy to move up and down during the processing, so that the workpiece 21 can be limited and fixed more stably.

[0042] Embodiment 5: Based on Embodiment 4, Fig.14 As shown, a stabilizing mechanism is also included, which is arranged in a fixing frame 53. The stabilizing mechanism includes a friction ring 71, a horizontal displacement plate 72, a vertical displacement plate 73 and a small spring 74. A horizontal displacement plate 72 is slidably connected to each fixing frame 53, and each horizontal displacement plate 72 is provided with an inclined surface. A friction ring 71 is fixedly connected to each horizontal displacement plate 72, and each friction ring 71 contacts the lower part of the lower pressing block 62. A vertical displacement plate 73 is slidably connected to each fixing frame 53, and each vertical displacement plate 73 is provided with an inclined surface at the lower part. The vertical displacement plate 73 passes through the rubber ring 54, and the bottom of the vertical displacement plate 73 contacts the end of the horizontal displacement plate 72 away from the friction ring 71. A small spring 74 is connected between each vertical displacement plate 73 and the fixing frame 53 through a hook.

[0043] When the rubber ring 54 contacts the rubber net 52, the rubber net 52 will push the vertical displacement plate 73 to move downward, the small spring 74 will be compressed, and the vertical displacement plate 73 moving downward will apply horizontal pressure to the friction ring 71 through the horizontal displacement plate 72, thereby increasing the friction force between the friction ring 71 and the lower pressure rod 61, making it difficult for the lower pressure rod 61 and the lower pressure block 62 to move up and down during the machining of the workpiece 21, thereby being able to further and more stably limit and fix the workpiece 21. When the machining of the workpiece 21 is completed, the staff will pull the lower pressure block 62 to move upward and reset. The reset of the lower pressure block 62 will drive the lower pressure rod 61 to move upward and reset. The staff will take away the workpiece 21, the rubber ring 54 will disengage from the rubber net 52, the small spring 74 will reset, and the reset of the small spring 74 will drive the vertical displacement plate 73 to move upward and reset, so that the vertical displacement plate 73 no longer applies pressure to the horizontal displacement plate 72.
