Description

Technical Field

[0001] This utility model relates to a positioning fixture for automotive parts, belonging to the field of automotive parts processing. Background Technology

[0002] Automotive parts are the various units that make up a car and the products that serve the car. Most automotive parts are irregular in shape and angle. A small number of automotive parts can be used as components using stamping dies or cast iron molds. Most automotive parts require secondary processing to be assembled into a usable part, as shown in the attached diagram in the instruction manual. Figure 1 The automotive parts shown require welding of multiple automotive components simultaneously to reduce production steps and improve production efficiency.

[0003] Because automotive parts are polyhedrals with open tops, current clamps use a top-down extrusion method or two clamping blocks for holding. For automotive parts with open tops, large weight, high depth, and made of metal, the clamping is unstable. The clamps cannot make judgments when they are working or not, resulting in low automation.

[0004] Therefore, this utility model provides a positioning fixture for automotive parts with a polyhedral shape that is suitable for top openings and can be used for positioning and detection. Utility Model Content

[0005] In view of this, the purpose of this utility model is to provide a positioning fixture for automotive parts that is suitable for multi-faceted parts with open tops and can be used for positioning and detection.

[0006] This utility model is implemented as follows:

[0007] A positioning fixture for automotive parts consists of two symmetrically arranged positioning components. Each positioning component includes an automotive part, a fixed bracket, two fixed claws, and a positioning detector. The fixed bracket has fixed claws at both ends, and the ends of the fixed claws extend into the automotive part and contact the side wall of the automotive part. A positioning detector is installed on the fixed bracket between the two fixed claws.

[0008] As a further improvement, the fixing claw includes a support rod and a pressure block. One end of the support rod is screwed to the bottom surface of the first or last end of the fixing bracket, and the bottom end of the support rod is locked with the pressure block, which is in movable contact with the automotive parts.

[0009] As a further improvement, the fixing claw also includes a sound-silencing layer disposed between the pressure block and the end of the support rod.

[0010] As a further improvement, the positioning assembly also includes a robotic arm that controls the movement of the fixed support.

[0011] As a further improvement, the robotic arm includes a cylinder, a main arm, and a movable arm. The bottom end of the main arm is connected to the output end of the cylinder, so that the cylinder drives the main arm to rise or fall. The top end of the main arm is rotatably connected to the movable arm, and the free end of the movable arm is fixed to the middle part of the fixed bracket.

[0012] As a further improvement, the support rod includes a vertical part and a horizontal part, the vertical part and the horizontal part being perpendicular to each other, and a pressure block locking the free end of the horizontal part.

[0013] As a further improvement, the two fixing claws are parallel to each other, and the distance between the two fixing claws is greater than 15cm.

[0014] As a further improvement, the horizontal width of the horizontal portion is less than one-third of the vertical height of the vertical portion.

[0015] As a further improvement, the sound-absorbing layer is made of sponge material.

[0016] As a further improvement, the positioning detector is fixed between the positioning and the fixed bracket by a second support rod.

[0017] The beneficial effects of this utility model are:

[0018] ① This utility model uses symmetrically arranged fixing claws to extend into the automotive parts, contact the side wall of the automotive parts, and then adjust and fix them left and right. No matter how deep the automotive parts are, they can be inserted. Since the clamping is performed from the inside to the outside from the left and right, a positioning detector is set between the two fixing claws to prevent gaping.

[0019] ② The two fixing claws of this utility model are parallel to each other, and the distance between the two fixing claws is greater than 15cm. The farther the distance, the farther the car parts are supported, making it easier to stably clamp the car parts; the horizontal width of the horizontal part is less than one-third of the vertical height of the vertical part. With just a slight horizontal adjustment, it can directly touch the inner wall of the car parts, improving production efficiency. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0029] Reference Figures 1-6As shown, this embodiment provides a positioning fixture for an automotive part, which consists of two sets of positioning components symmetrically arranged. Each set of positioning components includes an automotive part 10, a fixed bracket 20, two fixed claws 30, and a positioning detector 40. The fixed bracket 20 has fixed claws 30 fixed at both ends. The ends of the fixed claws 30 extend into the automotive part 10 and contact the side wall of the automotive part 10. The positioning detector 40 is installed on the fixed bracket 20 between the two fixed claws 30.

[0030] This utility model uses symmetrically arranged fixing claws 30 to extend into the automotive part 10, contact the side wall of the automotive part 10, and then adjust and fix it from left to right. It can penetrate deeply no matter how deep the automotive part is. Since it uses left and right clamping from the inside to the outside, in order to prevent gaping, a positioning detector 40 is set between the two fixing claws 30. The positioning detector 40 mentioned here includes, but is not limited to, an infrared sensor, as long as it can detect the automotive part.

[0031] The fixing claw 30 includes a support rod 301 and a pressure block 302. One end of the support rod 301 is screwed to the bottom surface of the first or second end of the fixing bracket 20, and the pressure block 302 is locked to the bottom end of the support rod 301. The pressure block 302 is in movable contact with the automotive part 10. Using the support rod 301 as a connecting member can extend the depth of the pressure block 302 inside the automotive part 10, improving practicality.

[0032] Furthermore, the support rod 301 includes a vertical part 311 and a horizontal part 312, which are perpendicular to each other. The free end of the horizontal part 312 is locked with a pressure block 302, and a pressure block 302 is also installed on the side of the vertical part 311. After the pressure block 302 is inserted into the interior of the automotive part 10, it can directly touch the inner wall of the automotive part with only a slight horizontal adjustment, thereby improving production efficiency.

[0033] Furthermore, the positioning assembly also includes a robotic arm 50 for controlling the movement of the fixed support 20. The robotic arm 50 includes a cylinder 501, a main arm 502, and a movable arm 503. The bottom end of the main arm 502 is connected to the output end of the cylinder 501, causing the cylinder 501 to drive the main arm 502 to rise or fall. The movable arm 503 is rotatably connected to the top end of the main arm 502, and the free end of the movable arm 503 is fixed to the middle portion of the fixed support 20. This enables the robotic arm 50 to drive the fixed support 20 to rotate upwards or downwards.

[0034] In one specific embodiment, the two fixing claws 30 are parallel to each other, and the distance between the two fixing claws 30 is greater than 15cm. The greater the distance, the greater the distance of the supported car parts, making it easier to stably clamp the car parts.

[0035] In one specific embodiment, the horizontal width of the horizontal part 312 is less than one-third of the vertical height of the vertical part 311. With just a slight horizontal adjustment, it can directly touch the inner wall of the automotive parts, thereby improving production efficiency.

[0036] In one specific embodiment, the positioning detector 40 is fixed between the second support rod 60 and the fixed bracket 20.

[0037] In some embodiments, the end face of the pressure block 302 away from the support rod 301 is a smooth surface, which will not damage the paint of the automotive parts.

[0038] In some embodiments, the end face of the pressure block 302 away from the support rod 301 is a rough surface. The roughness of the end face increases friction and resistance, making it less likely to slide down.

[0039] In other embodiments, the fixing claw 30 further includes a sound-silencing layer 302 disposed between the pressure block 302 and the end of the support rod 301 to reduce the noise generated when the fixing claw 30 vibrates.

[0040] In one specific embodiment, the sound-absorbing layer 302 is made of sponge material, which is common, easy to process, and easy to install and replace after damage.

[0041] In one specific embodiment, the thickness of the sound-silencing layer 302 is 0.2-1.5cm to avoid excessive thickness, which would cause the edges of the sound-silencing layer 302 to shed, thus improving the stability of the device.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
