Description

Technical Field

[0001] This utility model belongs to the field of positioning mechanisms, specifically, it relates to a positioning mechanism for processing automotive parts. Background Technology

[0002] As the foundation of the automotive industry, auto parts are a necessary factor to support the industry's continued healthy development. There are many types of auto parts, and when tubular auto parts are being processed, positioning mechanisms are needed to position them in the appropriate locations.

[0003] Chinese Patent No. CN220575697U discloses a positioning mechanism for processing automotive parts. Paragraph 31 of the specification discloses that a tubular automotive part is placed on a limiting plate and positioned between four clamping assemblies. The control motor drives the first gear to rotate, and the rotating first gear drives the rotating tube to rotate in the bearing through the second gear. The rotating tube drives the third gear to rotate, and the rotating third gear drives four fourth gears to rotate. The four rotating fourth gears all drive the first threaded cylinder to rotate in the bearing seat. The four rotating first threaded cylinders all drive the four clamping assemblies to move closer or further apart through the second threaded cylinder and the threaded rod.

[0004] However, the positioning mechanism for the aforementioned automotive parts processing directly squeezes and clamps the outer side of the tubular automotive parts through the clamping components. Since the inner wall of the tubular automotive parts lacks support, it is easy to squeeze and deform the tubular automotive parts.

[0005] In view of this, this utility model is proposed. Utility Model Content

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a positioning mechanism for the processing of automotive parts.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0009] Optionally, the upper side of the base is provided with a first T-shaped channel, and the slide bar is a T-shaped strip structure, which slides within the first T-shaped channel.

[0010] Optionally, the first drive mechanism includes a first servo motor disposed on the side of the base, a bidirectional threaded rod disposed at the output end of the first servo motor and threaded with the two slide bars, the two ends of the bidirectional threaded rod having opposite thread directions, the two ends of the bidirectional threaded rod respectively threaded with the two slide bars, a connecting plate disposed on the upper side of the slide bar, and a plurality of first spring dampers disposed between the connecting plate and the support plate.

[0011] Optionally, the upper side of the slider is provided with a second T-shaped groove, and the slider is a T-shaped block structure, which slides within the second T-shaped groove.

[0012] Optionally, the second drive mechanism includes a second servo motor located on the side of the base, a polygonal drive shaft located at the output end of the second servo motor, and an externally threaded cylinder rotatably fitted on the inner wall of the second T-shaped channel and threadedly fitted with the slider. The externally threaded cylinder is slidably sleeved on the polygonal drive shaft, and the threads of the two externally threaded cylinders are opposite in direction. One side of the slider is provided with a circular hole corresponding to the polygonal drive shaft. A fixing plate is provided on the upper side of the slider, and a plurality of second spring dampers are provided between the fixing plate and the clamping plate.

[0013] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0014] The first driving mechanism drives two sliders to slide, adjusting the distance between the two support plates to facilitate the positioning of different tubular parts. The tubular part is placed on the two support plates. The first driving mechanism drives the two sliders to slide, and the support plates elastically support the inner wall of the tubular part.

Detailed Implementation

[0023] The present invention will now be described in further detail with reference to the accompanying drawings.

[0024] Please see Figure 1-3 As shown, this embodiment provides a positioning mechanism for processing automotive parts, including a base 1, two slide bars 101 that slide towards each other on the upper side of the base 1, a first driving mechanism 102 for driving the two slide bars 101 to slide towards each other on one side of the base 1, a support plate 103 that slides elastically on the upper side of the slide bars 101, a slider 104 that slides on the upper side of the slide bars 101, a clamping plate 105 that slides elastically on the upper side of the slider 104, and a second driving mechanism 106 for driving the two sliders 104 to slide towards each other on one side of the base 1.

[0025] The first driving mechanism 102 drives the two slide bars 101 to slide, adjusting the distance between the two support plates 103 to facilitate the positioning of different tubular parts. The tubular part is fitted onto the two support plates 103. The first driving mechanism 102 drives the two slide bars 101 to slide, and the support plates 103 elastically support the inner wall of the tubular part. At the same time, the second driving mechanism 106 drives the slider 104 to slide, so that the clamping plate 105 elastically squeezes and positions the outer wall of the tubular part, thereby simultaneously squeezing the inner and outer walls of the tubular part, which helps to improve the stability of the positioning of the tubular part and reduce the probability of the tubular part being squeezed and deformed.

[0026] For elastic support of the inner wall of tubular parts, please refer to Figure 1-2As shown, the base 1 in this embodiment has a first T-shaped channel 107 on its upper side. The slide bar 101 has a T-shaped strip structure. The slide bar 101 slides in the first T-shaped channel 107, which facilitates the sliding of the slide bar 101 through the first T-shaped channel 107 and improves the stability of the slide bar 101. The first drive mechanism 102 includes a first servo motor 1021 located on the side of the base 1 and a bidirectional threaded rod 1022 located at the output end of the first servo motor 1021 and threaded with the two slide bars 101. The two ends of the bidirectional threaded rod 1022 have opposite thread directions. The two ends of the bidirectional threaded rod 1022 are threaded with the two slide bars 101 respectively. A connecting plate 108 is provided on the upper side of the slide bar 101. A plurality of first spring dampers 109 are provided between the connecting plate 108 and the support plate 103, which facilitates the first servo motor 1021 to drive the bidirectional threaded rod 1022 to drive the two slide bars 101 to slide. The support plate 103 elastically supports the inner wall of the tubular part through the first spring dampers 109.

[0027] For elastic compression positioning of the outer wall of the tubular part, please refer to Figure 1-3 As shown, in this embodiment, the upper side of the slider 101 is provided with a second T-shaped groove 110, and the slider 104 has a T-shaped block structure. The slider 104 slides within the second T-shaped groove 110, which facilitates guiding the slider 104 to slide through the second T-shaped groove 110 and improves the stability of the slider 104's sliding. The second drive mechanism 106 includes a second servo motor 1061 located on the side of the base 1, a polygonal drive shaft 1062 located at the output end of the second servo motor 1061, and an external threaded cylinder 1063 rotatably fitted on the inner wall of the second T-shaped groove 110 and threadedly engaged with the slider 104. The inner wall of 063 has a polygonal hole structure. The external threaded cylinder 1063 is slidably sleeved on the polygonal drive shaft 1062. The two external threaded cylinders 1063 have opposite thread directions. The slider 101 has a circular hole 113 on one side corresponding to the polygonal drive shaft 1062. The upper side of the slider 104 is provided with a fixing plate 111. Multiple second spring dampers 112 are provided between the fixing plate 111 and the clamping plate 105. The second servo motor 1061 drives the polygonal drive shaft 1062 to drive the slider 104 to slide through the external threaded cylinder 1063, so that the clamping plate 105 elastically squeezes the outer wall of the positioning tubular part through the second spring dampers 112.

[0028] Working principle: The first servo motor 1021 drives the bidirectional threaded rod 1022 to slide the two slide bars 101, adjusting the distance between the two support plates 103 to accommodate different tubular parts. The tubular part is then placed on the two support plates 103. The first servo motor 1021 drives the bidirectional threaded rod 1022 to slide the two slide bars 101. The support plates 103 elastically support the inner wall of the tubular part through the first spring damper 109. At the same time, the second servo motor 1061 drives the polygonal transmission shaft 1062 to slide the slider 104 through the external threaded cylinder 1063. This causes the clamping plate 105 to elastically compress the outer wall of the tubular part through the second spring damper 112, thereby simultaneously compressing both the inner and outer walls of the tubular part. This improves the stability of the tubular part's positioning and reduces the probability of the tubular part being deformed by compression.
