Description

Technical Field

[0001] This utility model relates to the field of automobile processing and production, and more specifically, to a positioning device. Background Technology

[0002] In automotive manufacturing production lines (such as assembly lines), pallets are used to transport components to be processed along with conveyor chains. When the pallet reaches the target location, a positioning pin is used to fix the pallet in place to facilitate the processing of the components on the pallet.

[0003] A positioning device is typically used to install the positioning pin, which is then driven to insert into the positioning hole, thus securing the entire tray. Utility Model Content

[0004] In view of this, the present invention proposes a positioning device.

[0005] A positioning device according to an embodiment of the present invention includes:

[0006] A base, wherein the base is installed horizontally;

[0007] A drive mechanism, fixed on the base, includes an output shaft that is arranged parallel to the base;

[0008] A first pushing mechanism is connected to the output shaft;

[0009] The second pushing mechanism is connected to the first pushing mechanism and includes a first connecting plate that can move vertically; a positioning pin is vertically disposed on the first connecting plate.

[0010] Furthermore, the base is horizontally provided with a first track, and the first pushing mechanism includes a second connecting plate that is slidably disposed on the first track, the second connecting plate being connected to the output shaft of the driving mechanism.

[0011] Furthermore, the first pushing mechanism also includes a third connecting plate, one end of which is connected to the output shaft of the driving mechanism, and the other end of which is connected to the second connecting plate.

[0012] Furthermore, a fixed support is vertically arranged on the base, and a second track is provided on the end face of the fixed support. The second pushing mechanism includes a fourth connecting plate that is slidably arranged on the second track, and the fourth connecting plate is connected to the first connecting plate.

[0013] Furthermore, the first connecting plate and the second connecting plate are connected by a connecting rod, the connecting rod having a first end and a second end opposite to each other, the first end of the connecting rod being connected to the first connecting plate, and the second end of the connecting rod being connected to the second connecting plate.

[0014] Furthermore, the fixed support includes a first end face and a second end face, the second track is mounted on the first end face, and the drive mechanism is disposed on one side of the second end face.

[0015] Furthermore, the first track includes a first guide rail and a second guide rail arranged in parallel, and / or the second track includes a third guide rail and a fourth guide rail arranged in parallel.

[0016] Furthermore, the first and second guide rails are T-shaped guide rails, and / or the third and fourth guide rails are T-shaped guide rails.

[0017] Furthermore, the positioning device is horizontally mounted on the external chain bed via the base.

[0018] According to one embodiment of the present invention, a positioning device includes a base, a drive mechanism, a first pushing mechanism, and a second pushing mechanism. The drive mechanism, the first pushing mechanism, and the second pushing mechanism are mounted on a horizontally arranged base. The first pushing mechanism is connected to the drive mechanism and the second pushing mechanism. The second pushing mechanism is also provided with a first connecting plate that can move vertically and is used to install a positioning pin. In this way, the drive mechanism drives the first pushing mechanism horizontally, and then the first pushing mechanism drives the second pushing mechanism to move vertically, thereby driving the positioning pin provided on the second pushing mechanism to move up and down. This realizes the function of inserting the positioning pin into the positioning hole of the tray above the device or leaving the positioning hole, so as to achieve positioning or free movement.

[0019] As can be seen, the positioning device in this embodiment is installed horizontally, which has little impact on the operating space below the chain bed; in addition, the force direction of the guide rail slider of this device is positive downward pressure, which can ensure the service life of the guide rail and reduce maintenance and warranty costs.

[0028] 12 Second connecting plate 13 Third connecting plate 14 Fourth connecting plate

[0029] 21 connecting rod, 31 first support, 50 cylinder

[0030] 60 guide rail, 70 sliding end plate, 100 positioning pin Detailed Implementation

[0031] To make the objectives, technical solutions and advantages of this utility model clearer, the following embodiments will be used to further describe this utility model in detail.

[0032] Figure 1 The existing positioning device structure includes a cylinder 50 mounted on a chain bed, a guide rail 60 parallel to the cylinder's output rod, and a sliding end plate 70 slidably mounted on the guide rail 60 via a slider. A positioning pin 100 for insertion into a positioning hole is vertically mounted on the sliding end plate. The sliding end plate 70 is connected to the cylinder's output rod so that it slides along the guide rail 60 under the action of the output rod, causing the positioning pin 100 mounted thereon to move up and down, thereby inserting into or disengaging from the positioning hole at the bottom of the tray. Figure 1 The existing solutions have two main drawbacks: first, the overall vertical installation occupies the operating space below the chain bed, causing interference; second, the force on the guide rail slider is not downward but rather subjected to torsional load, which reduces the service life of the guide rail and increases maintenance costs. Therefore, this invention provides a new positioning device that can at least solve one or more of the above-mentioned technical problems.

[0033] Figure 2 This is a schematic diagram of the positioning device according to an embodiment of the present invention;

[0034] like Figure 2As shown, the positioning device includes a base 1, a drive mechanism 2, a first push mechanism, and a second push mechanism. The base 1 is horizontally installed, and the drive mechanism 2 is fixed on the base 1 and includes an output shaft that is parallel to the base 1. The first push mechanism is connected to the output shaft. The second push mechanism is connected to the first push mechanism and includes a first connecting plate 11 that can move vertically. A positioning pin 100 is vertically arranged on the first connecting plate 11.

[0035] The positioning device based on this embodiment is horizontally arranged. A drive mechanism 2 is provided to push the first pushing mechanism horizontally. A second pushing mechanism connected to the first pushing mechanism is provided, and the second pushing mechanism has a vertically movable first connecting plate 11. Under the extension and retraction of the output rod of the drive mechanism 2, the first connecting plate 11 is moved vertically, thereby inserting or removing the positioning pin 100 into the positioning hole. Preferably, the drive mechanism 2 is a cylinder 50. The first pushing mechanism is connected to the output rod of the cylinder 50 and can move horizontally under the action of the output rod of the cylinder 50.

[0036] Furthermore, the base 1 is horizontally provided with a first track 3, and the first pushing mechanism includes a second connecting plate 12 slidably disposed on the first track 3, the second connecting plate 12 being connected to the output shaft of the driving mechanism 2. In this embodiment, by providing a second connecting plate 12 that can move along the first track 3 and connecting the second connecting plate 12 to the output shaft of the driving mechanism 2, the second connecting plate 12 can move horizontally under the action of the output shaft of the driving mechanism 2.

[0037] Preferably, the second connecting plate 12 can be connected to the first slider that is slidably mounted on the first track 3 via bolts or other fasteners. As can be seen, in this embodiment, the slider of the first guide rail 60 experiences downward pressure, thus ensuring the service life of the guide rail 60 and reducing maintenance and warranty costs.

[0038] Based on the above embodiments, the first pushing mechanism further includes a third connecting plate 13. One end of the third connecting plate 13 is connected to the output shaft of the drive mechanism 2, and the other end of the third connecting plate 13 is connected to the second connecting plate 12. Specifically, the second connecting plate 12 is a horizontally arranged end plate with a certain thickness, and it has an opening corresponding to the position of the output shaft. The third connecting plate 13 is set as a vertical end plate, which is connected to the end of the output shaft by fasteners such as bolts. In this way, under the action of the output shaft of the drive mechanism 2, the third connecting plate 13 abuts against the end of the second connecting plate 12 behind the opening, thereby pushing the second connecting plate 12, making the overall force more balanced, the device more stable, and the service life longer.

[0039] Furthermore, a fixed support 5 is vertically arranged on the base 1, and a second track 7 is provided on the end face of the fixed support 5. The second pushing mechanism includes a fourth connecting plate 14 slidably arranged on the second track 7, and a first connecting plate 11 is connected to the fourth connecting plate 14. Specifically, the second track 7 is parallel to the fixed support 5 and is fixed to one end face of the vertically arranged fixed support 5 by bolts or other fasteners. The fourth connecting plate 14 is connected to the second slider slidably arranged on the second track 7 by bolts or other fasteners. The fourth connecting plate 14 is also connected to the first connecting plate 11. In this way, when the fourth connecting plate 14 slides up and down along the second track 7, it will drive the positioning pin 100 on the first connecting plate 11 to move up and down.

[0040] Based on the above embodiments, the fixed support 5 further includes a first end face and a second end face, the second track 7 is installed on the first end face, and the drive mechanism 2 is disposed on one side of the second end face. This embodiment makes the overall structure more compact and makes full use of the space of the base 1. Preferably, first brackets 31 are installed on both sides of the second end face of the base 1 for reinforcement.

[0041] Based on the above embodiments, the first connecting plate 11 and the second connecting plate 12 are further connected by a connecting rod 21. The connecting rod 21 includes a first connecting rod end and a second connecting rod end opposite to each other. The first connecting rod end is connected to the first connecting plate 11, and the second connecting rod end is connected to the second connecting plate 12.

[0042] Specifically, an extension plate parallel to the first track 3 is provided on the side of the second connecting plate 12 near the fixing plate of the positioning pin 100. The first end of the connecting rod 21 is fixed to the extension plate by bolts or other fasteners. A second bracket is installed in the right-angle space formed between the fixing plate of the positioning pin 100 and the fourth connecting plate 14. The second end of the connecting rod is installed on the second bracket by bolts or other fasteners. In this embodiment, by providing the connecting rod 21 between the first connecting plate 11 and the second connecting plate 12, the first connecting plate 11 can move up and down as the second connecting plate 12 slides on the first track 3. It can also be seen that, in the prior art, the vertical displacement generated by the positioning pin 100 is the extension and retraction displacement of the output rod of the cylinder 50. However, in this embodiment of the present invention, the output rod of the cylinder 50 is driven horizontally. Combined with the up and down action of the connecting rod 21, its stroke distance is greater. Therefore, for the same specification requirements, the total height of the device is reduced compared to the prior art, thereby saving cost and space.

[0043] Based on the above embodiments, further, the first track 3 includes a first guide rail and a second guide rail arranged in parallel, and / or the second track 7 includes a third guide rail and a fourth guide rail arranged in parallel. This disperses and balances the force, making it more stable.

[0044] Furthermore, the first and second guide rails are T-shaped guide rails, and / or the third and fourth guide rails are T-shaped guide rails.

[0045] Furthermore, the positioning device is horizontally mounted on the external chain bed via the base 1. Based on this embodiment, the positioning device can be used on the chain bed of a production line to position and fix the pallets on the chain bed without consuming excessive vertical space, thus avoiding interference with equipment such as trolleys below the chain bed.

[0046] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
