Description

Technical Field

[0001] This utility model relates to the field of rack and pinion installation technology, specifically a rack and pinion adapter for a pneumatic wrench. Background Technology

[0002] A rack is a mechanical component with a toothed structure, usually used in conjunction with gears to convert rotary motion into linear motion (or vice versa). Due to its simple structure, high load-bearing capacity, and high transmission accuracy, racks have a wide range of applications in many fields.

[0003] Generally, a rack is connected to a telescopic cylinder, which serves as the power source to drive the rack to repeatedly perform linear motion. However, the rack can usually only be coaxially connected to the telescopic cylinder. Due to the different spaces in various devices, the installation position of the telescopic cylinder may not be able to match the position of the rack. In view of this situation, the present invention proposes a novel solution. Utility Model Content

[0004] The purpose of this invention is to provide a rack and pinion adapter for pneumatic wrenches to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rack and pinion adapter for a pneumatic wrench, comprising:

[0006] Adapter assembly, rack and pinion, and pneumatic wrench gloves;

[0007] The adapter assembly includes a first connecting unit and a second connecting unit. The first connecting unit is connected to the rack, and the second connecting unit is connected to the telescopic end of the cylinder. Both the first connecting unit and the second connecting unit can rotate to make the rack and the cylinder coaxial. The cylinder can drive the rack to translate through the adapter assembly.

[0008] Further, the adapter assembly includes two side plates, and connecting unit one and connecting unit two are respectively installed between the two ends of the two side plates. Connecting unit one and connecting unit two respectively include rotating shaft one and rotating shaft two, which are rotatably installed between the two side plates.

[0009] Further, the first surface of the rotating shaft is provided with a snap-fit ​​connector to connect and fix it to one end of the rack, and the second surface of the rotating shaft is provided with a screw connector to connect and fix it to the telescopic end of the cylinder.

[0010] Further, for this scheme, a gear 1 is fixed at one end of both the first and second rotating shafts, and two gears 2 are rotatably mounted on one side of one of the side plates. The two gears 2 are respectively meshed with the corresponding gear 1. Two limiting members are provided on the side plate for positioning the two gears 2.

[0011] Further, the side plate of the corresponding limiting component has an internal hexagonal hole, and a through hole is provided in the middle of the internal hexagonal hole to penetrate the side plate. A shaft is rotatably installed at the through hole, and the shaft is fixed coaxially with the gear. A hexagonal block is provided at the internal hexagonal hole and fits onto the surface of the shaft. The hexagonal block matches the internal hexagonal hole. The end of the shaft is threaded, and a positioning nut for limiting the hexagonal block is screwed into the thread.

[0012] Furthermore, the shaft has a card on the surface of the internal hexagonal hole, and the inner wall of the hexagonal block has a slot that matches the card, which engages with the card.

[0013] Furthermore, the rack is fitted with a pneumatic wrench sleeve at the end away from the snap-fit ​​connector, and the pneumatic wrench sleeve has a through hole in the middle that matches the output end of the pneumatic wrench.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] This pneumatic wrench rack and pinion adapter allows the rack and cylinder to be coaxial through the connecting unit one and connecting unit two of the adapter assembly. However, the cylinder can still drive the rack to move through the adapter assembly, which increases the flexibility and adaptability of the device. It can be used normally in situations where space is limited or the direction of movement needs to be changed, thus broadening the application range of pneumatic wrenches.

[0016] Meanwhile, after adjusting the position of the rack, the hexagonal block is pushed into the internal hexagonal hole, and the position can be kept stable without the aid of special tools. At the same time, the shaft and the hexagonal block are positioned by the cooperation of the card and the slot, which further ensures the position stability of the shaft, thereby realizing the quick fixation of the rack position, which is convenient for quick adjustment and fixation of the rack position in actual use.

[0024] like Figure 1 As shown, this utility model provides a technical solution: a rack and pinion adapter for a pneumatic wrench, comprising:

[0025] Adapter assembly, rack 5, and pneumatic wrench glove 7;

[0026] The adapter assembly includes a first connecting unit and a second connecting unit. The first connecting unit is connected to the rack 5, and the second connecting unit is connected to the telescopic end of the cylinder. Both the first connecting unit and the second connecting unit can rotate to make the rack 5 coaxial with the cylinder. The cylinder can drive the rack 5 to translate through the adapter assembly.

[0027] Further, the adapter assembly includes two side plates 1, and connecting unit one and connecting unit two are respectively installed between the two ends of the two side plates 1. The connecting unit one and connecting unit two respectively include rotating shaft one 2 and rotating shaft two 3, which are rotatably installed between the two side plates 1.

[0028] like Figure 2 and Figure 3As shown, further regarding this solution, the surface of the rotating shaft 2 is provided with a snap-fit ​​connector 6 to connect and fix one end of the rack 5, and the surface of the rotating shaft 3 is provided with a screw connector 4 to connect and fix the telescopic end of the cylinder. By connecting the rack 5 and the telescopic cylinder with conventional connectors, costs can be reduced and the connection process can be simplified.

[0029] like Figure 3 and Figure 4 As shown, further regarding this scheme, gear 9 is fixed to one end of both shaft 1 2 and shaft 2 3. Two gears 2 10 are rotatably mounted on one side of one of the side plates 1, and the two gears 2 10 are respectively meshed with the corresponding gear 1 9. Two limiting members 11 are provided on the side plate 1 for positioning the two gears 2 10. An internal hexagonal hole 12 is provided on the side plate 1 corresponding to the limiting member 11. A through hole is provided in the middle of the internal hexagonal hole 12, penetrating the side plate 1. A gear is rotatably mounted at the through hole. Shaft 111 is coaxially fixed with gear 2 10. A hexagonal block 114 is provided at the internal hexagonal hole 12, which fits onto the surface of shaft 111. The hexagonal block 114 matches the internal hexagonal hole 12. The end of shaft 111 is threaded, and a positioning nut 112 for limiting the hexagonal block 114 is screwed into the thread. A clip 115 is provided on the surface of shaft 111 at the internal hexagonal hole 12. A groove 11 is formed on the inner wall of hexagonal block 114 to fit the clip 115. 3. The slot 113 engages with the card 115. After the rack 5 is installed, the screw connector 4 of the device is screwed onto the threaded post 8 at the telescopic end of the telescopic cylinder, thus connecting the rack 5 to the telescopic cylinder via the adapter. After connection, since the cylinder needs to move the rack 5 horizontally, and both rotating shaft 2 and rotating shaft 3 are rotating parts, after determining the position of the rack 5, it is necessary to fix rotating shaft 2 and rotating shaft 3. During the adjustment of the position of the rack 5... Both the hexagonal block 114 and the positioning nut 112 are installed and adjusted. After installation, the hexagonal block 114 is pushed into the internal hexagonal hole 12. Since the internal hexagonal hole 12 and the hexagonal block 114 are not circular, the hexagonal block 114 remains stable after being pushed in. The shaft 111 and the hexagonal block 114 are positioned by the cooperation of the clip 115 and the slot 113. Therefore, the position of the shaft 111 remains stable and cannot rotate. Thus, after fixing, the position of the rack 5 is stable.

[0030] Further, a pneumatic wrench 7 is fitted onto the end of the rack 5 furthest from the clamp 6. The perforation in the middle of the pneumatic wrench 7 is adapted to the output end of the pneumatic wrench, thus realizing the linkage between the translational movement of the rack 5 and the pneumatic wrench, and completing the operation of tightening or loosening bolts and other objects.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
