Description

Technical Field

[0001] This utility model relates to the field of mechanical automation technology, specifically a lightweight cam roller turntable. Background Technology

[0002] Mechanical automation refers to the process by which machines or devices operate or are controlled automatically according to predetermined programs or instructions without human intervention. Mechanical automation is the process by which machines or devices achieve automated control through mechanical means. With the current high labor costs, automated equipment can replace most simple and repetitive labor. For some complex working conditions that have extremely high equipment requirements, more complex and precise equipment is needed, and the corresponding requirements for equipment accessories will also increase. When automating the processing of some mechanical workpieces, for some functional parts that need to move, cam roller turntables are needed to provide the workpiece with rotation, indexing, or oscillation with reduction ratios.

[0003] However, existing cam roller turntables are large in size, have high load capacity, and poor precision. They are mainly designed for high-load applications and do not consider lightweight applications. Therefore, this invention provides a lightweight cam roller turntable. Utility Model Content

[0004] The purpose of this invention is to provide a lightweight cam roller turntable, which solves the problems mentioned in the background art.

[0005] This application provides a lightweight cam roller rotary table, including a housing, a roller indexing plate, a camshaft, and an integral crossed roller bearing. The roller indexing plate, camshaft, and integral crossed roller bearing are all installed inside the housing. The camshaft matches the rollers of the roller indexing plate. The roller indexing plate passes through the integral crossed roller bearing, and the roller indexing plate is connected to the housing via the integral crossed roller bearing. An input interface component is fixedly installed on one side of the housing. One end of the camshaft is located inside the input interface component, and both ends of the camshaft are provided with eccentric adjustment mechanisms.

[0006] By adopting the above technical solution, the integral crossed roller bearing can be used for load bearing and to ensure the runout and coaxiality of the roller indexing plate end face. The camshaft and roller indexing plate can transmit the prime mover and provide the reduction ratio. After assembly and debugging, appropriate preload can ensure the axial accuracy of the transmission. Two eccentric adjustment mechanisms can adjust the camshaft so that the camshaft and roller indexing plate have a unique and suitable position during operation. Moreover, the eccentric adjustment mechanism adopts a pre-embedded method, which makes the product smaller and improves the energy density.

[0007] Optionally, the camshaft has a socket at one end inside the input interface component, and the socket has a slot.

[0008] By adopting the above technical solution, the functional components that provide power can be directly inserted into the socket and slot and locked to the camshaft without the need for a coupling, thus reducing the installation space.

[0009] Optionally, the camshaft is connected to the housing via a rolling bearing.

[0010] By adopting the above technical solution, the stability of camshaft rotation is ensured.

[0011] Optionally, the length, width, and height of the housing are 200mm, 160mm, and 90mm, respectively.

[0012] By adopting the above technical solution, the lightweight design of the cam roller turntable is ensured.

[0013] Optionally, the housing has four mounting holes.

[0014] By adopting the above technical solution, it is convenient to install the cam roller turntable on the worktable.

[0015] Optionally, the roller indexing plate has a plurality of fixing holes, and the plurality of fixing holes are arranged in a circular array with the axial direction of the roller indexing plate as the center.

[0016] By adopting the above technical solution, it is convenient to fix the workpiece on the roller indexing plate.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] 1. The technical solution of this application uses an integral crossed roller bearing to bear weight and ensure the runout and coaxiality of the roller indexing plate end face. The camshaft and roller indexing plate can transmit the prime mover and provide a reduction ratio. After assembly and debugging, appropriate preload can ensure the axial accuracy of the transmission. The camshaft can be adjusted by two eccentric adjustment mechanisms so that the camshaft and roller indexing plate have a unique and suitable position during operation. The eccentric adjustment mechanism adopts a pre-embedded method, which makes the product smaller and improves the energy density.

[0019] 2. The cam roller turntable in this application is lightweight and has a square shape, which makes it easy to install. Moreover, the power functional components can be directly locked to the camshaft without the need for a coupling, thus reducing the installation space. Attached Figure Description

[0026] Please see Figure 1-2 This utility model provides a lightweight cam roller turntable, including a housing 1, a roller indexing plate 2, a camshaft 7, and an integral cross roller bearing 9. The roller indexing plate 2, the camshaft 7, and the integral cross roller bearing 9 are all installed inside the housing 1. The camshaft 7 matches the rollers of the roller indexing plate 2. The roller indexing plate 2 passes through the integral cross roller bearing 9, and the roller indexing plate 2 is connected to the housing 1 through the integral cross roller bearing 9. An input interface component 3 is fixedly installed on one side of the housing 1. One end of the camshaft 7 is located inside the input interface component 3, and both ends of the camshaft 7 are provided with an eccentric adjustment mechanism 8.

[0027] In this technical solution, the integral crossed roller bearing 9 can be used to bear weight and ensure the runout and coaxiality of the roller indexing plate 2 end face. The camshaft 7 and the roller indexing plate 2 can transmit the prime mover and provide the reduction ratio. After assembly and debugging, appropriate preload can ensure the axial accuracy of the transmission. The camshaft 7 can be adjusted by two eccentric adjustment mechanisms 8 so that the camshaft 7 and the roller indexing plate 2 have a unique and suitable position during operation. The eccentric adjustment mechanism 8 adopts a pre-embedded method, which makes the product smaller and improves the energy density.

[0028] In some technical solutions, such as Figure 2-3 As shown, the camshaft 7 has a socket 4 at one end inside the input interface 3, and a slot 10 is provided on the socket 4.

[0029] In use, the power-providing functional components can be easily inserted directly into and locked to the camshaft 7 through the insertion hole 4 and the slot 10, without the need for a coupling, thus reducing the installation space.

[0030] In some technical solutions, such as Figure 2 As shown, the camshaft 7 is connected to the housing 1 by a rolling bearing.

[0031] During use, ensure the stability of the camshaft 7 rotation.

[0032] In some technical solutions, such as Figure 1-2 As shown, the length, width and height of the shell 1 are 200mm, 160mm and 90mm respectively.

[0033] In use, the smaller size of the housing 1 ensures the lightweight design of the cam roller turntable.

[0034] In some technical solutions, such as Figure 1-2 As shown, the housing 1 has four mounting holes 5.

[0035] In use, the cam roller turntable can be easily installed on the worktable through the mounting hole 5.

[0036] In some technical solutions, such as Figure 1-2 As shown, the roller indexing plate 2 has several fixing holes 6, and the fixing holes 6 are arranged in a ring array with the axial direction of the roller indexing plate 2 as the center.

[0037] In use, the workpiece can be easily fixed on the roller indexing plate 2 through multiple fixing holes 6.

[0038] Working principle: During use, the camshaft 7 is first adjusted by two eccentric adjustment mechanisms 8 to ensure that the camshaft 7 and the roller indexing plate 2 have a unique and suitable position during operation. Then, the power function component is directly inserted into the socket 4 and the slot 10 and locked to the camshaft 7. The camshaft 7 transmits power to the roller indexing plate 2. Since the roller indexing plate 2 is fixed on the integral crossed roller bearing 9, the rotational motion of the roller indexing plate 2 can be transmitted to the integral crossed roller bearing 9. This ensures that the input rotational accuracy is almost not lost. While ensuring rotational accuracy, end face runout and coaxiality, it provides load-bearing capacity and increases the reduction ratio of the input force.

[0039] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
