AI Technical Summary
Traditional presses use sliding guides, which have problems such as high friction resistance, rapid wear, and high requirements for the manufacturing process of the guide surface.
An eight-sided needle roller guide device is used, including a machine body, a slider, a fixed needle roller guide seat, a needle roller bearing and an adjustable needle roller guide seat. By machining the contact surface of the fixed needle roller guide seat on the outside of the machine body and using the adjustable needle roller guide seat to adjust the position of the slider, friction is reduced and the guiding accuracy is improved.
The friction between the guide rail and the slider is reduced, the guiding accuracy of the guide rail is improved, and the requirements for the manufacturing process of the guide rail surface are reduced.

Abstract
Description
Technical Field
[0001] The utility model relates to a needle roller guide rail device for a press machine, in particular to an eight-sided needle roller guide rail device. Background Art
[0002] With the continuous advancement of technology, companies are placing increasingly higher demands on product quality, and consequently, on all aspects of presses. Traditional presses utilize sliding guides. While these guides are simple in structure and offer good rigidity, they suffer from high friction resistance, resulting in rapid wear with continuous operation, and they also place high demands on the manufacturing process for the guide surface. This patent effectively overcomes these shortcomings, reducing friction between the guide rail and the slider, improving guide rail guidance accuracy, and lowering the requirements for the guide surface manufacturing process. Utility Model Content
[0003] The purpose of the utility model is to provide an octagonal needle roller guide rail device with a simple structure, easy processing, convenient adjustment and improved processing accuracy, so as to solve the problems in the prior art.
[0004] The technical solution of the utility model is: an octagonal needle roller guide rail device, the guide rail device includes a body, a slider, a fixed needle roller guide rail seat, a needle roller bearing and an adjustable needle roller guide rail seat;
[0005] Two vertical planes are processed on the rear and left sides of the fuselage respectively;
[0006] There are multiple fixed needle roller guide rail seats, which are fixedly installed on the planes on the rear and left sides of the fuselage respectively;
[0007] There are multiple needle roller bearings, which are respectively arranged on the rear side, left side, front side and right side of the fuselage. The needle roller bearings on the rear side and left side of the fuselage are arranged on fixed needle roller guide rail seats, and the rear side and left side guide surfaces of the slider are in close contact with the needle roller bearings on the rear side and left side of the fuselage; the needle roller bearings on the front side and right side of the fuselage are arranged on adjustable needle roller guide rail seats, and the front side and right side guide surfaces of the slider are in close contact with the needle roller bearings on the front side and right side of the fuselage, and screws are provided on the adjustable needle roller guide rail seats.
[0008] The beneficial effects of the utility model are as follows: the contact surface of the fixed needle roller guide seat is processed on the outside of the fuselage, which is easy to process and easy to ensure the verticality of the installation surface on the left and rear sides of the fuselage; the right and front sides of the fuselage are adjustable needle roller guide seats, which are convenient for adjustment. BRIEF DESCRIPTION OF THE DRAWINGS
[0009] Figure 1 It is a structural diagram of the present utility model.
[0010] In the figure, 1 is the body, 2 is the slider, 3 is the fixed needle roller guide seat, 4 is the needle roller bearing, and 5 is the adjustable needle roller guide seat. DETAILED DESCRIPTION
[0011] An eight-sided needle roller guide device, the guide device comprising a body 1, a slider 2, a fixed needle roller guide seat 3, a needle roller bearing 4 and an adjustable needle roller guide seat 5;
[0012] Two vertical planes are processed on the rear and left sides of the fuselage 1 respectively;
[0013] There are multiple fixed needle roller guide rail seats 3, which are fixedly installed on the planes on the rear and left sides of the fuselage 1;
[0014] There are multiple needle roller bearings 4, which are respectively arranged on the rear, left, front and right sides of the fuselage 1. The needle roller bearings 4 on the rear and left sides of the fuselage 1 are arranged on the fixed needle roller guide seat 3, and the rear and left guide surfaces of the slider 2 are close to the needle roller bearings 4 on the rear and left sides of the fuselage 1; the needle roller bearings 4 on the front and right sides of the fuselage are arranged on the adjustable needle roller guide seat 5, and the front and right guide surfaces of the slider 2 are close to the needle roller bearings 4 on the front and right sides of the fuselage 1. Screws are provided on the adjustable needle roller guide seat 5, and the force of the screws is applied to tightly press the front and right guide surfaces of the slider 2, so that the front and back, left and right positions of the slider 2 are determined.
[0015] The contact surface of the fixed needle roller guide seat 3 of the utility model is processed on the outside of the fuselage 1, which is easy to process and easy to ensure the verticality of the mounting surface on the left and rear sides of the fuselage 1.
