Embodiment 1

[0025] see Figure 1-3 , an O-ring installation protection device, which includes a housing 1, the upper outer wall of the housing 1 is provided with a first pipe joint 5, and the lower outer wall is provided with a second pipe joint 4, the housing 1 The inside of the motor stator 2 is installed by sliding fit, the upper part of the motor stator 2 is provided with a first O-ring seal 7, and the lower part is provided with a second O-ring seal 6; the inside of the motor stator 2 is set with a guide body 3. A pressure head 8 is set on the top of the guide body 3, and the pressure head 8 is connected with the piston rod of the cylinder 9. By adopting the installation protection device with the above-mentioned structure, damage to the O-ring during installation can be effectively prevented. The invention improves the installation efficiency and quality by automatically pressing the sealing ring.

[0026] Further, the inner holes at the upper and lower ends of the housing 1 are c...

Embodiment 2

[0036] The assembly method of any one of the rail-guided and clamping composite devices, which includes the following steps:

[0037] Step1: Place the guide body 3 in the casing 1, place the second O-ring 6 and the first O-ring 7 in the sealing groove of the motor stator 2;

[0038] Step2: Then put the motor stator 2 into the guide body 3. Since the upper and lower outer circles of the guide body 3 have high coaxial precision with the inner hole of the upper end of the housing 1, the two O-rings will The amount of compression remains consistent, and the orifice has been set at the first guide angle A, which effectively prevents the sealing ring from being sheared;

[0039] Step3: The second O-ring seal 6 is positioned here after entering the orifice, the cylinder 9 presses down, the pressure head 8 presses down the motor stator 2, and the second O-ring seal 6 enters the first ring guide at the upper end When slotting, first spread evenly along the second guide bevel B, and en...

Abstract

The invention discloses an installation protection device of O-shaped seal rings and an assembling method. The installation protection device comprises a shell body. A first pipe connector is arrangedon the outer side wall of the upper portion of the shell body. A second pipe connector is arranged on the outer side wall of the lower portion of the shell body. A motor stator is installed in the shell body through sliding fit. The first O-shaped seal ring is arranged at the upper portion of the motor stator, and the second O-shaped seal ring is arranged at the lower portion of the motor stator.A guide body is arranged in the motor stator through sleeving. The top of the guide body is sleeved with a pressing head. The pressing head is connected with a piston rod of a cylinder. By means of the device and method, the O-shaped seal rings can be protected against damage during installing.

Description

technical field [0001] The invention relates to an installation protection device and method, in particular to an O-shaped sealing ring installation protection device and an assembly method. Background technique [0002] In order to reduce the operating temperature of the motor during the use of the machine tool, the motor is often cooled. A cooling groove is provided on the outer circle of the motor stator, and the cooling groove communicates with the cooling water pipe joint. In order to seal the cooling water, O-shaped sealing rings are respectively arranged at the upper and lower ends of the cooling tank of the motor stator. However, in the actual installation process, the O-ring is easily sheared with the housing orifice and the through hole of the pipe joint to damage the sealing ring. Therefore, it is necessary to propose an O-ring installation protection device and method to solve the problem that the existing O-ring is easily damaged during installation. Contents...
