Problems solved by technology

To meet the above requirements, not only a hydraulic press, but also a closed-loop control system with force measuring and distance measuring sensors, the whole system is complex and requires a large investment
And after the taper sleeve is pressed in, there is no corresponding disassembly tool, which is very easy to damage the taper sleeve and destroy the taper hole of the matching parts

Embodiment 1

[0026] A device with distance measurement, fixed force and assembly and disassembly of precision taper sleeves, including a taper sleeve 1, the cross section of the taper sleeve 1 is an inverted T shape, the inside of the taper sleeve 1 is a light hole 101, and the taper sleeve 1 The taper is 1:50, the depth of the light hole 101 is set to 160 mm, the thickness of the taper sleeve 1 is set to 5 mm, the upper and lower surfaces of the taper sleeve 1 are provided with glands, and the glands include an upper gland 2 and a lower gland 3, so The diameter of the upper gland 2 is set to 220mm, and the diameter of the lower gland 3 is set to 216mm. The upper gland 2 is provided with a first positioning notch 204 that cooperates with the light hole 101 of the taper sleeve 1. The first positioning The notch 204 is set through the upper gland 2, and the first relief holes 201 are evenly distributed on the upper gland 2, and the first relief holes 201 are evenly distributed on the circumfe...

Embodiment 2

[0028] This embodiment is further optimized on the basis of embodiment 1, specifically, the number of relief holes is set to six.

[0029] In this embodiment, by providing additional lightening holes, it is convenient to reduce the overall weight of the taper sleeve 1 device, so as to save labor and facilitate the operation of the operator.

Embodiment 3

[0031] This embodiment is further optimized on the basis of Embodiment 1 and Embodiment 2. Specifically, the central rod 5 is set in a cylindrical shape, and the weight 6 is set in a cylindrical shape.

[0032] In this implementation, the frictional force between the weight 6 and the center rod 5 is reduced by setting the center rod 5 and the weight 6 in a cylindrical shape, so as to increase the measurement accuracy.

Abstract

The invention discloses a device with distance measuring, force specifying and dismounting precision taper sleeve. The device comprises a taper sleeve, glands are arranged on an upper surface and a lower surface of the taper sleeve, the glands comprise an upper gland and a lower gland, lightening holes are uniformly distributed in the glands, the edge of the upper gland is provided with radially symmetric notches, the gland is provided with a corresponding positioning spigot, a center rod is connected between the glands, the center rod is in a stair step shape, and a weight is arranged on thecenter rod of the upper gland in a sliding mode. According to the device, the upper gland, the lower gland, the center rod, the weight, a fixing nut and the taper sleeve are combined into a whole, sothat the problem that the taper sleeve is mounted and taken out is solved, and the assembly is more convenient. According to the designed weight and the length of the center rod, the requirement for specified gravity required by mounting taper sleeve is guaranteed, and the top of the center rod is impacted upwards through the weight, so that the taper sleeve can be easily separated from the matched taper hole. The purpose of not damaging the taper sleeve and the taper hole part is achieved. The design of the notch of the upper gland meets the requirement that the distance between the top of the taper sleeve and the conical hole surface is measured.

Description

technical field [0001] The invention relates to technologies such as mechanical assembly and measurement, in particular to a device for determining force, measuring distance, and assembling and disassembling precision taper sleeves. Background technique [0002] There is a large taper hole on a part, the taper is 1:50, and the depth of the taper hole is 160mm. A thin-walled taper sleeve with an average thickness of 5mm needs to be assembled, and the contact between them is detected through the taper sleeve. Technical requirements for parts; the taper sleeve coated with a certain amount of ink pad is pressed into the taper hole of the part with a constant force of 25±5kg, and the distance between the large end of the taper sleeve and the large hole surface of the taper hole is Then, the taper sleeve is taken out, and the contact surface of the taper surfaces of the two parts is detected to be greater than 80%. To meet the above requirements, not only a hydraulic press, but ...
