Problems solved by technology

[0005] However, due to the integrated structure of the rod and the base in the existing universal ball bearing, the rod and the base have the same high hardness
The shaft with higher hardness may be damaged due to its rigidity during use
Moreover, due to the relatively high hardness of the rod part, the rod part of the universal ball will also be stressed during use. Once the threaded part of the rod part is damaged by force (the higher hardness rod part makes it very brittle, once it is stressed, it will will be easily broken) can also lead to problems of weak connection between the universal ball and other equipment

Embodiment 1

[0057] Such as figure 1 As shown, the universal ball base 1 includes a base head 1a and a base rod 1b that are connected as a whole. The base head 1a is cylindrical, the base rod 1b is rod-shaped, the base rod 1b has threads on the outside, and the base head The outer end of 1a has an aperture groove 1a1 recessed in a spherical surface. The inner end of the base head 1a and the inner end of the base rod 1b are integrally connected.

[0058] The processing method of the universal ball base includes the following steps:

[0059] A. Turning blank: cut off the raw material bar or obtain a set length of the bar blank by metal forging. After the bar blank is clamped on the lathe, the base is processed on the bar blank by turning processing method The head 1a is a semi-finished product.

[0060] After the semi-finished product is turned around and clamped on the lathe, the rod-shaped base rod portion 1b is processed by a turning method. In this embodiment, an additional process is adde...

Embodiment 2

[0071] The processing method of the universal ball base includes the following steps:

[0072] A. Turning blank: Cut off the raw material bar or obtain a set length of the bar blank by metal forging, and then clamp the bar blank on the lathe, and then process the base on the bar blank by turning processing method The head 1a is a semi-finished product.

[0073] After the semi-finished product is turned around and clamped on the lathe, the rod-shaped base rod portion 1b is processed by a turning method. In this embodiment, an additional process is added during the turning process, that is, chamfering the edges of the base head 1a and the base rod 1b. Of course, according to the actual situation, the edges of the base head 1a and the base rod 1b may also be rounded.

[0074] Finally, thread rolling or thread rolling is used to process the external thread on the base rod.

[0075] B. Machining caliber groove: The outer end of the base head 1a is rough turned by a turning method to obta...

Embodiment 3

[0083] The processing method of the universal ball base includes the following steps:

[0084] A. Turning blank: cut off the raw material bar or obtain a set length of the bar blank by metal forging. After the bar blank is clamped on the lathe, the head is processed on the bar blank by turning processing method Part 1a, a semi-finished product is obtained.

[0085] After the semi-finished product is turned around and clamped on the lathe, the rod-shaped base rod portion 1b is processed by a turning method. In this embodiment, an additional process is added during the turning process, that is, chamfering the edges of the base head 1a and the base rod 1b. Of course, according to the actual situation, the edges of the base head 1a and the base rod 1b may also be rounded.

[0086] Finally, an external thread is processed on the base rod 1b by a thread rolling or thread rolling processing method.

[0087] B. Machining caliber groove: The outer end of the base head is rough-turned by a tu...

Abstract

The invention provides a method for machining a universal ball pedestal and belongs to the technical field of machinery. The problem that the rod part of the current universal ball pedestal is easy to break is solved. The method for machining the universal ball pedestal provided by the invention comprises the following steps of A, turning a blank; B, machining a caliber groove; C, thermally treating the whole pedestal; D, performing high-frequency quenching on the head of the pedestal; E, sanding. The method for machining the universal ball pedestal provided by the invention has the advantage that the hardness of the head of the pedestal and the hardness of the rod part of the pedestal are different.

Description

Technical field [0001] The invention belongs to the technical field of machinery, and relates to a universal ball, especially a method for processing a base in the universal ball. Background technique [0002] The universal ball can carry light and heavy objects to move horizontally in all directions, and is suitable for machinery, hardware, chemical, food, supermarket, airport, warehouse and other industries. It is widely used in logistics and transmission industries for mechanical loading, assembly lines, conveyors, conveyors and other conveying equipment, as well as the turning and merging parts of objects. [0003] The universal ball includes a ball, a base, a cover plate and a marble layer. The end of the base has a spherical concave aperture groove. The ball is located at the aperture groove and the above-mentioned marble layer is located between the ball and the base. The cover plate is located in the circle. On the outer side of the bead, a round hole for the part of the b...
