Description

Technical Field

[0001] The utility model relates to the technical field of back-shaft chucks, in particular to a back-shaft material discharging structure for realizing rapid material discharging of a pressure sleeve. Background Art

[0002] As the core component of the knock sensor, the KS4 pressure sleeve has very high requirements for its processing in production. The current processing equipment used is the SF26 multi-axis machine with a cycle of 2.8s and an efficiency of 75%. Although the production efficiency has reached a good level, facing the market demand, the existing processing production efficiency is still under great pressure in the face of delivery volume. If there is a problem with the equipment, there will be a risk of supply interruption. Therefore, the improvement of production efficiency is still an urgent problem to be solved. To improve production efficiency, we must first improve the cycle of the equipment production process, and then improve production efficiency. In the face of equipment transformation, if the existing equipment is improved as a whole, the cycle is long and the transformation cost is high, which cannot meet the existing needs in time. The existing back-shaft end processing discharging structure, such as Figure 2 As shown, the back shaft needs to cooperate with the ejector rod when discharging the material. The process in production and processing is: the back shaft chuck is installed on the back shaft of the machine tool. When the back shaft size processing is completed, the back shaft moves backward, the chuck opens, and the connecting rod inside the back chuck moves until it touches the back shaft ejector rod. The back shaft ejector rod ejects the part. At this time, the processing of one part is completed, and then the next part can be processed. The above processing method is conventional. Although there is no problem in realizing production, the processing cycle is reduced due to the processing steps. Therefore, the improvement of the processing and discharging of the back shaft end is particularly important for improving processing efficiency. Utility Model Content

[0003] The technical problem solved by the utility model is to provide a back-shaft material discharging structure which can be used to realize rapid coating of a pressure sleeve, thereby improving the processing rhythm and the production efficiency.

[0004] In order to solve the above technical problems, a technical solution adopted by the utility model is:

[0005] A back-shaft material discharging structure for realizing rapid material discharging of a pressure sleeve, comprising: a back-shaft chuck, the back-shaft chuck being connected to a back-shaft of a machine tool;

[0006] A connecting rod is provided in the back shaft chuck, and an elastic member and a fixing block are sleeved on the connecting rod;

[0007] The top material block is fixed on the front end of the connecting rod by a fixing pin.

[0008] Preferably, the elastic member is located between the fixing block and the lifting block.

[0009] Preferably, the elastic member is a spring.

[0010] Preferably, the back spindle chuck is connected to the machine tool back spindle via threads.

[0011] The beneficial effects of the utility model are:

[0012] The utility model discloses a back-shaft discharging structure for realizing fast discharging of a pressure sleeve. The structure is simple, the processing is faster and the modification cost is low. An elastic part is sleeved on a connecting rod. When the back-shaft size processing is completed, the back-shaft moves backward and the back-shaft chuck is opened. Under the elastic action of the spring, the spring can directly push out the part. When discharging, the back-shaft ejecting rod is no longer needed to push out the part to complete the discharging. The processing steps are simplified, the discharging is faster, thereby saving the processing time and improving the production efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0018] Example:

[0019] This embodiment introduces a back-shaft material discharging structure for realizing rapid material discharging of a pressure sleeve, and combines the attached Figure 1 As shown, Figure 1 The utility model is a schematic diagram of a spring chuck structure used in the production of a pressure sleeve.

[0020] A back-shaft material discharging structure for realizing rapid material discharging of a pressure sleeve, comprising: a back-shaft chuck 1, wherein the back-shaft chuck 1 is connected to a machine tool back-shaft through threads;

[0021] The back shaft chuck 1 is provided with a connecting rod 2, and an elastic member 3 and a fixing block 4 are sleeved on the connecting rod 2;

[0022] The top material block 5 is fixed on the front end of the connecting rod by a fixing pin 6 .

[0023] Furthermore, the elastic member 3 is located between the fixing block 4 and the lifting block 5 .

[0024] Furthermore, the elastic member 3 is a spring.

[0025] The existing back-shaft discharging structure, such as Figure 2 As shown, during the processing, after the back-shaft size processing is completed, the back-shaft moves backward, the back-shaft chuck opens, and the connecting rod inside the back-shaft chuck moves until it hits the back-shaft ejector rod. The back-shaft ejector rod ejects the parts on the back-shaft chuck to complete the discharging process. Under the existing discharging structure processing steps, the processing cycle is 2.8s, and the efficiency is 75%. Compared with this embodiment, by setting a spring on the connecting rod and replacing the ejector rod in the existing structure with the spring, the back-shaft ejector rod is no longer required to eject the parts to complete the discharging when discharging. That is, when the back-shaft size processing is completed, the back-shaft moves backward, the back-shaft chuck opens, and under the elastic action of the spring, the spring can directly eject the parts to complete the discharging. There are no other redundant processing steps. Under this processing step, it is found through actual production that the processing cycle saves 0.5 seconds and the production efficiency is improved by 17.8%.

[0026] Therefore, it can be seen from the above text description and the accompanying drawings that the back-shaft discharging structure provided by the utility model for realizing rapid discharging of the pressure sleeve utilizes the elastic mechanical properties of a simple spring to realize rapid discharging of the back-shaft chuck after it is opened, and no other unnecessary process steps are required at the back-shaft end. This greatly improves production efficiency without the need for high-cost equipment modification.
