Description

Technical Field

[0001] This utility model belongs to the field of shell processing and relates to a shot blasting machine for producing air conditioner compressor shells. Background Technology

[0002] A tracked shot blasting machine is a device used to clean and strengthen the surface of metal workpieces. When applied to the production of air conditioner compressor housings, it primarily utilizes a high-speed rotating impeller to propel shot, such as steel shot or iron shot, onto the surface of the compressor housing. Tracked shot blasting machines can achieve automated continuous operation, processing multiple air conditioner compressor housings at a time. Compared to traditional manual or chemical cleaning methods, it significantly increases the speed of cleaning and strengthening, meeting the needs of large-scale production.

[0003] When the air conditioner compressor housing falls directly onto the conveyor belt after shot blasting without any cushioning, the housing, which is usually made of metal and is quite heavy, will generate a large impact force when it collides with the conveyor belt. A large number of uncushioned air conditioner compressor housings falling directly onto the conveyor belt will cause frequent impact wear on the conveyor belt, further reducing the overall precision of the equipment. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned problems in the existing technology by providing a shot blasting machine for auxiliary discharge of air conditioner compressor housings.

[0005] The objective of this utility model can be achieved through the following technical solutions:

[0006] A shot blasting machine for producing air conditioner compressor housings includes a shot blasting chamber. The machine features a processing cavity at its front end, auxiliary internal drive turntables symmetrically arranged on the left and right inner walls of the processing cavity, a circulating track block at the inner end of the processing cavity, the circulating track block cooperating with the auxiliary internal drive turntables, an electric transmission belt at the front end of the shot blasting chamber, an electric transmission belt between the shot blasting chamber and the electric transmission belt, a rotating shaft crossbar at one end of the electric transmission belt near the shot blasting chamber, multiple receiving buffer crossbars fixedly connected to the outer end of the rotating shaft crossbar, the multiple receiving buffer crossbars being arranged equidistantly in a ring, and a pair of symmetrical elastic telescopic members fixedly connected to the end of each receiving buffer crossbar away from the rotating shaft crossbar.

[0007] In the aforementioned air conditioner compressor housing production belt shot blasting machine, the two corresponding elastic telescopic members on the left and right sides are provided with a sponge contact strip at the end away from the rotating shaft crossbar, and the sponge contact strip is in contact with the outer wall of the circulating track block.

[0008] In the aforementioned air conditioner compressor housing production belt shot blasting machine, the material conveying bin and the shot blasting bin are interconnected.

[0009] In the aforementioned air conditioner compressor housing production belt shot blasting machine, the upper end of the electric transmission belt is provided with a single external surface layer, and the single external surface layer and the electric transmission belt are provided with a plurality of buffer rebound inner balls at the ends close to each other.

[0010] In the aforementioned shot blasting machine for producing air conditioning compressor housings, the upper and lower ends of the buffer rebound inner ball are symmetrically provided with arc-shaped inner connecting parts, and the upper and lower arc-shaped inner connecting parts are connected to the single outer surface layer and the electric transmission belt at their respective ends.

[0011] In the aforementioned shot blasting machine for producing air conditioner compressor housings, the buffer rebound inner ball and the arc-shaped inner connector are both fixedly connected to each other at their close ends with an extrusion-resistant filling layer, and the inner end of the processing cavity is filled with several housing workpieces.

[0012] In the aforementioned air conditioner compressor housing production belt shot blasting machine, several housing workpieces are moved to the top of the electric conveyor belt for transfer via a receiving buffer crossbar, and a motor is connected to the outside of the rotating shaft crossbar.

[0013] In the aforementioned air conditioning compressor housing production belt shot blasting machine, the inner end of the water-cooled trough is filled with a number of finished jelly products, which are moved above the drying horizontal conveyor belt by a slant lifting conveyor belt.

[0014] Compared with existing technologies, this air conditioner compressor housing production belt shot blasting machine first places the housing workpiece into the surface of the circulating track block of the shot blasting chamber for shot blasting. During discharge, the motor drives the rotating shaft crossbar to rotate, filling the gap at the outlet of the processing cavity and buffering the drop force of the workpiece. The rotation of the rotating shaft crossbar drives the receiving buffer crossbar to move. Its outer sponge contact strip scrapes off impurities on the outside of the circulating track block after being abutted by the elastic telescopic component, thus optimizing the working environment. After shot blasting, the housing workpiece falls onto the electric conveyor belt. The buffer rebound inner ball between the single outer surface layer above it and the electric conveyor belt can buffer the impact force of the workpiece. The compression-resistant filling layer ensures the stable operation of the buffer rebound inner ball, reduces the risk of workpiece damage, ensures quality, and facilitates subsequent processes.

[0022] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "or / and" as used herein includes any and all combinations of one or more of the associated listed items.

[0023] like Figure 1 As shown in Figure 4, the air conditioner compressor housing production using a shot blasting machine includes a shot blasting chamber 1. The front end of the shot blasting chamber 1 has a processing inner cavity 2. The left and right inner walls of the processing inner cavity 2 are symmetrically provided with auxiliary inner drive turntables 3. The inner end of the processing inner cavity 2 is provided with a circulating track block 4. The circulating track block 4 cooperates with the auxiliary inner drive turntable 3. The front end of the shot blasting chamber 1 is provided with an electric transmission belt 5. An electric transmission belt 5 is provided between the shot blasting chamber 1 and the electric transmission belt 5. The end of the electric transmission belt 5 near the shot blasting chamber 1 is provided with a rotating shaft crossbar 6. The outer end of the rotating shaft crossbar 6 is fixedly connected with multiple receiving buffer crossbars 7. The multiple receiving buffer crossbars 7 are arranged in a ring at equal intervals. The end of the receiving buffer crossbar 7 away from the rotating shaft crossbar 6 is fixedly connected with a pair of left and right symmetrical elastic telescopic members 8.

[0024] Two elastic telescopic members 8, corresponding to each other on the left and right, are provided with a sponge contact strip 9 at the end away from the pivot bar 6. The sponge contact strip 9 is in contact with the outer wall of the circulating track block 4.

[0025] The rear end of the shot blasting chamber 1 is provided with a material conveying chamber 10, and the material conveying chamber 10 and the shot blasting chamber 1 are interconnected.

[0026] The upper end of the electric conveyor belt 5 is provided with a single external surface layer 13, and a plurality of buffer rebound inner balls 12 are provided at the end of the single external surface layer 13 and the electric conveyor belt 5 that are close to each other.

[0027] The upper and lower ends of the buffer rebound inner ball 12 are symmetrically provided with arc-shaped inner connectors 11, and the upper and lower arc-shaped inner connectors 11 are connected to the single outer surface layer 13 and the electric transmission belt 5 at their respective close ends.

[0028] The inner ball 12 and the arc-shaped inner connector 11 are both fixedly connected to each other at their close ends with a compression-resistant filling layer 14, and the inner end of the processing cavity 2 is filled with several shell workpieces.

[0029] Several of the aforementioned shell workpieces are moved above the electric conveyor belt 5 via the receiving buffer crossbar 7 for transfer, and the rotating shaft crossbar 6 is externally connected to a motor.

[0030] In this scheme, the shell workpiece is filled into the shot blasting chamber 1 to start the shot blasting process. Since there is a certain drop at the outlet of the processing cavity 2, if the shell workpiece falls directly, it will inevitably bear a large drop force. Therefore, when the rotating shaft crossbar 6 rotates, the receiving buffer crossbars 7, evenly distributed at its outer end, also move synchronously. At this time, the sponge contact strip 9 connected to the outer side of the receiving buffer crossbar 7, under the action of the elastic telescopic component 8, can achieve a precise abutment action. Once the sponge contact strip 9 abuts, it will make close contact with the outer side of the circulating track block 4. During long-term operation, various impurities inevitably adhere to the outer side of the circulating track block 4. The sponge contact strip 9, with its unique material properties and contact method, can gently and effectively assist in scraping away these impurities. In this way, not only can the cleanliness of the outer side of the circulating track block 4 be maintained, but also... Its stable and efficient operation also contributes to the optimization of the entire shot blasting environment. Multiple buffer rebound inner balls 12 are arranged between the single outer surface layer 13 and the electric conveyor belt 5. These buffer rebound inner balls 12 can effectively absorb and disperse the impact force carried by the shell workpiece when it falls onto the electric conveyor belt 5, thus providing further buffer protection for the shell workpiece. Furthermore, a compression-resistant filling layer 14 is provided at the end of the buffer rebound inner ball 12 that is close to the arc-shaped inner connector 11 to provide solid support and stable constraint for the buffer rebound inner ball 12. This ensures that the buffer rebound inner ball 12 can always maintain a relatively stable and reliable working state when it is under pressure and performing rebound action, effectively guaranteeing the quality and integrity of the shell workpiece and laying a solid foundation for the subsequent air conditioning compressor processing.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0032] Those skilled in the art should recognize that the above embodiments are only used to illustrate the present utility model and are not intended to limit the present utility model. Any appropriate changes and variations made to the above embodiments within the scope of the essential spirit of the present utility model shall fall within the scope of protection claimed by the present utility model.
