DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] A car air conditioning clutch pulley spinning device, such as Figure 1 and Figure 2 As shown, it includes a support frame 1, a first electric telescopic rod 2, a first motor 3, a pressing block 4, a placement frame 5, a second motor 6, a bidirectional screw rod 7, a slider 8, a second electric telescopic rod 9, a mounting frame 10, a spinning wheel 11, a fixing mechanism 12 and a scraping mechanism 13. The first electric telescopic rod 2 is connected to the upper side of the support frame 1, the first motor 3 is connected to the telescopic end of the first electric telescopic rod 2, the pressing block 4 is connected to the output shaft of the first motor 3, the placement frame 5 is rotatably connected to the lower part of the support frame 1, the second motor 6 is connected to the right side of the support frame 1, the bidirectional screw rod 7 is rotatably connected to the lower part of the support frame 1, the bidirectional screw rod 7 is connected to the motor output shaft, the left and right parts of the bidirectional screw rod 7 are both threadedly connected to the slider 8, the upper side of the slider 8 is connected to the second electric telescopic rod 9, the second electric telescopic rod 9 is connected to the mounting frame 10, the spinning wheel 11 is clamped on the mounting frame 10, the placement frame 5 is provided with a fixing mechanism 12, and the mounting frame 10 is provided with a scraping mechanism 13.

[0021] like Figure 1 and Figure 3As shown, the fixing mechanism 12 includes a guide rod 121, an extrusion block 122, a first telescopic spring 123, a sleeve 124, a pressing frame 125 and a second telescopic spring 126. A plurality of groups of guide rods 121 are connected to the placement frame 5, each group consisting of two upper and lower guide rods 121. Extrusion blocks 122 are slidably connected between the guide rods 121 of the same group. The outer side of the extrusion blocks 122 is arc-shaped, which is convenient for fixing the hollow blank. The first telescopic spring 123 is connected between the guide rods 121 and the adjacent extrusion blocks 122. A sleeve 124 is connected to the middle part of the placement frame 5. A pressing frame 125 is slidably connected to the sleeve 124. A second telescopic spring 126 is connected between the pressing frame 125 and the sleeve 124. The pressing frame 125 is extruded and matched with the extrusion block 122.

[0022] When using the utility model, first place the support frame 1 on the spinning area of ​​the automobile air-conditioning clutch pulley, then place the hollow blank on the placement frame 5, then start the first electric telescopic rod 2, push out the telescopic end of the first electric telescopic rod 2, and make the pressing block 4 move downward to contact the hollow blank, so as to press and fix the hollow blank. When the pressing block 4 moves downward, the pressing frame 125 is squeezed to slide downward on the sleeve 124, and the second telescopic spring 126 is squeezed and contracted. Through the extrusion cooperation between the pressing frame 125 and the extrusion block 122, the extrusion block 122 slides outward, and the first telescopic spring 123 is stretched, so that the extrusion block 122 contacts the hollow blank, and the hollow blank is fixed. The hollow blank is clamped and fixed, thereby preventing the hollow blank from sliding and deviating during spinning, which affects the processing quality of the pulley. Then, the first motor 3 is started to rotate the pressing block 4, so that the hollow blank and the placement rack 5 rotate synchronously. After the hollow blank rotates, the second electric telescopic rod 9 is started to push out the telescopic end of the second electric telescopic rod 9, and the spinning wheel 11 is moved to the height at which the hollow blank needs to be spun. Then, the second motor 6 is started to rotate the bidirectional screw rod 7, driving the slider 8 to approach each other, so that the spinning wheels 11 approach each other and contact with the hollow blank, and the hollow blank is spun into the shape of a pulley. The scraping mechanism 13 can clean the spinning wheel 11.

[0023] like Figure 1 and Figure 4As shown, a scraping mechanism 13 is also included, and the scraping mechanism 13 includes a screw 131, a rotating handle 132, a scraper 133, a sliding block 134, a limiting rod 135 and a third telescopic spring 136. The mounting frame 10 is threadedly connected with the screw 131, and the rotating handle 132 is connected on the side of the screw 131 away from each other, and a scraper 133 is provided on the side of the screw 131 close to each other. The lower side of the scraper 133 is connected with a sliding block 134, and the sliding block 134 is slidably connected to the adjacent mounting frame 10. The scraper 133 is slidably connected with a limiting rod 135, and the limiting rod 135 is connected to the adjacent scraper 133 with a third telescopic spring 136. The limiting rod 135 is clamped with the adjacent screw 131, and a clamping hole is opened on the screw 131 to facilitate the clamping with the scraper 133.

[0024] The scraper mechanism 13 of the present device can be used to scrape the blank attached to the spinning wheel 11. When the spinning wheel 11 rotates, the adjusting screw 131 is rotated by rotating the handle 132, and the screw 131 is moved under the action of the thread, driving the scraper 133 to move to contact the spinning wheel 11, and the blank attached to the spinning wheel 11 is scraped, thereby cleaning the blank attached to the spinning wheel 11, avoiding the quality degradation of the pulley, and increasing the service life of the spinning wheel 11. After replacing the spinning wheel 11 of different sizes, the sliding limiting rod 135 is disengaged from the screw 131, and the third telescopic spring 136 is squeezed and contracted, and then the specified scraper 133 is replaced according to the size of the spinning wheel 11, and then the third telescopic spring 136 is rebounded, driving the limiting rod 135 to re-engage with the screw 131, so as to facilitate the scraping of the blanks on the spinning wheels 11 of different sizes.

[0025] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
