In this process, the piston heat treatment transmission device is indispensable.

[0003] A document with prior art publication number CN 118255102 B provides a conveying device for heat treatment, which uses a large chain, a driving power structure and a large flywheel to enable support shafts and conveying rollers to cyclically pass through heat treatment equipment.

[0077] The present invention will be further described in detail below by enumerating embodiments of the present invention in conjunction with the accompanying drawings.

[0078] Reference Figure 1-Figure 9 The embodiment of the present application discloses a conveying device for piston heat treatment, which includes: a support frame 1, a transmission mechanism, a receiving plate 3, a heat uniforming component 7, a stabilizing mechanism and a chip cleaning component 5.

[0079] Among them, the transmission mechanism is used to drive the receiving plate 3 to move into the heat treatment furnace body, and the transmission mechanism includes two sets of transmission chains 2 installed on the support frame 1, and the support frame 1 is also equipped with a driving mechanism, and the driving mechanism is used to drive the transmission chain 2 to rotate; the receiving plate 3 is fixedly installed between the two transmission chains 2, and a placement cylinder 6 is fixedly installed on the receiving plate 3; the uniform heating component 7 is used to ensure that the piston is heated evenly during the heat treatment process; the stabilizing mechanism is used to ensure that the piston inverted on the placement cylinder 6 remains stable during the heat treatment process, and the stabilizing mechanism includes an adsorption component 8 and an internal support component 9. The adsorption component 8 includes a receiving cylinder 802 fixedly connected to the placement cylinder 6, and a plurality of rubber suction cups 806 are fixedly connected to the receiving cylinder 802. The rubber suction cup 806 is made of high-temperature resistant rubber material, and the internal support component 9 is used to further fix the piston; the chip cleaning component 5 is used to remove metal debris in the rubber suction cup 806.

[0080] When the long piston needs to be heat treated, the staff will set the piston sleeve on the outside of the placement tube 6. After the piston is placed, the driving mechanism is operated under the control of the external control mechanism, and the transmission chain 2 drives the receiving plate 3 and the piston on the placement tube 6 to gradually move into the furnace body. This vertical placement method can prevent the long piston from bending and deforming due to its own weight, especially at high temperatures, which reduces the strength of the material and causes uneven heating, effectively improving the uniformity of heating of the piston during heat treatment; in addition, the rubber suction cup 806 contacts the top of the inner side of the piston, which can not only provide protection and buffering, but also the piston can be adsorbed on the surface of the piston to prevent the piston from moving randomly during the movement, causing bumps and other effects on the piston quality and heat treatment effect.

[0081] Reference Figure 1 and Figure 2 The piston heat treatment conveying device provided in the embodiment of the present application has a driving mechanism including a motor 10 and two sets of sprockets 4.

[0082] The sprocket 4 is rotatably connected to the support frame 1 , and the sprocket 4 is meshed with the transmission chain 2 for transmission; the motor 10 is arranged on one side of the support frame 1 , and the output end of the motor 10 is fixedly connected to one of the sprockets 4 .

[0083] Under the action of the motor 10, the sprocket 4 rotates, and the transmission chain 2 then drives the receiving plate 3 to move.

[0084] Reference Figure 1 , Figure 2 and Figure 3 The piston heat treatment conveying device provided in the embodiment of the present application has a placement cylinder 6 rotatably penetrated on the receiving plate 3, and the heat uniforming component 7 includes a fixed rack 701, a support plate 704 and a first bevel gear 705.

[0085] Among them, the fixed rack 701 is installed on one side of the transmission chain 2; one side of the support plate 704 is rotatably connected to the driving gear 702, and the driving gear 702 is meshed with the fixed rack 701; the other side of the support plate 704 is rotatably connected to the second bevel gear 703, the second bevel gear 703 is connected and fixed to the driving gear 702, and the second bevel gear 703 is vertically meshed with the first bevel gear 705.

[0086] After the receiving plate 3 drives the placement cylinder 6 and the piston on its upper side to enter the heat treatment furnace body, the driving gear 702 will gradually engage with the fixed rack 701. Under the connection between the second bevel gear 703 and the first bevel gear 705, the placement cylinder 6 will drive the piston on its upper side to rotate slowly, thereby changing the position of the piston, thereby further improving the uniformity of heating of the piston during heat treatment.

[0087] Reference Figure 3 , Figure 4 , Figure 5 and Figure 6 The piston heat treatment conveying device provided in the embodiment of the present application, the adsorption component 8 also includes a vacuum plate 803, a lower pull rod 807 and a lifting mechanism.

[0088] Among them, the air extraction plate 803 is slidably connected to the receiving tube 802; the lower pull rod 807 is connected and fixed to the air extraction plate 803; and the lifting mechanism is used to drive the lower pull rod 807 to move up and down.

[0089] After the piston is placed above the rubber suction cup 806, under the action of the lifting mechanism, the lower pull rod 807 drives the vacuum plate 803 to move downward. At this time, the residual gas in the vacuum plate 803 will be sucked into the receiving tube 802, so that the rubber suction cup 806 can be more tightly adsorbed on the piston, which can not only further improve the stability of the piston during heat treatment, but also allow the placement tube 6 to drive the piston to rotate more smoothly.

[0090] On the basis of the above scheme, the piston heat treatment conveying device provided in the embodiment of the present application has a lifting mechanism including a storage shell 801, a mounting frame 804, a limiting rotation groove 808, a limiting rod 809, a first spring 810 and a downward pressure guide frame 812.

[0091] Among them, the storage shell 801 is fixedly connected to one side of the placement tube 6; the mounting frame 804 is fixedly installed on one side of the receiving plate 3, and a limiting slide groove 805 is provided on one side of the mounting frame 804; the first spring 810 is fixedly connected between the pull-down rod 807 and the storage shell 801, and the setting of the first spring 810 can not only play a certain supporting effect, but also assist the pull-down rod 807 in resetting; a guide frame 815 is fixedly installed on one side of the downward pressure guide frame 812, and the guide frame 815 is arranged in an open structure. The setting of the guide frame 815 allows the guide rod 811 to smoothly enter the downward pressure guide frame 812 and the lifting guide frame 813, and the lifting guide frame 813 is fixedly installed on the other side of the downward pressure guide frame 812. The guide frames 813 are all arranged in an L-shaped structure; a plurality of limit bars 814 are fixedly installed on the limit rod 809, and the limit bars 814 are slidably connected to the limit slide groove 805. The end of the limit rod 809 is arranged in a T-shaped structure, and the end of the limit rod 809 is limited and rotated in the limit rotation groove 808. Through the arrangement of the limit bars 814, the limit slide groove 805 and the limit rotation groove 808, the placement tube 6 drives the pull-down rod 807 to rotate as a whole, and the pull-down rod 807 can also drive the vacuum plate 803 to move up and down smoothly, thereby ensuring the smooth operation of the present technical solution. A guide rod 811 is installed on the other side of the limit rod 809, and the guide rod 811 is slidably matched with the downward pressure guide frame 812, the lifting guide frame 813 and the guide frame 815.

[0092] As the receiving plate 3 and the placing tube 6 continue to move, the guide rod 811 first contacts the guide frame 815, then smoothly enters into the downward pressure guide frame 812, and slides along the internal contour of the downward pressure guide frame 812. During this period, the guide rod 811 drives the limit rod 809, the lower pull rod 807 and the vacuum plate 803 to move downward for a certain distance, and then keeps the vacuum plate 803 in a fixed position until the end of the heat treatment. The guide rod 811 contacts the lifting guide frame 813. At this time, under the restriction of the lifting guide frame 813, the lower pull rod 807 will drive the vacuum plate 803 to move upward, so that the gas in the receiving tube 802 flows into the rubber suction cup 806, thereby prompting the rubber suction cup 806 to separate from the inner wall of the piston, making it convenient for the staff to disassemble the piston after heat treatment.

[0093] Reference Figure 2 , Figure 4 , Figure 5 , Figure 6 and Figure 8 In the piston heat treatment conveying device provided in the embodiment of the present application, the inner support assembly 9 includes a plurality of telescopic support rods and a pushing mechanism.

[0094] Among them, the telescopic support rod includes a driving rack 905, which is inserted into the storage shell 801, and a contact rod 906 is slidably inserted into one side of the driving rack 905, and a second spring 904 is fixedly connected between the driving rack 905 and the contact rod 906. In this way, the contact rod 906 has a certain degree of elasticity, which is not only suitable for pistons of different specifications and sizes, but also can avoid damage to the piston due to excessive internal support force; the pushing mechanism is used to drive the driving rack 905 to move linearly to one side.

[0095] While the rubber suction cup 806 is adsorbing the piston, the pushing mechanism drives the rack 905 to drive the contact rod 906 to move outward, and the contact rod 906 will gradually contact the inner wall of the piston to support and clamp the piston internally, further improving the stability of the piston during heat treatment.

[0096] On the basis of the above scheme, the transmission device for piston heat treatment provided in the embodiment of the present application, the driving mechanism includes a driving block 907, a power rack 901 and a gear set.

[0097] Among them, the driving block 907 is arranged in a prism-shaped structure, and the driving block 907 is connected and fixed to the lower pull rod 807; the inner end of the power rack 901 is arranged in a bevel structure, and the power rack 901 is slidably connected to the storage shell 801, and the inner end of the power rack 901 is limited to slide on the outside of the driving block 907; the gear set includes a first connecting gear 902 rotatably connected to the storage shell 801, the first connecting gear 902 is meshingly connected to the power rack 901, and a second connecting gear 903 is fixedly connected to one side of the first connecting gear 902, the diameter of the second connecting gear 903 is larger than the diameter of the first connecting gear 902, and the second connecting gear 903 is meshingly connected to the driving rack 905.

[0098] When the lower pull rod 807 moves downward, the driving block 907 moves along with it, and the power rack 901 moves a certain distance inward. Under the connection of the first connecting gear 902 and the second connecting gear 903, the driving rack 905 drives the contact rod 906 to move outward; and when the lower pull rod 807 is reset upward, the driving rack 905 will also drive the contact rod 906 to reset inward, thereby releasing the restriction on the piston and ensuring that the staff can disassemble the piston smoothly.

[0099] Reference Figure 1 , Figure 6 , Figure 7 and Fig. 9 In the piston heat treatment conveying device provided in the embodiment of the present application, the chip cleaning assembly 5 includes a cleaning rod 507 and a third spring 508 .

[0100] The cleaning rod 507 is slidably disposed on the vacuum plate 803 , and the cleaning rod 507 is plugged into and matched with the rubber suction cup 806 ; the third spring 508 is fixedly connected between the cleaning rod 507 and the vacuum plate 803 .

[0101] When the transmission chain 2 drives the receiving plate 3 to move downward, the placement cylinder 6 is in an inverted state. At this time, under the action of gravity, the cleaning rod 507 will slide downward into the rubber suction cup 806, and push out the metal debris such as the skin produced by the heat treatment of the piston remaining in the rubber suction cup 806, to prevent this part of the debris from affecting the subsequent placement of the piston.

[0102] On the basis of the above scheme, the conveying device for piston heat treatment provided in the embodiment of the present application, the chip cleaning component 5 also includes a rotating roller 504, a magnet 506, a collection box 502 and a driving mechanism.

[0104] When the placement tube 6 moves to the top of the magnet 506, under the magnetic force of the magnet 506, the cleaning rod 507 can enter the rubber suction cup 806 more quickly and smoothly to push out the metal debris. At the same time, the magnet 506 can also absorb the debris on the surface of the placement tube 6 and the rubber suction cup 806, thereby improving the cleaning effect of the metal debris. In this process, the driving mechanism operates, the magnet 506 will continue to rotate, and the scraper 503 will scrape the debris absorbed on its surface into the collection box 502, which can not only ensure the absorption effect of the magnet 506, but also facilitate the staff to handle the debris.

[0106] During the rotation of the sprocket 4, the magnet 506 rotates due to the connection between the driving wheel 505 and the belt 501.

[0107] The piston heat treatment transmission process described in this embodiment is implemented based on any piston heat treatment transmission device, and is characterized in that it includes the following steps:

[0108] S1, the staff sets the piston on the outside of the placement cylinder 6, the motor 10 runs, and the transmission chain 2 drives the receiving plate 3 and the piston on the placement cylinder 6 to gradually move into the furnace body;

[0109] S2. As the receiving plate 3 and the placing tube 6 continue to move, the guide rod 811 drives the lower pull rod 807 and the suction plate 803 to move downward, thereby increasing the suction force of the rubber suction cup 806;

[0110] S3, during the downward movement of the lower pull rod 807, the rack 905 drives the contact rod 906 to move outward, and the contact rod 906 gradually contacts the inner wall of the piston to support and clamp the piston;

[0112] S5, when the transmission chain 2 drives the receiving plate 3 to move downward, the cleaning rod 507 enters the rubber suction cup 806 to push out the metal debris;

[0113] S6. Under the connection between the driving wheel 505 and the belt 501 , the magnet 506 rotates continuously, and the scraper 503 scrapes the debris adsorbed on its surface into the collection box 502 .

[0114] The implementation principle of a conveying device for piston heat treatment in an embodiment of the present application is as follows: when relevant staff need to use the present technical solution to transport the piston during heat treatment, the staff first sets the piston on the outside of the placement cylinder 6, and under the control of the external control mechanism, the motor 10 runs, the sprocket 4 rotates, and the transmission chain 2 drives the receiving plate 3 and the piston on the placement cylinder 6 to gradually move into the furnace body.

[0115] As the receiving plate 3 and the placing tube 6 continue to move, the guide rod 811 first contacts the guide frame 815, then smoothly enters into the downward pressure guide frame 812, and slides along the internal contour of the downward pressure guide frame 812. During this period, the guide rod 811 drives the pull-down rod 807 and the vacuum plate 803 to move downward, so that the rubber suction cup 806 can be more tightly adsorbed on the piston.

[0116] When the lower pull rod 807 moves downward, the driving block 907 moves along with it, and the power rack 901 moves a certain distance inward. Under the connection of the first connecting gear 902 and the second connecting gear 903, the driving rack 905 drives the contact rod 906 to move outward. The contact rod 906 will gradually contact the inner wall of the piston to clamp the piston internally.

[0117] During this process, the driving gear 702 will gradually mesh with the fixed rack 701. Under the connection between the second bevel gear 703 and the first bevel gear 705, the placement cylinder 6 will drive the piston on its upper side to rotate slowly, thereby improving the uniformity of heating of the piston during heat treatment.

[0118] When the transmission chain 2 drives the receiving plate 3 to move downward, the placement tube 6 is in an inverted state. Under the combined action of gravity and magnetic force, the cleaning rod 507 enters the rubber suction cup 806 to push out the metal debris, and the magnet 506 will absorb the metal debris.

[0119] During the rotation of the sprocket 4 , under the connection between the driving wheel 505 and the belt 501 , the magnet 506 will continue to rotate, and the scraper 503 will scrape the debris absorbed on its surface into the collection box 502 .
