Obviously, the described implementation is only a part of the implementation of the utility model, not all of the implementations. Based on the implementation of the utility model, all other implementations obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] like Figure 1-3 As shown, the workpiece transfer device for a thermal cleaning furnace of the utility model comprises a base 1, a turntable 2, a slide rail assembly 3 and a transfer trolley 4.

[0032] The base 1 is embedded in the ground. A foundation pit needs to be preset on the equipment foundation on the ground. The base 1 is embedded in the ground through the foundation pit to avoid a large height difference between the top of the base 1 and the ground, which makes it difficult for the subsequent transfer cart 4 to move to the top of the base 1. In addition, in order to ensure that the base 1 has better stability, the base 1 can be fixed to the equipment foundation by expansion screws, embedded bolts or partially embedded installation methods, so that it has better bearing performance. At the same time, the base 1 is made of steel structure as a whole.

[0033] The turntable 2 is rotatably arranged on the base 1. Specifically, a bearing is arranged on the base 1. The inner and outer sides of the bearing are respectively fixed to the base 1 and the turntable 2 by bolts, so that the turntable 2 can rotate on the base 1 through the bearing. The rotation of the turntable 2 needs to be on a horizontal plane, and its top needs to be parallel to the horizontal plane to avoid sliding under the influence of the gravity component after the transfer cart 4 is moved onto the turntable 2.

[0034] In addition, the base 1 and the turntable 2 are both arranged in a foundation pit. In order to prevent the rotation of the turntable 2 from being hindered by the foundation pit, the diagonal length of the turntable 2 needs to be smaller than the minimum width of the foundation pit.

[0035] The slide rail assembly 3 is arranged on the turntable 2 and can rotate together with the turntable 2. The slide rail assembly 3 includes a docking end 301, and the docking end 301 is movably arranged on the turntable 2. The docking end 301 is used to be set up on the ground and in the hot cleaning furnace.

[0036] Specifically, the slide rail assembly 3 is fixed on the top of the turntable 2, and the butt end 301 of the slide rail assembly 3 extends out of the turntable 2 and extends to the side of the turntable 2 to avoid obstruction caused by the movement of the butt end 301 of the turntable 2. The slide rail assembly 3 is a linear track so that the transfer trolley 4 can slide linearly on the turntable 2.

[0037] The transfer trolley 4 is arranged opposite to the base 1, and the wheels of the transfer trolley 4 are adapted to the slide rail assembly 3 so that the transfer trolley 4 can move to the turntable 2 and the thermal cleaning furnace through the docking end 301. The transfer trolley 4 is used to transfer workpieces. It should be noted that the size of the turntable 2 needs to be larger than the size of the transfer trolley 4.

[0038] In this process, the transfer trolley 4 is loaded with workpieces and moves on the ground. The docking end 301 of the slide rail assembly 3 is placed on the ground. The transfer trolley 4 moves to the turntable 2 through the docking end 301, and the docking end 301 is retracted. The turntable 2 rotates to align the slide rail assembly 3 with the thermal cleaning furnace, and puts the docking end 301 into the thermal cleaning furnace, thereby pushing the transfer trolley 4 into the thermal cleaning furnace. When the workpieces in the thermal cleaning furnace are processed, the thermal cleaning furnace door is opened, and the docking end 301 is put into the thermal cleaning furnace again. The transfer trolley 4 is pushed onto the turntable 2, and the turntable 2 is rotated. The other side of the turntable 2 can be directly docked with the next process equipment, so that the transfer trolley 4 directly enters the next process, and at the same time, the next transfer trolley 4 loaded with the workpiece to be cleaned is pushed onto the turntable 2, and the above operations are repeated, thereby continuously processing the workpieces in a cycle.

[0039] In this embodiment, the transfer vehicle 4 includes a base 41 and a hanger 42. The base 41 is arranged opposite to the turntable 2, and wheels are arranged on the base 41. The hanger 42 is fixed on the base 41, and the hanger 42 is used to hang the workpiece.

[0040] The base 41 is a stainless steel frame, and the bracket 42 is shaped and sized according to the required processing components. The workpiece is mounted on the bracket 42 and then moved by the base 41. The base 41 is provided with four wheels, at least two of which are universal wheels, and the spacing between the four wheels is adapted to the slide rail assembly 3.

[0041] As a preferred embodiment, a mounting surface 201 is provided on the turntable 2, and the slide rail assembly 3 is arranged on the mounting surface 201. The mounting surface 201 and the ground on which the base 1 is set are located on the same horizontal plane. The mounting surface 201 is the top surface of the turntable 2. For the special-shaped setting of the turntable 2, the mounting surface 201 is the plane on which the slide rail assembly 3 is installed.

[0042] This arrangement allows the transfer cart 4 to move unhindered to the turntable 2 via the guide rail assembly when the docking end 301 is docked to the ground, thereby reducing the difficulty of operation and improving the transfer efficiency.

[0043] In this embodiment, the slide rail assembly 3 also includes a fixed rail 31 , which is fixed on the turntable 2 , and a docking end 301 is arranged at the end of the fixed rail 31 , and the fixed rail 31 is used to enable the transfer trolley 4 to move on the turntable 2 .

[0044] Specifically, there are two fixed rails 31, and both are arranged on the mounting surface 201. At the same time, the two fixed rails 31 are parallel to each other, and the spacing between the two fixed rails 31 is adapted to the spacing between the wheels of the transfer cart 4, so that the transfer cart 4 can move on the turntable 2 through the two fixed rails 31. In addition, the length of the fixed rail 31 is at least greater than the length of one transfer cart 4. If there is a demand for the number of carts to be parked, the fixed rail 31 can be extended according to the demand.

[0045] In addition, the slide rail assembly 3 further includes a movable rail 32 , which is movably disposed at the end of the fixed rail 31 , and the docking end 301 is disposed on the movable rail 32 .

[0046] The docking end 301 is the end of the movable rail 32 away from the fixed rail 31. Similar to the fixed rail 31, on one side of the turntable 2, the number of movable rails 32 is set to two, so that the transfer trolley 4 can move through the two movable rails 32. A cross bar is welded between the two movable rails 32, through which the two movable rails 32 can move synchronously to avoid separately retracting and extending the two movable rails 32 during operation.

[0047] In this embodiment, the slide rail assembly 3 further includes an articulated seat 33 , which is disposed on the fixed rail 31 , so that the fixed rail 31 is articulated with the movable rail 32 through the articulated seat 33 .

[0048] The movable rail 32 can be rotated and folded onto the fixed rail 31 through the hinge seat 33, and can also be rotated to dock with the ground, the heat cleaning furnace or the equipment of the next process. It should be noted that the movable rail 32 needs to be rotated upward during the folding process to avoid being blocked by other parts and unable to rotate.

[0049] As a preferred embodiment, the number of the docking ends 301 is two, and they are symmetrically arranged on both sides of the turntable 2. After the docking ends 301 are set to two and symmetrically on both sides of the turntable 2, the corresponding number of movable rails 32 is set to four, and they are located on both sides of the turntable 2 in groups of two. This arrangement allows the transfer cart 4 to go down from one side of the turntable 2 and up from the other side, so that the movement of the transfer carts 4 on both sides does not interfere with each other, thereby avoiding affecting the transfer efficiency during operation.

[0050] In this embodiment, the base 1 includes a base body 11 and a support frame 12 . The base body 11 is fixed to the ground. The turntable 2 is disposed on the base body 11 . The support frame 12 is fixed on the base body 11 . The support frame 12 is used to support the turntable 2 .

[0051] The seat body 11 is the main part of the base 1, which mainly connects to the ground and supports the turntable 2. The bearing on the base 1 is arranged on the seat body 11, and the support frame 12 is arranged to increase the supporting area of ​​the seat body 11 for the turntable 2 to avoid forming a long force arm and affecting the structural stability. Specifically, the support frame 12 is a polygonal frame and is welded to the outside of the seat body 11 with the bearing as the center.

[0052] In addition, in the present embodiment, a plurality of ball seats 5 are provided. The plurality of ball seats 5 are all provided on the support frame 12 and are distributed in a ring shape. The ball seats 5 are in rolling contact with the turntable 2 .

[0053] A ball is arranged on each ball seat 5, and the ball contacts the bottom of the turntable 2, thereby forming a stable support for the bottom of the turntable 2 to avoid forming an excessively long force arm.

[0054] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
