Description

Technical Field

[0001] This utility model relates to a quenching device, and more particularly, to a quenching device for motor shaft accessories. Background Technology

[0002] Currently, Chinese patent CN217297947U discloses a quenching furnace, including a furnace body, a door installed at the front end of the furnace body, an electric lock installed on one side of the rear end of the door, and a locking hook for connecting the electric lock installed on one side of the front end of the furnace body.

[0003] The aforementioned patent still has shortcomings. The aforementioned quenching furnace can only place individual products to be quenched inside the furnace, or place multiple products at intervals. The placement method is relatively simple and is only suitable for placing larger products. When processing a large number of small motor shaft accessories, especially shaft parts, the products are prone to rolling and stacking, affecting the quenching effect. At the same time, the space utilization rate inside the quenching furnace is poor, affecting the quenching efficiency. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a quenching device for motor shaft accessories, which has the advantage of high quenching efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: a quenching device for motor shaft accessories, including a furnace body, a switch door is provided on one side of the furnace body, and a product rack is also provided. Mounting racks are provided on both the left and right sides of the furnace body. Several rack slots are opened on the two mounting racks. The product rack is installed in two corresponding rack slots. The product rack is used to place motor shaft accessories. A radiant tube for heating the motor shaft accessories is also provided in the rack slot. The radiant tube is arranged laterally along the rack slot direction.

[0006] Preferably, the furnace also includes a second product rack, and a top frame is provided inside the furnace body. A sliding groove is provided in the middle of the top frame, and a sliding block assembly that cooperates with the sliding groove is provided on the top of the second product rack.

[0007] Preferably, the product frame includes a central rod and a plurality of mounting plates arranged in a linear array on the central rod. The mounting plates are provided with a plurality of mounting holes for mounting motor shaft accessories. The sliding block assembly is located at the top of the central rod.

[0008] Preferably, the sliding groove is T-shaped, and the sliding block assembly includes a T-shaped slider and pulleys. The pulleys are disposed on both sides of the T-shaped slider and make rolling contact with the inner sidewall of the sliding groove.

[0009] Preferably, a mounting plate is also provided between the top frame and the sliding block assembly.

[0010] Preferably, the product rack includes a side slide and a mesh plate, and a roller assembly is also provided at the bottom of the rack groove, with the side slide slidingly mounted on the roller assembly.

[0011] Preferably, a protective plate is also provided inside the rack groove, and the radiant tube is fixedly installed on the upper end of the protective plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By cooperating between product rack one and rack slot, and between product rack two and sliding slot, products are prevented from being stacked in the furnace, thus increasing the quenching effect. At the same time, the products are fixed in two ways to ensure the installation and placement of disc-shaped and shaft-shaped parts. 2. By installing pulleys on both sides of the T-shaped slider, it is ensured that the product rack 2 is not prone to jamming when placed and taken out, and at the same time, the product rack 2 will not wobble significantly from side to side, increasing the stability during loading and unloading. 3. By installing roller sets at the bottom of the rack slot, it is ensured that the product rack will not experience excessive friction between the side slide and the mounting frame due to the weight of the product, thus preventing jamming.

[0015] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, so that the technical solution of this utility model can be more easily understood and mastered. Example 1:

[0016] A quenching device for motor shaft accessories includes a furnace body 1, which is horizontally placed. A switch door 2 is provided on one side of the furnace body 1. The switch door 2 is closed and locked by bolts, spring locks, etc. The device also includes a product rack 3. Mounting racks 4 are provided on both the left and right sides of the furnace body 1. Several rack slots 5 are provided on the two mounting racks 4. The product rack 3 is installed in the corresponding two rack slots 5. The product rack 3 is used to place disc-shaped parts in the motor shaft accessories. When the quenching furnace is a large furnace, the product rack 3 can be sent into the furnace body 1 by loading equipment such as forklifts. Radiation tubes 6 for heating motor shaft accessories are also provided in the rack slots 5. The radiation tubes 6 are arranged laterally along the direction of the rack slots 5.

[0017] A protective plate 7 is also installed inside the rack slot 5. The radiant tube 6 is fixedly installed on the upper end of the protective plate 7, and the product rack 3 is installed on the bottom side of the protective plate 7, so as to ensure that the product rack 3 will not touch the radiant tube 6 during the feeding process and reduce the possibility of damage to the radiant tube 6. Example 2:

[0018] The difference between Embodiment 2 and Embodiment 1 is that the product rack 3 includes a side sliding frame 8 and a mesh plate 9. A roller group 10 is also provided at the bottom of the rack groove 5. The side sliding frame 8 is slidably mounted on the roller group 10. When the quenching furnace is a small furnace and the product rack needs to be placed manually, the roller group 10 is set to reduce the friction between the side sliding frame 8 and the rack groove 5, so that the product rack 3 will not experience jamming due to the large friction between the side sliding frame 8 and the mounting frame 4 when the product is placed and taken out. Example 3:

[0019] The difference between Embodiment 3 and Embodiment 1 is that Embodiment 3 also includes a second product rack 11, and a top rack 12 is provided inside the furnace body 1. A sliding groove 13 is provided in the middle of the top rack 12. A sliding block assembly 14 that cooperates with the sliding groove 13 is provided on the top of the second product rack 11. The second product rack 11 is installed inside the furnace body 1 by hoisting. By setting the structure of the second product rack 11, the space utilization rate inside the furnace can be relatively increased.

[0020] Product rack 2 11 includes a central rod 15 and several mounting plates 16. The mounting plates 16 are arranged in a linear array on the central rod 15. Several mounting holes 17 are opened on the mounting plates 16 for mounting shaft accessories. The sliding block assembly 14 is located on the top of the central rod 15. The sliding groove 13 is T-shaped. The sliding block assembly 14 includes a T-shaped slider 18 and pulleys 19. The pulleys 19 are located on both sides of the T-shaped slider 18 and roll in contact with the inner sidewall of the sliding groove 13 to ensure that product rack 2 11 is not prone to jamming when placed and removed. At the same time, it prevents product rack 2 11 from swaying significantly from side to side, increasing the stability during loading and unloading. An insert plate 20 is also provided between the top frame 12 and the sliding block assembly 14 to facilitate forklifts and other loading equipment to support the insert plate 20 and send product rack 2 11 into the furnace.

[0021] Of course, the above are just typical examples of this utility model. In addition, this utility model may have many other specific implementation methods. All technical solutions formed by equivalent substitution or equivalent transformation fall within the scope of protection claimed by this utility model.
