Description

Technical Field

[0001] This utility model relates to the field of camshaft processing technology, specifically to an automatic feeding camshaft heat treatment device. Background Technology

[0002] The camshaft is a component in a piston engine. Its function is to control the opening and closing of the valves. The camshaft is mainly composed of a shaft body, journals, and cams. After the operator finishes machining the camshaft using a machine tool, the cams on the camshaft usually need to be hardened to strengthen the cams.

[0003] Utility model patent CN219637285U discloses a camshaft heat treatment device. This utility model includes a water tank base, a lead screw lifting device, a quenching device, a cooling device, and a demisting system. The water tank base and cooling device are an integral structure. The cooling device is located on one side of the water tank base, and the lead screw lifting device is located on the other side. The demisting system is located between the cooling device and the water tank base. The quenching device is located on the outside of the water tank base, with its quenching end located between the cooling device and the lead screw lifting device. The lead screw lifting device is equipped with a clamping mechanism located below the quenching end of the quenching device. This utility model effectively solves the problem of high-temperature water vapor during quenching and cooling by setting up a demisting system. By separately setting up heating coils, it solves the problem of inconsistent heating depth between the camshaft groove and the shaft diameter and improves the quenching speed.

[0004] While the aforementioned invention can solve the problem of inconsistent heating depths in the camshaft groove and shaft diameter, its use requires manual or hand-held tools to place the camshaft into the clamping mechanism within the heat treatment device. Manual loading of the camshaft cannot guarantee it will remain vertical; if the camshaft is fixed at an angle, it will affect the heat treatment process. Therefore, we propose an automatic feeding camshaft heat treatment device. Utility Model Content

[0005] This invention provides an automatic feeding camshaft heat treatment device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An automatic feeding camshaft heat treatment device includes a heat treatment device body, and a feeding mechanism is provided on the rear side of the heat treatment device body. The feeding mechanism includes a support column welded to the rear surface of the heat treatment device body and a feeding box welded to the top of the support column.

[0008] The feeding box includes a box body, a lifting mechanism installed inside the rear side of the box body, a clamping mechanism welded to the outside of the lifting mechanism, and a negative pressure pump installed on the top of the box body.

[0009] As a preferred technical solution, the height of the support column is greater than the height of the heating coil in the body of the heat treatment device, and the top of the box is located below the support plate in the body of the heat treatment device.

[0010] This feature ensures that the camshaft fed from the feed box can smoothly enter the inner heating coil of the heat treatment unit body, ensuring that the movement of the camshaft is not blocked by the heating coil.

[0011] As a preferred technical solution, the front surface of the box body is provided with an opening, the front side of the inner bottom wall of the box body is provided with an auxiliary hole, the rear side of the inner bottom wall of the box body is provided with a through hole, and the front side of the top of the box body is provided with an auxiliary groove.

[0012] This setting ensures that the bottom of the inserted camshaft can be inserted into the through hole and remain vertical until it is attracted and clamped by the clamping mechanism.

[0013] As a preferred technical solution, the lifting mechanism includes a lifting threaded rod rotatably connected to the rear side of the inner top wall of the box and a lifting block threadedly connected to the outside of the lifting threaded rod. A motor for controlling the rotation of the lifting threaded rod is installed at the bottom of the outer side of the box.

[0014] As a preferred technical solution, the bottom of the lifting threaded rod rotates through the through hole and is coaxially connected to the motor output shaft, and the width of the lifting block is equal to the internal width of the box.

[0015] These two settings ensure that the lifting block can move vertically on the lifting threaded rod as it rotates, thereby driving the clamping mechanism to move vertically.

[0016] As a preferred technical solution, the clamping mechanism includes an electric push rod installed on the front surface of the lifting block, a connecting block welded to the extension rod of the electric push rod, and an insert block inserted into the front end of the connecting block. A clamping block is welded inside the front end of the insert block, and a plurality of adsorption holes are opened on the inner surface of the front end of the clamping block. A connecting pipe is connected to the top of the clamping block, and a limit bolt is threadedly connected to the top of the connecting block. The bottom of the limit bolt can be threaded into the rear top of the insert block.

[0017] As a preferred technical solution, the front surface of the connecting block is provided with a slot for the insertion block to be inserted, the rear end of the insertion block (2234) is inserted into the slot, and the rear top of the insertion block is provided with a threaded hole for the bottom threaded connection of the limiting bolt.

[0018] As a preferred technical solution, the end of the connecting pipe away from the clamping block is connected to the negative pressure pump, the clamping block has a C-shaped structure in its top view, and the clamping block is a hollow structure.

[0019] These three settings ensure that the clamping mechanism can adhere to the side surface of the camshaft to adsorb and clamp the camshaft. Depending on the size of the camshaft, the clamping block can also be disassembled and replaced to ensure that the inner surface of the clamping block can adhere to the side surface of the camshaft to complete the adsorption and clamping of the camshaft.

[0020] Compared with the prior art, the beneficial effects of this utility model are:

[0021] 1. This utility model uses a negative pressure pump to enable the clamping mechanism to adsorb and fix the camshaft on the inner surface of the clamping block. Then, the camshaft is sent into the body of the heat treatment device by an electric push rod, which can ensure that the camshaft sent into the body of the heat treatment device is always in a vertical state until it is fixed by the pressing device inside the body of the heat treatment device.

[0022] 2. In this utility model, after the clamping mechanism delivers the camshaft to a suitable position and fixes it, the clamping mechanism can easily release the camshaft and remove it from the heat treatment device body area, preventing it from affecting the heat treatment device body's heat treatment of the camshaft.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Please see Figures 1-6 This embodiment provides a technical solution:

[0033] An automatic feeding camshaft heat treatment device includes a heat treatment device body 100, a feeding mechanism 200 is provided on the rear side of the heat treatment device body 100, and the feeding mechanism 200 includes a support column 210 welded to the rear surface of the heat treatment device body 100 and a feeding box 220 welded to the top of the support column 210.

[0034] The loading box 220 includes a box body 221, a lifting mechanism 222 installed inside the rear side of the box body 221, a clamping mechanism 223 welded to the outside of the lifting mechanism 222, and a negative pressure pump 224 installed on the top of the box body 221. Through the above mechanism, the camshaft to be processed can be placed in the box body 221 and wait for the clamping mechanism 223 and the lifting mechanism 222 to cooperate in sending it into the heat treatment apparatus body 100.

[0035] Furthermore, such as Figure 1 As shown, the height of the support column 210 is greater than the height of the heating coil in the heat treatment device body 100, and the top of the box 221 is located below the support plate in the heat treatment device body 100, ensuring that the camshaft will not be blocked by the heating coil when it enters the heat treatment device body 100.

[0036] Furthermore, such as Figure 4As shown, the front surface of the box 221 has an opening, the front side of the inner bottom wall of the box 221 has an auxiliary hole 2211, the rear side of the inner bottom wall of the box 221 has a through hole 2212, and the front side of the top of the box 221 has an auxiliary groove 2213. The auxiliary hole 2211 facilitates the insertion and placement of the camshaft, and the auxiliary groove 2213 facilitates the user to place the camshaft into the auxiliary hole 2211.

[0037] In this embodiment, as Figure 5 As shown, the lifting mechanism 222 includes a lifting threaded rod 2222 rotatably connected to the rear side of the inner top wall of the box 221 and a lifting block 2223 threadedly connected to the outer side of the lifting threaded rod 2222. A motor 2221 for controlling the rotation of the lifting threaded rod 2222 is installed at the bottom of the outer side of the box 221. The bottom of the lifting threaded rod 2222 rotates through the through hole 2212 and is coaxially connected to the output shaft of the motor 2221. The width of the lifting block 2223 is equal to the inner width of the box 221, so that the outer wall of the lifting block 2223 slides against the inner wall of the box 221, thereby ensuring that when the lifting threaded rod 2222 rotates, the lifting block 2223 will move vertically with the rotation.

[0038] In this embodiment, as Figure 6 As shown, the clamping mechanism 223 includes an electric push rod 2231 mounted on the front surface of the lifting block 2223, a connecting block 2232 welded to the extension rod of the electric push rod 2231, and an insert block 2234 inserted into the front end of the connecting block 2232. A clamping block 2235 is welded to the front end of the insert block 2234. Several adsorption holes 2236 are opened on the inner surface of the front end of the clamping block 2235. A connecting pipe 2237 is connected to the top of the clamping block 2235. A limiting bolt 2233 is threadedly connected to the top of the connecting block 2232. The bottom of the limiting bolt 2233 can be threaded into the rear top of the insert block 2234, thereby fixing the rear end of the insert block 2234 in the connecting block 2232 by the limiting bolt 2233.

[0039] In this embodiment, as Figure 6 As shown, the front surface of the connecting block 2232 has a slot for the insertion block 2234. The rear end of the insertion block 2234 is inserted into the slot. The top rear side of the insertion block 2234 has a threaded hole for the bottom threaded connection of the limiting bolt 2233. The threaded hole ensures that the bottom of the limiting bolt 2233 can be threaded into the insertion block 2234. The end of the connecting pipe 2237 away from the clamping block 2235 is connected to the negative pressure pump 224. The clamping block 2235 has a C-shaped structure in its top view. The clamping block 2235 is a hollow structure, and the adsorption hole 2236 communicates with the interior of the clamping block 2235. The C-shaped clamping block 2235 can more easily fit the side surface of the camshaft.

[0040] It is worth noting that the structure and working principle of the motor 2221, electric push rod 2231, and negative pressure pump 224 involved in this embodiment are as known to those skilled in the art, and will not be described in detail here. The structure and working principle of the heat treatment device body 100, heating coil, and support plate involved in this embodiment are all technologies disclosed in the prior art, and will not be described in detail here.

[0041] In this embodiment, the automatic feeding camshaft heat treatment device is used as follows: First, the camshaft is placed through the auxiliary groove 2213 into the auxiliary hole 2211 in the housing 221. Then, the motor 2221 is started to control the rotation of the lifting threaded rod 2222, allowing the lifting block 2223 to move vertically along the lifting threaded rod 2222. When the lifting block 2223 moves the clamping mechanism 223 to a suitable height, i.e., the inner surface of the clamping block 2235 can smoothly fit against the side surface of the camshaft, the motor 2221 is turned off. Then, the electric push rod 2231 is started until the inner surface of the clamping block 2235 fits against the side surface of the camshaft, the extension of the electric push rod 2231 is stopped, and the negative pressure pump 224 is started. Through the connecting pipe 2237, a negative pressure zone is formed in the area of ​​the adsorption hole 2236 to heat the camshaft. After the clamping block 2235 is clamped to the camshaft, the motor 2221 is started to control the lifting block 2223 to move upward a certain distance through the lifting threaded rod 2222 until the bottom of the camshaft leaves the through hole 2212. Then, the motor is started again and the electric push rod 2231 is extended to the farthest end so that the camshaft can enter a suitable position inside the heat treatment device body 100. Then, the motor 2221 controls the lifting threaded rod 2222 to rotate, so that the lifting block 2223 descends. This causes the clamping mechanism 223 to descend with the clamped camshaft into a suitable position in the heat treatment device body 100 until it is fixed by the clamping device inside the heat treatment device body. The heat treatment device body 100 then performs heat treatment. After that, the negative pressure pump 224 is turned off, and the clamping mechanism 223 and the lifting mechanism 222 are returned to their original positions.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
