Technical Field
[0001] This utility model relates to the field of tool magazine housings, and in particular to a fully sealed sheet metal housing for chain-type tool magazines. Background Technology
[0002] Chain-type tool magazines are a type of tool magazine used in CNC machine tools. They have a large tool capacity but low tool magazine positioning accuracy. A chain-type tool magazine consists of an outer shell, a drive sprocket, a chain, a tool holder, a positioning plate, and a transmission device. The main function of the outer shell is to protect the internal mechanical structure and tools.
[0003] While existing tool magazine housings provide necessary support and guidance for the internal structure, they also present other problems during use, such as poor dust and chip protection. The open design of the front of the housing allows tools and tool holders to be exposed to the air after installation, making them prone to dust accumulation. Debris splashed during product processing can also easily enter, increasing the maintenance burden on personnel. Moreover, the external protection is poor; when the housing is subjected to collisions and impacts from external objects, it cannot buffer the force of the impact. Excessive impact force can cause the housing to dent and deform inward, affecting the normal rotation of the internal structure and resulting in low safety. To solve the above problems, we propose a fully sealed sheet metal housing for chain-type tool magazines. Utility Model Content
[0004] The purpose of this invention is to provide a fully sealed sheet metal housing for chain-type tool magazines, which solves the problems of poor dust and chip prevention and poor external protection of existing sheet metal housings.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a fully sealed sheet metal shell for a chain-type tool magazine, comprising a shell, a fixed cylinder installed inside the shell, a screw rotatably connected inside the fixed cylinder, a motor fixedly sleeved at the other end of the screw, a threaded plate threadedly connected to the surface of the screw, a movable plate and a baffle respectively provided on the other side and surface of the fixed cylinder, a support rod installed between one side of the movable plate and the baffle, a connecting rod installed between one side of the threaded plate and the movable plate, protective plates equidistantly arranged on the surface of the shell, fixed rods symmetrically installed inside the protective plates, a connecting block bolted to the other side of the fixed rod, a fixing seat bolted to the shell on the surface of the connecting block, and a buffer spring installed between the bottom of the connecting block and the fixing seat.
[0006] The above technical solution can provide a sealing function at the opening, which can prevent debris and dust generated during product processing from entering, reduce the maintenance burden on personnel, provide good flexibility, improve the external protective buffering effect, reduce the damage and impact caused by impact, extend the service life of the shell, and has high practicality.
[0007] The present invention is further configured such that the surfaces of the shell, the fixing cylinder and the baffle are all coated with anti-corrosion coating.
[0008] By adopting the above technical solution and applying anti-corrosion coatings, the anti-corrosion and moisture-proof effects of the shell, fixed cylinder and baffle surfaces can be improved.
[0009] The present invention is further configured such that a stop block is fixedly sleeved on the surface of the fixed cylinder.
[0010] By adopting the above technical solution, the sealing effect between the housing and the baffle can be improved by setting the baffle, and dust can be prevented from entering through the opening inside the baffle.
[0011] The present invention is further configured such that: a guide rod is installed on one side of the connecting block, a sliding groove is provided on one side of the fixing seat, and the other end of the guide rod extends to the outside of the sliding groove.
[0012] By adopting the above technical solution, the connecting block can be limited by the guide rod and sliding groove to prevent it from tilting when it moves inward under pressure.
[0013] The present invention is further configured such that a damper is installed between the bottom of the connecting block and the fixed seat.
[0014] By adopting the above technical solution, the damper can be used to suppress the bounce of the buffer spring and consume the kinetic energy stored in the buffer spring, thereby reducing the resonance amplitude and improving stability.
[0015] The present invention is further configured such that a rubber pad is adhered to the surface of the protective plate.
[0016] By adopting the above technical solution and setting up rubber pads, damage caused by impacts from external objects can be reduced.
[0017] The present invention is further configured such that the buffer spring is made of carbon spring steel.
[0018] Using the above technical solution, the buffer spring has the characteristics of excellent mechanical properties, good anti-elasticity, low temperature resistance and corrosion resistance.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. This utility model enables the motor to be started when it needs to be opened. After the motor starts, it will drive the screw to rotate. When the screw rotates, it will drive the threaded plate and the connecting rod to move outward. When the connecting rod moves outward, it will drive the moving plate to move outward together. When the moving plate moves outward, it will drive the baffle to move outward and separate from the shell under the fixation of the support rod. It can provide a sealing function at the opening, which can prevent the entry of debris and dust generated during product processing, reduce the maintenance burden of personnel, and has good flexibility.
[0021] 2. This utility model utilizes the principle that when the rubber pad is impacted, the protective plate moves inward. As the protective plate moves inward, the connecting block moves into the fixed seat under the fixation of the fixing rod. When the connecting block moves, it compresses the buffer spring and damper, causing them to contract. When the buffer spring contracts, it absorbs and cancels out the force energy, thereby improving the external protective buffering effect, reducing the damage and impact caused by the impact, and extending the service life of the shell. It is highly practical. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings.
[0028] Example 1:
[0029] refer to Figure 1 , Figure 2 and Figure 3A fully sealed sheet metal housing for a chain-type tool magazine includes a housing 1. A fixed cylinder 2 is installed inside the housing 1. A screw 3 is rotatably connected inside the fixed cylinder 2. A motor 4 is fixedly sleeved at the other end of the screw 3. A threaded plate 5 is threadedly connected to the surface of the screw 3. A movable plate 6 and a baffle 7 are respectively provided on the other side and surface of the fixed cylinder 2. A support rod 8 is installed between one side of the movable plate 6 and the baffle 7. A connecting rod is installed between one side of the threaded plate 5 and the movable plate 6. When it is necessary to open, the motor 4 is started. After the motor 4 starts, it drives the screw 3 to rotate. When the screw 3 rotates, it drives the threaded plate 5 and the connecting rod to move outward. When the connecting rod moves outward, it drives the movable plate 6 to move outward together. When the movable plate 6 moves outward, it drives the baffle 7 to move outward and separate from the housing 1 under the fixation of the support rod 8. It can provide a sealing function at the opening, which can prevent the entry of debris and dust generated during product processing, reduce the maintenance burden of personnel, and has good flexibility.
[0030] refer to Figure 1 , Figure 2 and Figure 3 The surfaces of the housing 1, the fixed cylinder 2, and the baffle 7 are all coated with anti-corrosion paint. The anti-corrosion and moisture-proof effects of the surfaces of the housing 1, the fixed cylinder 2, and the baffle 7 can be improved by the application of anti-corrosion paint.
[0031] refer to Figure 2 A stop 14 is fixedly sleeved on the surface of the fixed cylinder 2. The stop 14 can improve the sealing effect between the housing 1 and the baffle 7 and prevent dust from entering from the opening inside the baffle 7.
[0032] Brief description of the usage process: When it is necessary to open, the motor 4 is started. After the motor 4 is started, it will drive the screw 3 to rotate. When the screw 3 rotates, it will drive the threaded plate 5 and the connecting rod to move outward. When the connecting rod moves outward, it will drive the moving plate 6 to move outward together. When the moving plate 6 moves outward, it will drive the baffle 7 to move outward and separate from the housing 1 under the fixation of the support rod 8.
[0033] Example 2:
[0034] refer to Figure 1 , Figure 2 , Figure 3 and Figure 4A fully sealed sheet metal housing for a chain-type tool magazine is disclosed. Protective plates 9 are equidistantly arranged on the surface of the housing 1. Fixing rods 10 are symmetrically installed inside the protective plates 9. A connecting block 11 is bolted to the other side of the fixing rod 10. A fixing seat 12, bolted to the housing 1, is provided on the surface of the connecting block 11. A buffer spring 13 is installed between the bottom of the connecting block 11 and the fixing seat 12. When the rubber pad 17 is impacted, the protective plates 9 move inward. As the protective plates 9 move inward, the fixing rods 10 cause the connecting block 11 to move inward into the fixing seat 12. During this movement, the connecting block 11 compresses the buffer spring 13 and the damper 16, causing them to contract. The contracted buffer spring 13 absorbs and cancels out the force, improving the external protective buffering effect, reducing damage and impact from impacts, extending the service life of the housing 1, and demonstrating high practicality.
[0035] refer to Figure 3 and Figure 4 A guide rod 15 is installed on one side of the connecting block 11, and a sliding groove is provided on one side of the fixed seat 12. The other end of the guide rod 15 extends to the outside of the sliding groove. Through the setting of the guide rod 15 and the sliding groove, the connecting block 11 can be limited to prevent it from tilting when it is pressed inward.
[0036] refer to Figure 4 A damper 16 is installed between the bottom of the connecting block 11 and the fixed base 12. The damper 16 can suppress the jumping of the buffer spring 13 and consume the kinetic energy stored in the buffer spring 13, thereby reducing the resonance amplitude and improving stability.
[0037] refer to Figure 1 and Figure 3 The surface of the protective plate 9 is bonded with a rubber pad 17. The rubber pad 17 can reduce the damage caused by the impact of external objects.
[0038] refer to Figure 4 The buffer spring 13 is made of carbon spring steel and has excellent mechanical properties, good spring damping performance, low temperature resistance and corrosion resistance.
[0039] Brief description of the usage process: When the rubber pad 17 is impacted, the protective plate 9 will move inward. When the protective plate 9 moves inward, it will drive the connecting block 11 to move into the fixed seat 12 under the fixation of the fixing rod 10. When the connecting block 11 moves, it will compress the buffer spring 13 and the damper 16, causing them to contract. When the buffer spring 13 contracts, it will absorb and cancel the force.
