Description

Technical Field

[0001] The utility model relates to the technical field of filter processing, in particular to a fixing tool for filter maintenance and repair. Background Art

[0002] A filter is a component that filters impurities or gases through a filter paper. Generally, it refers to an automotive filter, which is a component of an engine. There are three types of filters for an engine: air filter, oil filter, and fuel filter, generally referred to as "three filters", plus an air-conditioning filter, commonly known as "four filters". They are respectively responsible for filtering in the lubrication system, the medium in the combustion system, the engine intake system, and the cabin air circulation system.

[0003] When there are defective products in the filter processing process, the defective products need to be repaired to improve the yield rate or realize the recycling and reuse of components. Currently, the fixing tool used in the filter maintenance process is a bench vice, and there are the following deficiencies in the actual use of clamping the filter with a bench vice: the entire clamping process requires manual participation of the operator. On the one hand, it increases the workload and difficulty of the actual operation of the operator. On the other hand, the operator needs to manually control the clamping force exerted by the fixture on the filter. When the clamping force is too large, it is easy to cause problems such as clamping marks or deformation on the filter housing. When the clamping force is too small, it is easy to cause problems such as displacement and falling off during the filter maintenance process.

[0004] In view of this, it is particularly important to design and manufacture a fixing tool that can realize automatic and stable clamping of filters and reduce the occurrence of abnormal fixing problems during the filter maintenance process. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a fixing tool for filter maintenance and repair, aiming to solve the problems that the traditional fixing tool used for filter maintenance has poor operation convenience, low efficiency, and is prone to abnormal fixing during use.

[0006] To achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A fixing tool for filter maintenance and repair includes a fixing table. The lower end of the fixing table is rotationally installed with a U-shaped frame through a rotary lock part. A material placing hole is opened in the middle of the fixing table. The middle part of the lower end of the fixing table is fixedly connected with a material supporting frame below the material placing hole. A clamping mechanism for automatically and inductively clamping the filter after it is placed is arranged on the fixing table.

[0008] As a further description of the above technical solution:

[0009] The clamping mechanism includes three mounting seats fixed at 120° intervals at the lower end of the fixed table and outside the material discharge hole, an electric oil cylinder mounted outside the three mounting seats, a rubber clamping block mounted at the inner end of the electric oil cylinder, a pressure sensor mounted between the inner end of the electric oil cylinder and the rubber clamping block, and a controller arranged at the upper end of the fixed table for receiving and processing the pressure data of the pressure sensor.

[0010] As a further description of the above technical solution:

[0011] A display screen is mounted on the left side of the front end of the controller, a control switch is mounted above the right side of the front end of the controller, and a buzzer is mounted below the control switch at the front end of the controller.

[0012] As a further description of the above technical solution:

[0013] The output ends of the pressure sensor and the control switch are electrically connected to the input end of the controller, and the output end of the controller is electrically connected to the input ends of the display screen and the buzzer respectively.

[0014] As a further description of the above technical solution:

[0015] The rotary lock part includes a gear disk fixed at the right end of the fixed table and fitting against the outer wall of the U-shaped frame, a limit sliding groove opened at the right end of the U-shaped frame and below the gear disk, a sliding lock block movably installed inside the limit sliding groove, and a lock tooth fixed at the upper end of the sliding lock block and meshing with the gear disk.

[0016] As a further description of the above technical solution:

[0017] A handle is integrally and fixedly connected to the outer end of the sliding lock block, and a spiral compression spring is installed between the lower end of the sliding lock block and the limit sliding groove.

[0018] As a further description of the above technical solution:

[0019] Mounting holes are opened at the four corners of the horizontal end of the U-shaped frame.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present utility model are:

[0021] 1. In this utility model, a feeding hole, a material supporting frame, an electric oil cylinder, a rubber clamping block, a pressure sensor and a controller are arranged on the fixed table. By operating the control switch, the three electric oil cylinders can be controlled to move synchronously inward, and the filter housing can be centripetally clamped between the feeding hole and the middle of the material supporting frame. During this process, the pressure sensor can collect the pressure data applied by the electric oil cylinder to the filter housing in real time, and transmit the pressure data to the controller for calculation, comparison and analysis in real time, so as to display the pressure data on the display screen for the operator to understand the clamping force situation. At the same time, after the pressure value reaches the appropriate range, the controller can control the buzzer to work, reminding the operator that the clamping force of the filter reaches the appropriate range. This structure can realize the automatic centripetal clamping operation of the filter. On the one hand, it reduces the workload and difficulty of the actual clamping and maintenance operation of the filter. On the other hand, it avoids the occurrence of abnormal fixation problems during the maintenance process of the filter, thus improving the stability of clamping and fixation during the maintenance process of the filter.

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present utility model.

[0029] Please refer to Figures 1-3 , the present utility model provides a technical solution: a fixing tool for filter maintenance, including a fixing table 2. The lower end of the fixing table 2 is rotatably installed with a U-shaped frame 1 through a rotary lock part. A material placing hole 201 is opened in the middle of the fixing table 2. A supporting frame 202 is fixedly connected to the middle of the lower end of the fixing table 2 below the material placing hole 201. A clamping mechanism for automatically inductive clamping after the filter is placed is arranged on the fixing table 2.

[0030] Specifically, as Figures 1-3 shown, the clamping mechanism includes three mounting seats 203 fixed at 120° on the lower end of the fixing table 2 and located outside the material placing hole 201, an electric oil cylinder 3 installed on the outside of the three mounting seats 203, a rubber clamping block 301 installed at the inner end of the electric oil cylinder 3, a pressure sensor 4 installed between the inner end of the electric oil cylinder 3 and the rubber clamping block 301, and a controller 5 arranged on the upper end of the fixing table 2 and used for receiving and processing the pressure data of the pressure sensor 4.

[0031] Among them, a display screen 501 is installed on the left side of the front end of the controller 5, a control switch 502 is installed above the right side of the front end of the controller 5, a buzzer 503 is installed below the control switch 502 at the front end of the controller 5. The output ends of the pressure sensor 4 and the control switch 502 are electrically connected to the input end of the controller 5. The output end of the controller 5 is electrically connected to the input ends of the display screen 5*1 and the buzzer 503 respectively. The pressure sensor 4 can collect the pressure data applied by the electric oil cylinder 3 to the filter housing in real time, and thus transmit the pressure data to the controller 5 in real time for calculation, comparison and analysis, so as to control the display screen 501 and the buzzer 503 to perform corresponding operations.

[0032] Specifically, as Figure 1As shown in the figure, the rotary lock part includes a gear disk 6 fixed to the right end of the fixed platform 2 and fitting against the outer wall of the U-shaped frame 1, a limit sliding groove 102 opened at the right end of the U-shaped frame 1 and located below the gear disk 6, a sliding lock block 7 movably installed inside the limit sliding groove 102, and a lock tooth 701 fixed to the upper end of the sliding lock block 7 and meshing with the gear disk 6. An outer end of the sliding lock block 7 is integrally and fixedly connected with a handle 702, which is convenient for an operator to hold and slide-adjust the sliding lock block 7. A spiral compression spring 8 is installed between the lower end of the sliding lock block 7 and the limit sliding groove 102. In a normal state, the sliding lock block 7 can continuously upwardly press and engage with the gear disk 6 to realize the angle locking operation of the fixed platform 2 on the U-shaped frame 1.

[0033] Specifically, as Figures 1-3 shown, mounting holes 101 are opened at four corners of the horizontal end of the U-shaped frame 1.

[0034] Working principle: During use, the U-shaped frame 1 can be placed on a maintenance table, or fixed to the maintenance table using fasteners and the mounting holes 101. Then, the circuit of the fixing tooling is connected to the maintenance table. When performing the clamping and fixing operation of the filter, according to the actual usage habits of the operator, the operator can hold and downwardly press the handle 702 to slide the lock tooth 701 on the sliding lock block 7 downward away from the gear disk 6. At this time, the locking state between the fixed platform 2 and the U-shaped frame 1 is released, and the fixed platform 2 can be rotated and adjusted above the U-shaped frame 1. After the adjustment is completed, the handle 702 can be released. Under the action of the elastic force of the spiral compression spring 8, the lock tooth 701 on the sliding lock block 7 can be upwardly locked to the gear disk 6 to realize the locking operation after the adjustment of the fixed platform 2. When it is necessary to clamp the filter, after the filter housing is downwardly placed between the material discharging hole 201 and the material supporting frame 202, the operator can operate the control switch 502 to control the three electric oil cylinders 3 to synchronously extend outward. When the rubber clamping blocks 301 of the three electric oil cylinders 3 all contact and press against the filter housing, the pressure sensor 4 between the rubber clamping block 301 and the electric oil cylinder 3 will collect the pressure data in real time and transmit it to the controller 5. After the controller 5 calculates, compares, and analyzes the pressure data, the pressure data can be displayed on the display screen 501. When the pressure data reaches the set value range, the buzzer 503 can emit a sound to remind the operator that the clamping and fixing is completed, so that subsequent maintenance and disassembly operations of the filter can be carried out.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
