Description

Technical Field

[0001] The utility model relates to the technical field of oil tank processing, in particular to a clamp for processing an oil tank body of a diesel engine. Background Art

[0002] Plastic diesel tanks have replaced traditional metal tanks in many applications due to their light weight, good corrosion resistance, high safety, and low manufacturing and maintenance costs. When processing diesel engine tanks, the tanks need to be clamped for trimming and painting after injection molding. During the trimming and painting process, fixtures are required to clamp and fix them.

[0003] Most of the existing diesel engine fuel tank clamps are fixed by clamping from the outside of the fuel tank. For example, a diesel engine fuel tank case body processing clamp disclosed in the authorization announcement No. CN214603855U has a clamping method whose strength is difficult to control. If the clamping force is too light, it is easy to cause the fuel tank to shift during the processing, affecting the fuel tank processing effect. If the clamping force is too light, the fuel tank clamp will be easily deformed, affecting the fuel tank product quality. In addition, the existing clamping tools cannot be rotated, resulting in the need for processing personnel to contact and fix, and then manually rotate to the appropriate position before clamping and fixing, which seriously affects the processing efficiency. Therefore, a diesel engine fuel tank case body processing clamp is needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to provide a clamp for processing a diesel engine fuel tank body, which has the advantages of good clamping stability and high processing efficiency, and solves the problems in the prior art that the clamping force of the fuel tank clamp is inconvenient to control, affecting the clamping effect, and the clamp cannot be rotated, affecting the processing efficiency.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a fixture for processing a diesel engine oil tank body, comprising a processing table and a telescopic cylinder, the processing table is provided with a rotating mechanism, and a flexible chuck is provided on the top of the telescopic cylinder and the rotating mechanism;

[0006] The upper end surface of the processing table is provided with a fixed table and a fixed frame, the telescopic cylinder is installed on the side end surface of the fixed table, the rotating mechanism includes a motor and a fixed shaft, the motor is fixedly installed on the side end surface of the fixed frame, the motor is transmission-connected to the fixed shaft, the flexible chuck is installed at the bottom of the fixed shaft, and the flexible chuck on the telescopic cylinder is rotationally connected to the fixed shaft through a bearing.

[0007] As a preferred fixture for machining a diesel engine oil tank body of the utility model, the flexible chuck is made of silicone material and has a cylindrical structure.

[0008] As a preferred fixture for machining a diesel engine oil tank body of the utility model, the top of the flexible chuck is provided with an inwardly recessed arc groove.

[0009] As a preferred fixture for machining a diesel engine oil tank body of the utility model, a spherical cavity is provided inside the flexible chuck.

[0010] As a preferred fixture for machining a diesel engine oil tank body of the utility model, a limit pin elastically connected by a spring is arranged on the upper end surface of the fixed shaft near the flexible chuck end, and the limit pin is a right-angled triangle structure.

[0011] As a preferred fixture for processing a diesel engine oil tank body of the utility model, an angle of five to ten degrees is set between the axis of the fixed shaft and the horizontal plane, a discharge port is set at the lower end of the fixed shaft, and a guide plate is set at the bottom of the discharge port.

[0012] As a preferred fixture for machining a diesel engine oil tank body of the utility model, a foot switch electrically connected to the motor and the telescopic cylinder is provided at the bottom of the machining table.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The utility model adopts a flexible chuck made of silicone material, which has good flexibility and buffering performance, can effectively reduce the rigid impact during the clamping process, and avoid damage or breakage of the side wall of the fuel tank due to excessive clamping force. Especially for diesel tanks with thin walls or fragile materials, it can provide a safer and gentler clamping method. The structure of clamping the diesel tank wall from the inside of the fuel tank avoids the problem of fuel tank shaking caused by excessive clamping force or deformation caused by excessive clamping force, compared with the traditional method of clamping the fuel tank from the outside. An arc groove is provided on the top of the flexible chuck to form a structure similar to a suction cup, which can generate a strong adsorption force when it fits with the side wall of the fuel tank, thereby improving the stability of clamping.

[0015] 2. The utility model adopts the spherical cavity design inside the flexible chuck, so that the flexible chuck can be compressed along the axial direction when under pressure, changing from a columnar shape to a pancake shape, thereby increasing the contact area with the oil tank and further improving the firmness and stability of the clamping.

[0016] 3. The utility model has an ingenious design of a right-angled triangle-shaped limit pin, which makes it easy for the oil drum to be mounted on the fixed shaft. After the processing is completed, the limit pin can effectively prevent the oil drum from being difficult to remove due to adsorption force, thereby simplifying the operation process and improving production efficiency. In addition, the oil tank can be lifted lightly to slide over the limit pin, thereby realizing automatic flow to the next process and reducing the need for manual intervention.

[0017] 4. The fixed axis of the utility model is inclined at a certain angle to the horizontal plane, and a discharge port and a guide plate are provided, so that the processed oil tank can slide smoothly under its own gravity. It is suitable for oil tanks of different sizes and shapes, and there is no need to frequently adjust the fixture, which enhances the versatility and adaptability of the equipment.

DETAILED DESCRIPTION

[0023] See also Figure 1-Figure 4 A fixture for machining a diesel engine oil tank body, comprising a machining table 1 and a telescopic cylinder 2, a rotating mechanism 3 is arranged on the machining table 1, and a flexible chuck 4 is arranged on the top of the telescopic cylinder 2 and the rotating mechanism 3;

[0024] The upper end surface of the processing table 1 is provided with a fixed table 101 and a fixed frame 102, the telescopic cylinder 2 is installed on the side end surface of the fixed table 101, the rotating mechanism 3 includes a motor 310 and a fixed shaft 320, the motor 310 is fixedly installed on the side end surface of the fixed frame 102, the motor 310 is transmission-connected to the fixed shaft 320, the flexible chuck 4 is installed at the bottom of the fixed shaft 320, and the flexible chuck 4 on the telescopic cylinder 2 is rotationally connected to it through a bearing.

[0025] Furthermore, the flexible clamp 4 is made of silicone material and has a cylindrical structure.

[0026] The flexible chuck 4 made of silicone material reduces the chuck rigidity and prevents the chuck from breaking the diesel barrel.

[0027] Furthermore, an inwardly recessed arc groove 401 is provided on the top of the flexible clamp 4 .

[0028] The top of the flexible clamp 4 forms a suction cup structure, so that when the flexible clamp 4 is in contact with the side wall of the oil tank, the oil tank can be sucked, thereby improving the clamping stability.

[0029] Furthermore, a spherical cavity 402 is provided inside the flexible clamp 4 .

[0030] When the flexible clamp 4 is squeezed, the spherical wall can be compressed axially, so that the flexible clamp 4 changes from a columnar structure to a pancake structure, thereby increasing the contact area between the flexible clamp 4 and the oil tank and improving the clamping stability.

[0031] Furthermore, a limiting pin 321 elastically connected by a spring 322 is disposed on the upper end surface of the fixed shaft 320 near the end of the flexible clamp 4 , and the limiting pin 321 is a right-angled triangle structure.

[0032] The right-angled triangle-shaped limit pin 321 allows the oil drum to easily pass over the limit pin 321 when it is mounted on the fixed shaft 320. When sliding downward, the limit pin 321 clamps the inner end surface of the oil drum's refueling port, thereby hanging the oil drum on the fixed shaft 320. When the processing is completed, the limit pin 321 prevents the oil drum from being adsorbed on the flexible chuck 4 at the front end of the telescopic cylinder 2 and being difficult to remove.

[0033] Furthermore, an angle of five to ten degrees is set between the axis of the fixed shaft 320 and the horizontal plane, a discharge port 103 is set at the lower end of the fixed shaft 320 , and a guide plate 104 is set at the bottom of the discharge port 103 .

[0034] The inclined fixed shaft 320 allows the oil tank to slide downward under its own gravity after processing. When it reaches the limit pin 321, the oil tank is gently lifted so that it can pass over the limit pin 321 and slide to the discharge port 103 and slide to the next processing station through the guide plate 104.

[0035] Furthermore, a foot switch 105 electrically connected to the motor 310 and the telescopic cylinder 2 is provided at the bottom of the processing table 1 .

[0036] The operation of the telescopic cylinder 2 and the motor 310 can be conveniently controlled by the foot switch 105, thereby freeing both hands to process the oil tank body.

[0037] When the equipment is in use, align the mouth of the diesel tank to be processed with the fixed shaft 320 and push it upward gently so that the refueling hole of the diesel tank passes over the limit pin 321. As the diesel tank continues to move upward, the flexible chuck 4 will contact the side wall of the tank and generate suction. At the same time, the telescopic cylinder 2 pushes the flexible chuck 4 close to the tank to ensure that the tank is firmly clamped. Step on the foot switch 105 to control the motor 310 to start, drive the rotating mechanism 3 to rotate, and make the tank start to rotate to adapt to the multi-directional processing required. At this time, the operator can use corresponding processing tools (such as grinders and paint spray guns, etc.) to perform all-round and precise processing on the diesel tank. After the processing is completed, control the telescopic cylinder 2 to contract, reduce the pressure on the flexible chuck 4, release the clamping of the tank, and gently lift the refueling port end of the diesel tank upward to make it pass the limit pin 321. Then, under the action of its own gravity, it naturally slides along the inclination angle of the fixed shaft 320 to the discharge port 103, and then slides to the next processing station or collection area through the guide plate 104.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
