Description

Technical Field

[0001] This invention relates to the technical field of auxiliary equipment for the production of engine oil pans, and in particular to a fixture for the production of engine oil pans. Background Technology

[0002] The engine oil pan is a component of the engine that is exposed outside the engine compartment of the vehicle. Current oil pan designs typically need to consider the weight of the oil it contains and also need to withstand external impacts to a certain extent, such as gravel from the road.

[0003] During the processing of the oil pan, it needs to be fixed by a fixture, and then holes are drilled in the oil pan.

[0004] An oil pan processing device with application (patent) number CN201520916558.4 includes a base, with a rotary table fixed at both ends of the base and a rotary shaft mounted at the center. A reference base plate is fixed between the rotary shafts. The reference base plate has several through holes corresponding to the bottom holes of the oil pan. A first positioning device for positioning the oil pan and a clamping device for clamping the oil pan positioned on the first positioning device are fixedly installed on the reference base plate. The first positioning device and the clamping device are correspondingly arranged. The clamping device includes a cylinder, a pressure plate and a support plate. The cylinder is fixed on the reference base plate. The pressure plate is hinged to the upper end of the piston rod of the cylinder. The upper end of the support plate is rotatably mounted on the pressure plate and the lower end is rotatably mounted on the cylinder body. Since the first positioning device and the clamping device are both fixed, it is only applicable to the processing of oil pans of one size, thus having poor adaptability. Summary of the Invention

[0006] To achieve the above objectives, the present invention proposes a jig for producing engine oil pans, comprising a base, a frame, several supporting and fixing mechanisms, and several template positioning mechanisms. The base is provided with a frame, and the frame is provided with supporting and fixing mechanisms and template positioning mechanisms. The template positioning mechanisms are used for positioning and fixing the templates, and the supporting and fixing mechanisms are adjusted in position based on the templates. After the position adjustment of the supporting and fixing mechanisms is completed, they meet the supporting and fixing position requirements of the corresponding oil pan.

Detailed Implementation

[0017] See Figure 1 , 2 This invention discloses a jig for producing engine oil pans, comprising a base 1, a frame 2, several supporting and fixing mechanisms 3, and several template positioning mechanisms 4. The base 1 is provided with the frame 2, and the frame 2 is provided with the supporting and fixing mechanisms 3 and the template positioning mechanisms 4. The template positioning mechanisms 4 are used for positioning and fixing templates 5. The supporting and fixing mechanisms 3 are adjusted in position based on templates 5. After the position adjustment of the supporting and fixing mechanisms 3 is completed, it meets the support and fixing position requirements of the corresponding oil pan.

[0018] The number of template positioning mechanisms 4 is four, and the four template positioning mechanisms 4 are respectively set on the four side bodies of the frame 2. The template positioning mechanism 4 includes a support 41 and a positioning pin 42 set on the support 41.

[0019] The template 5 includes a reference body 51, a plurality of connecting ears 52, a plurality of positioning holes 53 and a plurality of positioning grooves 54. The reference body 51 fits into the flange of the corresponding oil pan. The reference body 51 is provided with connecting ears 52 on all four edges. The connecting ears 52 are provided with positioning holes 53. The reference body 51 is provided with positioning grooves 54 on both sides of the connecting ears 52.

[0020] The supporting and fixing mechanism 3 includes an adjusting mechanism 31, a support base 32, a positioning stop 33, and a fixing and pressing mechanism 34. The adjusting mechanism 31 is provided with a support base 32. One end of the support base 32 that supports the template 5 is provided with a positioning stop 33. The support base 32 is provided with a fixing and pressing mechanism 34.

[0021] The lower end of the support 32 rests on the base 1.

[0022] The adjustment mechanism 31 includes a sleeve I311, a tightening screw I312, a sleeve II313, a tightening screw II314, and a connecting rod 315. The sleeve I311 is provided with a tightening screw I312 for fixed connection with the frame 2. The sleeve I311 is provided with a sleeve II313. The sleeve II313 is provided with a connecting rod 315 inside. The sleeve II313 is provided with a tightening screw II314 for tightening and fixing the connecting rod 315.

[0023] The fixing and pressing mechanism 34 includes a cylinder 341, a sliding sleeve 342, a sliding shaft 343, a hook 344, and a tension spring 345. The sliding sleeve 342 is provided with a sliding shaft 343. The driving end of the cylinder 341 is fixedly connected to the lower end of the sliding shaft 343. The upper end of the sliding shaft 343 is provided with a hook 344 that is hinged to it. The two ends of the tension spring 345 are fixedly connected to the hook 344 and the sliding shaft 343, respectively. The sliding sleeve 342 is provided with a bracket 346. The bracket 346 is provided with a support wheel 347. The hook 344 is pressed on the support wheel 347 under the action of the tension spring 345.

[0024] The working process of this invention: In the operation of this invention, a jig for producing engine oil pans involves selecting a template 5 and placing it on a support 41, ensuring that the positioning pin 42 is inserted into the corresponding positioning hole 53. Then, the sliding sleeve I311 and the connecting rod 315 adjust the position of the support 32, so that the positioning stop 33 on the support 32 is engaged in the corresponding positioning groove 54. Then, tighten the tightening screws I312 and II314, remove the template 5, and place the oil pan on the support 32. The positioning stop 33 positions the oil pan and prevents displacement. Then, the cylinder 341 is activated to pull the sliding shaft 343 downward. The sliding shaft 343 pulls the hook 344 downward. Due to the obstruction of the support wheel 347 on the hook 344, the hook 344 changes from a horizontal state to a vertical state. The vertical hook 344 hooks onto the flange of the oil pan and presses it firmly onto the support 32.

[0025] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the scope of protection of the present invention.
