Specific embodiments

[0023] The following will describe in detail the embodiments of the technical solution of the present utility model with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and thus are only examples and cannot be used to limit the protection scope of the present utility model.

[0024] Please refer to Figures 1 to 3 , the present utility model provides a machining fixture for an oil pan with a positioning function, including a base plate 100, a support plate 200, a positioning claw 300, a driving member 400 and a clamping assembly 500.

[0025] Specifically, the base plate 100 is arranged on the workbench of the machining center. The support plate 200 is vertically arranged on the base plate 100, and the front side wall of the support plate 200 is provided with a mounting surface 210, and the end face of the oil pan can be mounted on the mounting surface 210.

[0026] There are four positioning claws 300, and the four positioning claws 300 are arranged in a column symmetrically in pairs. Four symmetrically arranged positioning holes are provided on the end face of the oil pan. The bottom end of the positioning claw 300 is provided with a guiding cone 310 with a gradually decreasing diameter, and the four guiding cones 310 can be inserted into the four positioning holes.

[0027] The driving member 400 is disposed on the supporting plate 200 and connected to the four positioning claws 300 , and can drive the four positioning claws 300 to drive the four guide cones 310 to be inserted into the corresponding positioning holes at the same time.

[0028] There are multiple clamping assemblies 500 , and the multiple clamping assemblies 500 are arranged on the support plate 200 at intervals. The clamping assemblies 500 can press the oil pan onto the mounting surface 210 .

[0029] When in use, the oil pan blank to be processed is first manually pressed onto the mounting surface 210, and then the driving member 400 is driven to drive the four positioning claws 300 to move in the direction of the positioning hole. During the movement, the guide cone 310 is inserted into the corresponding guide hole. During the insertion process, when the guide cone 310 abuts against the side wall of the guide hole, the oil pan can be pushed to move until the positioning claws 300 are inserted into the guide hole. Through four-point positioning, the accuracy of the installation position of the oil pan can be guaranteed. Subsequently, the oil pan is pressed onto the mounting surface 210 through the clamping assembly 500. After the oil pan is clamped and fixed, the machining center can be started to perform subsequent corresponding processing on the oil pan.

[0030] By using the above-mentioned oil pan processing fixture, the four-point positioning of the positioning claws 300 can improve the installation accuracy of the oil pan, thereby improving the processing accuracy. At the same time, the driving member 400 can simultaneously drive all the positioning claws 300 to move and quickly complete the positioning, which can increase the speed of the positioning process and shorten the processing time.

[0031] In this embodiment, the driving member 400 includes a linear motion driving source 410, a push plate 420, a push rod 430 and a connecting rod assembly 440. The linear motion driving source 410 is arranged on the base plate 100 through a bracket. In specific implementation, the linear motion driving source 410 can be a lifting motor commonly used in the prior art. Of course, other linear driving mechanisms can also be selected, such as a gear rack mechanism, an eccentric wheel pushing mechanism, etc.

[0032] The push plate 420 is arranged on the driving shaft of the linear motion driving source 410 and is located on the side away from the mounting surface 210. The linear motion driving source 410 can drive the push plate 420 to move relative to the mounting surface 210. There are two push rods 430, and the two push rods 430 are relatively arranged at the left and right ends of the push plate 420. Two connecting rod assemblies 440 are hinged on each push rod 430, and the two connecting rod assemblies 440 are relatively arranged up and down. The ends of the connecting rod assemblies 440 are respectively connected to the push rod 430 and the corresponding positioning claws 300. The push rod 430 can drive the positioning claws 300 through the connecting rod assemblies 440 to drive the guide cone 310 to be inserted into the positioning hole.

[0033] Specifically, the connecting rod assembly 440 includes a first connecting rod 441, a second connecting rod 442, and a third connecting rod 443. The second connecting rod 442 is vertically and slidably disposed within the support plate 200. One end of the first connecting rod 441 is connected to the push rod 430, and the other end is hinged to the second connecting rod 442. The middle of the third connecting rod 443 is hinged to the support plate 200. One end of the third connecting rod 443 is hinged to the end of the second connecting rod 442, and the other end is fixed to the positioning claw 300. When the push rod 430 approaches the mounting surface 210, it can drive the guiding cone 310 to move towards the mounting surface 210.

[0034] In use, when the linear motion driving source 410 starts to drive the push plate 420 to move towards the mounting surface 210, the end of the third connecting rod 443 can be driven to move towards the mounting surface 210 through the push rod 430, the first connecting rod 441, and the second connecting rod 442, driving the guiding cone 310 to insert into the guiding hole. On the contrary, when the linear motion driving source 410 starts to drive the push plate 420 to move away from the mounting surface 210, the end of the third connecting rod 443 can be driven to move away from the mounting surface 210 through the push rod 430, the first connecting rod 441, and the second connecting rod 442, driving the guiding cone 310 to disengage from the guiding hole.

[0035] As a preferred embodiment, the machining fixture further includes a magnetic adsorption member (not shown in the figure). The magnetic adsorption member is disposed on the support plate 200 and can adsorb and press the oil pan against the mounting surface 210.

[0036] In use, the oil pan can be adsorbed on the mounting surface 210 through the magnetic adsorption member, which facilitates the positioning of the positioning claw 300 when moving the position of the oil pan.

[0037] By using the above-mentioned oil pan machining fixture with a positioning function, through the four-point positioning of the positioning claw 300, the installation accuracy of the oil pan can be improved, thereby improving the machining accuracy. At the same time, by using the driving member 400 to drive the positioning claw 300 for positioning simultaneously, the positioning process speed can be increased and the machining time can be shortened.
