Description

Technical Field

[0001] The utility model relates to the technical field of crank-connecting rod casting processing, in particular to a crank-connecting rod casting processing positioning device. Background Art

[0002] The crank connecting rod is one of the main transmission parts of the automobile engine. The requirements for the dimensional accuracy, shape accuracy and position accuracy of the connecting rod are very high. However, the rigidity of the connecting rod is relatively poor and it is easy to deform. Therefore, when arranging the process, it is necessary to separate the rough and fine processing procedures of each main surface. Gradually reduce the processing allowance, cutting force and internal stress, and correct the deformation after processing, and finally meet the technical requirements of the parts; when rough machining the crank connecting rod, it is necessary to clamp and position the crank connecting rod;

[0003] According to the Chinese patent announcement number: CN220498494U, a crank-connecting rod casting processing positioning device is disclosed, which is provided with a connecting block, a rectangular plate, a positioning fixture, an anti-slip rubber block, a telescopic rod and a spring. Through the mutual cooperation of the components, the positioning fixture of the crank-connecting rod casting processing positioning device is softly connected to the crank-connecting rod when limiting the crank-connecting rod, so that there is room for movement when the crank-connecting rod is cut, thereby reducing the impact of the cutting force on the crank-connecting rod as a whole, thereby improving the applicability of the crank-connecting rod casting processing positioning device; in this technical solution, the connecting plate and the connecting block are fixedly connected by bolts, resulting in the need to use a specific wrench tool when the position of the positioning fixture under the connecting plate needs to be adjusted, and the adjustment is relatively slow, thereby affecting the processing efficiency of the crank-connecting rod. For this reason, we propose a crank-connecting rod casting processing positioning device. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances. Example

[0025] The crank-connecting rod casting processing and positioning device provided by the utility model is preferably implemented as follows Figures 1 to 6 As shown: a crank-connecting rod casting processing positioning device, including a base plate 1, a clamping assembly 7, a support frame 2 is fixedly installed on the top of the base plate 1, an electric push rod 3 is fixedly installed on the top of the inner wall of the support frame 2, a moving plate 4 is fixedly installed on the output end of the electric push rod 3, a connecting block 5 is fixedly installed on the bottom end of the moving plate 4, an adjusting frame 6 is movably engaged at the bottom end of the connecting block 5, the clamping assembly 7 is fixedly installed on the bottom end of the adjusting frame 6, and a moving limiting mechanism 8 is provided between the adjusting frame 6 and the connecting block 5;

[0026] The movable limiting mechanism 8 comprises a movable groove 801 and a connecting plate 802. The movable groove 801 is provided inside the connecting block 5. The connecting plate 802 is slidably connected to the inner wall of the movable groove 801. A limiting rod 803 is fixedly installed on the back of the connecting plate 802. A rod groove 804 is provided on the inner wall of the movable groove 801. The limiting rod 803 is inserted into the rod groove 804. A spring 805 is surrounded on the outer wall of the limiting rod 803. The spring 805 is fixedly installed between the back of the connecting plate 802 and the inner wall of the movable groove 801. A push plate 806 is fixedly installed on the front of the connecting plate 802. The front of the connecting block 5 is connected to the movable groove 801. 01 is connected with a plate groove 807, the connecting block 5 movably passes through the plate groove 807, a card slot 808 is opened at the top of the adjusting frame 6, a card block 809 is arranged under the push plate 806, the card block 809 is fixedly installed on the front side of the connecting plate 802, a block groove 810 is connected between the front side of the connecting block 5 and the movable groove 801, the card block 809 movably passes through the block groove 810 and is clamped in the card slot 808, a supporting slider 811 is fixedly installed on the inner wall of the adjusting frame 6, a supporting slide groove 812 is opened on the outer wall of the connecting block 5, and the supporting slider 811 is slidably connected with the supporting slide groove 812.

[0027] Specifically, in the above technical solution, when the crank connecting rods of different specifications are clamped and positioned, the push plate 806 can be pressed, so that the push plate 806 drives the connecting plate 802 to move into the movable groove 801, and the connecting plate 802 compresses the spring 805. The connecting plate 802 also drives the clamping block 809 to move into the block groove 810, so that the clamping block 809 inserted into the clamping groove 808 is disengaged from the clamping groove 808. At this time, the clamping block 809 no longer limits the adjustment frame 6. At this time, the adjustment frame 6 can be moved, so that the adjustment frame 6 drives the clamping assembly 7 to move, thereby adjusting the position of the clamping assembly 7 to adapt to the crank connecting rods of different specifications. When the position adjustment of the clamping assembly 7 is completed, the push plate 806 can be released. Plate 806, at this time, the connecting plate 802 will drive the block 809 to extend out of the slot 808 under the restoring force of the spring 805, so that the block 809 at the corresponding position is stuck in the slot 808, thereby limiting and fixing the adjustment frame 6 again to complete the adjustment. This mechanism is convenient for personnel to quickly adjust the position of the clamping assembly 7 to adapt to the clamping positioning of crank connecting rods of different specifications, and solves the problem that the connecting plate and the connecting block 5 are fixedly connected by bolts in the prior art solution, resulting in the need to use a specific wrench tool when the position of the positioning fixture under the connecting plate needs to be adjusted, and the adjustment is relatively slow, thereby affecting the processing efficiency of the crank connecting rod.

[0028] Furthermore, the number of the card blocks 809 and the block slots 810 are both several, and the card blocks 809 are adapted to the block slots 810 and the card slots 808;

[0029] By providing the card block 809 , the card block 809 can be inserted into the card slot 808 , thereby limiting the position of the adjustment frame 6 .

[0030] Furthermore, the number of the limiting rods 803 on the connecting plate 802 is two, and the limiting rods 803 are adapted to the rod grooves 804;

[0031] Among them, by setting the limiting rod 803, the spring 805 can be limited to ensure the stability of the spring 805 when compressed.

[0032] Furthermore, the number of the supporting sliders 811 on the adjustment frame 6 is two, and the supporting sliders 811 are adapted to the supporting slide grooves 812;

[0033] Among them, by providing the supporting slider 811 , a supporting and limiting function can be played on the adjusting frame 6 , so that the adjusting frame 6 can achieve fixed sliding on the connecting block 5 .
