Description

Technical Field

[0001] This utility model relates to the field of intermediate shaft production technology, and in particular to an intermediate shaft drilling and positioning fixture. Background Technology

[0002] The intermediate shaft is a shaft in a car's gearbox. The shaft itself is integrated with the gears, and its function is to connect the first shaft and the second shaft. By changing the gear lever, it selects to mesh with different gears, so that the second shaft can output different speeds, directions, and torques.

[0003] During the machining of the intermediate shaft, pin holes and oil holes need to be machined on its shaft. The drilling positions of the pin holes and oil holes have precision requirements. Currently, there is no dedicated fixture for drilling and positioning intermediate shafts. During drilling, workers need to place the intermediate shaft on a workbench and judge the drilling position based on experience. This results in low drilling accuracy and affects product quality.

[0005] This utility model is achieved through the following technical solution: a drilling and positioning fixture for an intermediate shaft is provided, including a base plate, a support and positioning mechanism and a drilling and positioning mechanism mounted on the base plate. The support and positioning mechanism includes a first support block and a second support block for supporting both ends of the intermediate shaft, and a positioning block for axially limiting the intermediate shaft. The drilling and positioning mechanism includes a drilling template located above the second support block and the positioning block, and a first drilling sleeve and a second drilling sleeve mounted on the drilling template.

[0006] Preferably, both the first support block and the second support block are provided with V-shaped grooves for placing the intermediate shaft. The intermediate shaft is placed horizontally on the first support block and the second support block, with its two ends placed into the V-shaped grooves of the first support block and the second support block, respectively.

[0007] Preferably, the positioning block is located between the first support block and the second support block, and close to the second support block. The top of the positioning block blocks abuts against one shoulder of the intermediate shaft, thus limiting its axial movement. The first and second support blocks limit the vertical movement of the intermediate shaft, and the positioning block limits its horizontal movement.

[0008] Preferably, two vertical mounting holes are provided on the drilling template, and the first drilling sleeve and the second drilling sleeve are each embedded in one of the vertical mounting holes.

[0009] Preferably, the drilling template is installed at the top of the support column, and the lower end of the support column is installed on the base plate.

[0010] Preferably, the first drilling sleeve has a first vertical through hole for the drill bit to pass through when drilling oil holes, and the second drilling sleeve has a second vertical through hole for the drill bit to pass through when drilling pin holes. The cooperation between the positioning block and the first and second drilling sleeves accurately positions the drilling position of the intermediate shaft, improving drilling accuracy and product quality stability.

[0011] Preferably, the first drill sleeve is positioned above the positioning block. This ensures that the first drill sleeve and the positioning block are vertically aligned, providing support during oil hole drilling.

[0012] Preferably, the second drilling sleeve is positioned above the second support block. This arrangement ensures the second drilling sleeve and the second support block are vertically aligned, and the second support block provides support during drilling, further improving drilling stability and quality.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model can accurately position the drilling position of the intermediate shaft by cooperating with the support positioning mechanism and the drilling positioning mechanism, thereby improving the accuracy of the drilling position, the stability of the drilling quality and the product qualification rate, and ensuring product quality.

[0022] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0023] like Figure 1-4 As shown, this utility model includes a base plate 1, a support and positioning mechanism mounted on the base plate 1, and a drilling and positioning mechanism. The support and positioning mechanism includes a first support block 3 and a second support block 4 for supporting both ends of the intermediate shaft 2, and a positioning block 5 for axially limiting the intermediate shaft 2.

[0024] Both the first support block 3 and the second support block 4 are provided with V-grooves 6 for placing the intermediate shaft 2. The intermediate shaft 2 is placed horizontally on the first support block 3 and the second support block 4, with its two ends respectively placed into the V-grooves 6 of the first support block 3 and the second support block 4. The positioning block 5 is located between the first support block 3 and the second support block 4 and is close to the second support block 4. The top of the positioning block 5 blocks one shoulder of the intermediate shaft 2, thereby limiting its axial movement. The first support block 3 and the second support block 4 limit the movement of the intermediate shaft 2 in the vertical direction, and the positioning block 5 limits the movement of the intermediate shaft 2 in the horizontal direction.

[0025] The drilling positioning mechanism includes a drill template 7 located above the second support block 4 and the positioning block 5, and a first drilling sleeve 8 and a second drilling sleeve 9 mounted on the drill template 7. Two vertical mounting holes are provided on the drill template 7, and the first drilling sleeve 8 and the second drilling sleeve 9 are each embedded in one of the vertical mounting holes. The drill template 7 is mounted on the top of the support column 10, and the lower end of the support column 10 is mounted on the base plate 1. The first drilling sleeve 8 has a first vertical through hole 12 for the drill bit to pass through when drilling oil holes, and the second drilling sleeve 9 has a second vertical through hole 13 for the drill bit to pass through when drilling pin holes 11. Through the cooperation of the positioning block 5 and the first and second drilling sleeves 8 and 9, the drilling position of the intermediate shaft 2 can be accurately positioned, improving drilling accuracy and product quality stability.

[0026] The first drilling sleeve 8 is positioned above the positioning block 5, and the second drilling sleeve 9 is positioned above the second support block 4. In this way, the first drilling sleeve 8 and the positioning block 5 are vertically aligned, and the second drilling sleeve 9 and the second support block 4 are vertically aligned. When drilling oil holes, the positioning block 5 provides support, and when drilling pin holes 11, the second support block 4 provides support, which further improves the stability of drilling and improves the drilling quality.

[0027] When drilling the intermediate shaft 2, place the end of the intermediate shaft 2 that needs to be drilled on the second support block 4, and place the other end of the intermediate shaft 2 on the first support block 3. Then move the intermediate shaft 2 horizontally to the right so that the shoulder of the shaft adjacent to the drilling position is blocked on the left side of the top of the positioning block 5. At this time, the positioning of the intermediate shaft 2 is completed. Start the two drill bits in sequence. The drill bit for drilling the oil hole moves down through the first drilling sleeve 8 and drills the oil hole in the intermediate shaft 2. The drill bit for drilling the pin hole 11 moves down through the second drilling sleeve 9 and drills the pin hole 11 in the intermediate shaft 2.

[0028] This invention, through the cooperation of a support positioning mechanism and a drilling positioning mechanism, can accurately position the drilling position of the intermediate shaft 2, thereby improving the accuracy of the drilling position, the stability of the drilling quality, and the product qualification rate, and ensuring product quality.
