Description

Technical Field

[0001] This utility model relates to the field of drilling tooling technology, and in particular to a clamping and fixing mechanism for drilling tooling. Background Technology

[0002] Shaft parts are one of the most common types of hardware parts. Some shaft parts require drilling. To make drilling easier, clamping fixtures are usually used to help fix the shaft parts in place, thus ensuring the drilling accuracy.

[0003] Currently, the existing clamping and fixing fixtures for drilling shaft parts generally adopt an integrated design. After the shaft parts are clamped and fixed, the displacement cannot be adjusted. When performing multi-hole machining on shaft parts, the shaft parts need to be re-clamped and fixed multiple times, which is a cumbersome process. Utility Model Content

[0004] This utility model relates to a clamping and fixing mechanism for drilling fixtures, which solves the problem that existing clamping and fixing fixtures for drilling shaft parts generally adopt an integrated design, which makes it impossible to adjust the displacement after the shaft parts are clamped and fixed. When performing multi-hole machining operations on shaft parts, multiple re-clamping and fixing operations are required, which is a cumbersome process.

[0005] In a first aspect, this utility model provides a clamping and fixing mechanism for drilling fixtures, specifically comprising: a rail base, a lower clamping base, bolts, a lower clamping roller, an arched top frame, a pin, a lifting component, an upper clamping roller, and a screw. The rail base is fixedly installed on a drilling platform, and the lower clamping base is connected to the top of the rail base. Bolts are connected to the outside of the lower clamping base. Two lower clamping rollers are symmetrically installed inside the lower clamping base. The arched top frame is connected to the top of the lower clamping base, and a pin is connected to the top of the lower clamping base, with the pin connected to the arched top frame. A lifting component is connected inside the arched top frame, and the upper clamping roller is installed inside the lifting component. A screw is connected to the top of the lifting component, and the screw is connected to the arched top frame.

[0006] Furthermore, the arched top frame is rotatably connected to the lower clamp. The lower clamp has a fixed insertion hole at the top and a movable insertion hole at the bottom of the arched top frame. The movable insertion hole is connected to the fixed insertion hole, and a pin passes through the fixed insertion hole and the movable insertion hole. When the arched top frame is in the rotatably closed state, the movable insertion hole and the fixed insertion hole are connected, and the pin is inserted into the fixed insertion hole and the movable insertion hole to fix the arched top frame.

[0007] Furthermore, the arched top frame is provided with movable holes on both sides, and the lifting component is provided with sliders on both sides, with the sliders slidably connected in the movable holes.

[0008] Furthermore, the top of the arched top frame is provided with a screw hole B, the screw is threaded into the screw hole B, a handwheel is provided at the top of the screw, and the bottom of the screw is rotatably connected to the lifting component.

[0009] Furthermore, both the lower and upper clamping rollers are fitted with rubber rings. Rotating the screw moves the lifting component, changing the distance between the upper clamping roller and the two lower clamping rollers, so that the bottom of the shaft part contacts the two lower clamping rollers and the top of the shaft part contacts the upper clamping roller.

[0010] Furthermore, the bottom of the lower clamp is provided with a sliding groove, and the lower clamp is slidably connected to the rail seat through the sliding groove. The displacement of the lower clamp can be adjusted according to the needs of multi-hole machining of shaft parts, thereby changing the drilling position of shaft parts to meet the needs of multi-hole machining of shaft parts.

[0011] Furthermore, the bottom of the lower clamp is provided with a screw hole A, and the bolt is threaded into the screw hole A. The inner end of the bolt contacts the rail seat. After the lower clamp is adjusted, the bolt is tightened to fix the lower clamp.

[0012] This utility model provides a clamping and fixing mechanism for drilling fixtures, which has the following beneficial effects:

[0013] When this utility model is in use, the movable insertion hole and the fixed insertion hole are in a connected state when the arched top frame is in a rotating closed state. The pin is inserted into the fixed insertion hole and the movable insertion hole, and the arched top frame is fixed by the pin to ensure the stability of the arched top frame under stress.

[0014] In addition, the slider slides in conjunction with the movable hole to guide the up and down movement of the lifting component. Rotating the screw drives the lifting component to move. Depending on the specifications of the shaft parts to be drilled, the distance between the upper clamping roller and the two lower clamping rollers is changed so that the bottom of the shaft parts contacts the two lower clamping rollers and the top of the shaft parts contacts the upper clamping roller, which achieves the effect of clamping and fixing the shaft parts. The rubber ring increases the frictional resistance of the shaft parts to prevent displacement of the shaft parts and ensure the drilling accuracy of the shaft parts.

[0015] In addition, the lower clamp can be displaced according to the needs of multi-hole machining of shaft parts, so as to change the drilling position of shaft parts and meet the needs of multi-hole machining of shaft parts. After the lower clamp is adjusted, the bolts are tightened to fix the lower clamp, which effectively ensures the stability of drilling of shaft parts.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 4 :

[0028] This utility model proposes a clamping and fixing mechanism for drilling fixtures, including: a rail base 1, a lower clamping seat 2, a bolt 3, a lower clamping roller 4, an arched top frame 5, a pin 6, a lifting component 7, an upper clamping roller 8, and a screw 10; the rail base 1 is fixedly installed on the drilling platform, and the lower clamping seat 2 is connected to the top of the rail base 1, with the bolt 3 connecting to the outside of the lower clamping seat 2; two lower clamping rollers 4 are symmetrically installed inside the lower clamping seat 2, and the arched top frame 5 is connected to the top of the lower clamping seat 2, with the pin 6 connected to the top of the lower clamping seat 2; the lifting component 7 is connected inside the arched top frame 5, and the upper clamping roller 8 is installed inside the lifting component 7; the lifting component... 7. A screw 10 is connected to the top, and the screw 10 is connected to the arched top frame 5. The arched top frame 5 is rotatably connected to the lower clamp 2. The lower clamp 2 is provided with a fixed insertion hole 203 at the top, and a movable insertion hole 501 is provided at the bottom of the arched top frame 5. The movable insertion hole 501 is connected to the fixed insertion hole 203, and the pin 6 passes through the fixed insertion hole 203 and the movable insertion hole 501. When the arched top frame 5 is in the rotated closed state, the movable insertion hole 501 and the fixed insertion hole 203 are connected, and the pin 6 is inserted into the fixed insertion hole 203 and the movable insertion hole 501. The arched top frame 5 is fixed by the pin 6 to ensure the stability of the arched top frame 5 under stress.

[0029] In this embodiment of the utility model, the arched top frame 5 is provided with movable holes 502 on both sides, the lifting component 7 is provided with sliders 701 on both sides, the sliders 701 are slidably connected in the movable holes 502, the top of the arched top frame 5 is provided with screw holes B503, the screw 10 is threadedly connected in the screw holes B503, the top of the screw 10 is provided with a handwheel, the bottom of the screw 10 is rotatably connected to the lifting component 7, and the lower clamping roller 4 and the upper clamping roller 8 are both fitted with rubber rings 9.

[0030] Using the above technical solution, the slider 701 slides with the movable hole 502 to guide the lifting component 7 to move up and down. Rotating the screw 10 drives the lifting component 7 to move. Depending on the specifications of the shaft parts to be drilled, the distance between the upper clamping roller 8 and the two lower clamping rollers 4 is changed so that the bottom of the shaft parts contacts the two lower clamping rollers 4 and the top of the shaft parts contacts the upper clamping roller 8, which achieves the effect of clamping and fixing the shaft parts. The rubber ring 9 increases the frictional resistance of the shaft parts to prevent displacement of the shaft parts and ensure the drilling accuracy of the shaft parts.

[0031] In Example 2, based on Example 1, a sliding groove 201 is provided at the bottom of the lower clamp 2. The lower clamp 2 is slidably connected to the rail seat 1 through the sliding groove 201. A screw hole A202 is provided at the bottom of the lower clamp 2. A bolt 3 is threadedly connected to the screw hole A202. The inner end of the bolt 3 contacts the rail seat 1.

[0032] By adopting the above technical solution, the lower clamp 2 can be displaced and adjusted according to the needs of multi-hole machining of shaft parts, thereby changing the drilling position of shaft parts to meet the needs of multi-hole machining of shaft parts. After the lower clamp 2 is adjusted, the bolt 3 is tightened to fix the lower clamp 2, effectively ensuring the stability of drilling machining of shaft parts.

[0033] The working principle of this embodiment is as follows: First, the shaft part to be drilled is placed on top of the two lower clamping rollers 4. The arched top frame 5 is rotated into a closed state, and the movable insertion hole 501 is connected to the fixed insertion hole 203. The pin 6 is inserted into the fixed insertion hole 203 and the movable insertion hole 501, and the arched top frame 5 is fixed by the pin 6. Next, the screw 10 drives the lifting component 7 to move, changing the distance between the upper clamping roller 8 and the two lower clamping rollers 4, so that the top of the shaft part contacts the upper clamping roller 8, which achieves the effect of clamping and fixing the shaft part. The rubber ring 9 increases the frictional resistance of the shaft part, preventing the shaft part from shifting and ensuring the drilling accuracy of the shaft part. When the shaft part needs to be processed with multiple holes, the lower clamp 2 can be adjusted to change the drilling position of the shaft part to meet the requirements of multi-hole processing of the shaft part. After the lower clamp 2 is adjusted, the bolt 3 is tightened to fix the lower clamp 2.
