Description

Technical Field

[0001] This utility model relates to the field of engineering machinery technology, and in particular to hydraulic cylinder drilling and milling fixtures. Background Technology

[0002] A drilling and milling fixture is a device specifically designed for drilling and milling hydraulic cylinders in engineering machinery. It combines the functions of drilling and milling, enabling efficient and precise machining of hydraulic cylinders.

[0003] When using a drilling and milling machine to perform drilling and milling on the surface of a hydraulic cylinder, the hydraulic cylinder is usually placed and fixed in the drilling and milling chamber of the drilling and milling machine. Then, the drilling and milling machine is started to drive the internally installed drilling and milling cutter to perform drilling and milling. Because traditional drilling and milling machines usually require the drilling and milling machine to be turned off first, the previously processed hydraulic cylinder is taken out, and then the new hydraulic cylinder is placed and fixed on. This loading process can easily waste drilling and milling time and reduce the efficiency of drilling and milling machine processing. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a hydraulic cylinder drilling and milling fixture.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a hydraulic cylinder drilling and milling fixture, including a drilling and milling machine, wherein the drilling and milling cavity of the drilling and milling machine is provided with a material feeding device, the material feeding device including a hollow frame, a detachable device being provided between one side of the hollow frame and one side of the inner wall of the drilling and milling cavity on the drilling and milling machine, a self-locking motor being fixedly connected to the inner wall of the hollow frame, the output end of the self-locking motor passing through one side of the hollow frame and being fixedly connected to a turntable, a rectangular groove being symmetrically opened on one side of the turntable, a threaded rod being threaded through and connected to the inner wall of the rectangular groove, the threads at both ends of the threaded rod being in opposite directions, and a limit block being threadedly connected to the outer surface of both ends of the threaded rod, one side of the limit block being slidably connected to the inner wall of the rectangular groove.

[0006] The effect achieved by the above-mentioned components is as follows: By setting up a convenient feeding device, when using a drilling and milling machine to drill and mill the surface of the cylinder, the cylinder can be placed between two limit blocks. Then, rotating the threaded rod drives the two limit blocks to move in opposite directions within the inner wall of the rectangular groove, clamping and fixing the cylinder. At this time, the self-locking motor inside the hollow frame is started to drive the turntable to rotate, rotating the fixed cylinder into the drilling and milling cavity on the drilling and milling machine. This will rotate out another pair of limit blocks on the turntable, making it easier to install and fix the second cylinder. By feeding the cylinders that need to be drilled and milled in this staggered manner, the cylinders can be fed and removed without turning off the drilling and milling machine, reducing the drilling and milling feeding time and improving the processing efficiency of the drilling and milling machine.

[0007] Preferably, an anti-slip block is fixedly connected to one side of the limiting block, and the anti-slip block is made of rubber.

[0008] The effect achieved by the above components is that by setting anti-slip blocks, the contact friction on one side of the limit block can be increased, making it more secure and less prone to shaking when clamping and fixing the hydraulic cylinder.

[0009] Preferably, one end of the threaded rod is fixedly connected to a bearing, and the outer ring of the bearing is fixedly connected to one side of the inner wall of the rectangular groove.

[0010] The effect achieved by the above components is that by setting bearings, one end of the threaded rod can be limited while reducing rotational wear between the threaded rod and the inner wall of the rectangular groove, thereby improving the service life and stability of the threaded rod.

[0011] Preferably, a telescopic plate is fixedly connected to one side of the limiting block, and one end of the telescopic plate is fixedly connected to one side of the inner wall of the rectangular groove.

[0012] The effect achieved by the above components is that by setting up the telescopic plate, the gap between one side of the limiting block and the inner wall of the rectangular groove can be protected and covered, so as to prevent the debris generated during the drilling and milling process from falling into the rectangular groove and causing jamming and affecting the use of the threaded rod.

[0013] Preferably, the detachable device includes a groove block, the inner wall of which is symmetrically provided with locking holes, the hollow frame is inserted into the inner wall of the groove block, both sides of the hollow frame are provided with sliding grooves, a spring is fixedly connected to one side of the inner wall of the sliding groove, a locking block is fixedly connected to one end of the spring, and one end of the locking block is inserted into the inner wall of the locking hole.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up a detachable device, when the turntable needs to be maintained or replaced, the locking block can be manually held and pressed inward to a certain position in the inner wall of the slide groove, causing the spring to contract and its other end to be pulled out of the locking hole. Then, the turntable can be pulled upward to pull its hollow frame out of the inner wall of the groove block, thereby removing the turntable from the drilling and milling machine for easy replacement.

[0015] Preferably, one end of the hollow frame has a trapezoidal longitudinal section, and the dimension of the end of the hollow frame away from the turntable is smaller than the dimension of the other end.

[0016] The effect achieved by the above components is that by setting one end of the hollow frame in a trapezoidal shape, the area of ​​one end of the hollow frame can be reduced, making it easier to quickly align with the inner wall of the groove block and facilitate its installation.

[0017] Preferably, the longitudinal section of the card block is U-shaped, and the height of the end of the card block near the turntable is higher than the height of the other end.

[0018] The effect achieved by the above-mentioned components is that by making the height of one end of the locking block closer to the turntable higher than the other end, it is easier to operate and observe when removing it, and it is also easier to pull the other end out of the locking hole.

[0019] Preferably, a telescopic rod is fixedly connected to one side of the inner wall of the slide, one end of the telescopic rod is fixedly connected to one side of the locking block, and the outer surface of the telescopic rod is sleeved and connected to the inner wall of the spring.

[0020] The effect achieved by the above components is that by setting the telescopic rod, the inner wall of the spring can be supported and reinforced, making it less prone to damage during use.

[0021] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0022] In this invention, by setting up a convenient feeding device, when using a drilling and milling machine to drill and mill the surface of a hydraulic cylinder, the hydraulic cylinder can be placed between two limit blocks. Then, rotating the threaded rod drives the two limit blocks to move in opposite directions within the inner wall of the rectangular groove, clamping and fixing the hydraulic cylinder. At this time, the self-locking motor inside the hollow frame is started to drive the turntable to rotate, rotating the fixed hydraulic cylinder into the drilling and milling cavity on the drilling and milling machine. This will rotate out another pair of limit blocks on the turntable, making it easier to install and fix the second hydraulic cylinder.

Detailed Implementation

[0028] Example 1, such as Figure 1-4 As shown, the hydraulic cylinder drilling and milling fixture includes a drilling and milling machine 1. The drilling and milling cavity of the drilling and milling machine 1 is equipped with a material feeding device 2. The material feeding device 2 includes a hollow frame 21. A detachable device 3 is provided between one side of the hollow frame 21 and one side of the inner wall of the drilling and milling cavity on the drilling and milling machine 1. A self-locking motor 22 is fixedly connected to the inner wall of the hollow frame 21. The output end of the self-locking motor 22 passes through one side of the hollow frame 21 and is fixedly connected to a turntable 23. A rectangular groove 24 is symmetrically opened on one side of the turntable 23. A threaded rod 25 is passed through and connected to the inner wall of the rectangular groove 24. The threads at both ends of the threaded rod 25 are in opposite directions. Limiting blocks 26 are threadedly connected to the outer surfaces of both ends of the threaded rod 25. One side of the limiting block 26 is slidably connected to the inner wall of the rectangular groove 24. When using the drilling and milling machine 1 to drill and mill the surface of the hydraulic cylinder, the hydraulic cylinder can be placed between two limiting blocks 26. Then, rotating the threaded rod 25 drives the two limiting blocks 26 to move in opposite directions within the inner wall of the rectangular groove 24, clamping and fixing the hydraulic cylinder. Then, the self-locking motor 22 inside the hollow frame 21 is activated, causing the turntable 23 to rotate, rotating the fixed hydraulic cylinder into the drilling and milling cavity on the drilling and milling machine 1. This will cause another pair of limiting blocks 26 on the turntable 23 to rotate out, facilitating the installation and fixing of the second hydraulic cylinder. By using this staggered method to feed the hydraulic cylinders that need drilling and milling, the drilling and milling machine 1 can be fed and removed without shutting it down, reducing the drilling and milling feeding time and improving the processing efficiency of the drilling and milling machine 1. It should be noted that the self-locking motor 22 is a mature drive technology and equipment in the existing field; its internal structure, connection method, and principle will not be elaborated further.

[0029] Reference Figure 1-4 As shown, this embodiment discloses that a rubber anti-slip block 27 is fixedly connected to one side of the limiting block 26. By setting the anti-slip block 27, the contact friction on one side of the limiting block 26 can be increased, making it more secure and less prone to shaking when clamping and fixing the hydraulic cylinder. A bearing 28 is fixedly connected to one end of the threaded rod 25, and the outer ring of the bearing 28 is fixedly connected to one side of the inner wall of the rectangular groove 24. By setting the bearing 28, one end of the threaded rod 25 can be limited while reducing rotational wear between the threaded rod 25 and the inner wall of the rectangular groove 24, thereby improving the service life and stability of the threaded rod 25.

[0030] Reference Figure 1-4 As shown in the figure, this embodiment discloses that a telescopic plate 29 is fixedly connected to one side of the limiting block 26, and one end of the telescopic plate 29 is fixedly connected to one side of the inner wall of the rectangular groove 24. By setting the telescopic plate 29, the gap between one side of the limiting block 26 and the inner wall of the rectangular groove 24 can be protected, preventing debris generated during drilling and milling from falling into the rectangular groove 24 and causing it to jam and affect the use of the threaded rod 25.

[0031] Reference Figure 1-4 As shown, this embodiment discloses a detachable device 3 including a recessed block 31. The inner wall of the recessed block 31 has symmetrically arranged locking holes 32. A hollow frame 21 is inserted into the inner wall of the recessed block 31. Slide grooves 33 are provided on both sides of the hollow frame 21. A spring 34 is fixedly connected to one side of the inner wall of the slide groove 33. One end of the spring 34 is fixedly connected to a locking block 35, and one end of the locking block 35 is inserted into the inner wall of the locking hole 32. When maintenance or replacement of the turntable 23 is required, the locking block 35 can be manually grasped and pressed inwards into the inner wall of the slide groove 33 to a certain position, causing the spring 34 to contract and its other end to be pulled out of the locking hole 32. Then, the turntable 23 can be pulled upwards to remove its hollow frame 21 from the inner wall of the recessed block 31, thereby removing the turntable 23 from the drilling and milling machine 1 for easy replacement.

[0032] Reference Figure 1-4 As shown, this embodiment discloses that one end of the hollow frame 21 has a trapezoidal longitudinal section, and the dimension of the end of the hollow frame 21 away from the turntable 23 is smaller than the dimension of the other end. By setting one end of the hollow frame 21 to a trapezoidal shape, the area of ​​one end of the hollow frame 21 can be reduced, making it easier to quickly align with the inner wall of the groove block 31 and facilitating its installation. The longitudinal section of the locking block 35 is U-shaped, and the height of the end of the locking block 35 near the turntable 23 is higher than the height of the other end. By making the height of the end of the locking block 35 near the turntable 23 higher than the other end, it is easier to operate and observe it when removing it, and it is easier to pull its other end out of the locking hole 32. A telescopic rod 36 is fixedly connected to one side of the inner wall of the slide groove 33. One end of the telescopic rod 36 is fixedly connected to one side of the locking block 35, and the outer surface of the telescopic rod 36 is sleeved and connected to the inner wall of the spring 34. By setting the telescopic rod 36, the inner wall of the spring 34 can be supported and reinforced, making it less prone to damage during use.

[0033] Working principle: When using the drilling and milling machine 1 to drill and mill the surface of the hydraulic cylinder, the hydraulic cylinder can be placed between two limit blocks 26. Then, the threaded rod 25 is rotated to drive the two limit blocks 26 to move in opposite directions in the inner wall of the rectangular groove 24, clamping and fixing the hydraulic cylinder. At this time, the self-locking motor 22 inside the hollow frame 21 is started to drive the turntable 23 to rotate, rotating the fixed hydraulic cylinder into the drilling and milling cavity on the drilling and milling machine 1. This will rotate out another pair of limit blocks 26 on the turntable 23, making it easier to install and fix the second hydraulic cylinder. By feeding the hydraulic cylinder that needs to be drilled and milled in this staggered manner, it is possible to feed and remove the hydraulic cylinder without turning off the drilling and milling machine 1, reducing the drilling and milling feeding time and improving the processing efficiency of the drilling and milling machine 1.

[0034] When the turntable 23 needs maintenance or replacement, the locking block 35 can be manually held and pressed inward into the inner wall of the slide groove 33 to a certain position, causing the spring 34 and the telescopic rod 36 to retract and pull its other end out of the locking hole 32. Then, the turntable 23 can be pulled upward to pull its hollow frame 21 out of the inner wall of the groove block 31, thereby removing the turntable 23 from the drilling and milling machine 1 for easy replacement.
