Description

Technical Field

[0001] The present invention relates to the technical field of mechanical processing, in particular to a tool for processing 45-degree holes. Background Art

[0002] A reamed-hole bolt is a type of hardware. Its threaded front end provides connection, while the unthreaded rear end provides positioning. While ordinary bolts can withstand both lateral and axial loads, this lateral load is primarily supported by friction due to the preload torque. Reamed-hole bolts, on the other hand, can also withstand both lateral and axial loads, relying on the bolt's inherent shear strength. Their lateral load capacity is significantly higher than that of ordinary bolts, while their axial load capacity is the same as that of ordinary bolts. In a reamed-hole bolt connection, the diameter of the screw portion is the same as the basic dimension of the hole, creating a transition fit (not a clearance fit). When the connected parts slide relative to each other, the bolt's inherent shear resistance prevents movement, requiring only a smaller preload.

[0003] In the production of the company's 70000T series wood chip boats, the flange holes for the propeller shaft and intermediate shaft are connected using hinged bolts. During production, it was discovered that both ends of the bolts had cross-shaped and 45° safety pin holes, located close to the threads, and all holes were required to be through-center. Experience shows that it is difficult to ensure the perpendicularity and 45° orientation of the two holes when machining cross holes on a conventional drill press. Furthermore, the non-stationary nature of radial drilling machines makes it difficult to control hole size and geometric errors. Numerous time is wasted during machining trying to accurately locate the cross center of the part, and the drill bit is prone to misalignment in the arc area near the threads. Using a boring machine to machine the bolts, while the hole size is guaranteed, manually rotating the cross-shaped holes makes it difficult to control their perpendicularity and 45° angles. Furthermore, the cost of the boring machine increases, while efficiency is significantly reduced. Shipbuilding products have high quality requirements, and shipowners' ship inspections maintain strict quality control over every component. Therefore, the workshop formed a research team to address this issue.

[0004] Based on the workpiece's characteristics and the requirements of the drawings, the research team determined the machining direction. Compared to the efficiency and characteristics of drilling and boring machines, the drilling machine's high efficiency made it necessary to design a tooling fixture to solve the problem. The tooling design considered how to ensure the cross-hole perpendicularity and 45° orientation during machining, the removal of scrap metal from the hole, and the clamping of the bolt during machining. First, the tooling was designed to ensure the alignment of the threaded outer diameter and the outer diameter of the bolt after machining, ensuring a clearance of approximately 0.1 mm. Then, when machining the tooling's outer shape, the inner hole served as a reference, creating a regular octagonal shape. This ensured the hole's verticality and 45° orientation, thus ensuring proper hole placement. Finally, the cross-holes were machined using the tooling's flat surface as a reference, based on the bolt hole's position. This tooling design met the design requirements. During the bolt hole machining, a pressure plate was used to hold the workpiece in place, aligning the tooling's holes, and machining proceeded directly. During the flip, a pin was inserted into the first hole to prevent the workpiece and tooling from rotating. Afterwards, the tooling was rotated, resulting in the cross-hole and 45° holes that met the drawing's requirements. Summary of the Invention

It is widely used and there are many varieties.Bench vise is an essential tool for fitters, and it is also the origin of the name of fitter, because most of the fitter's work is done on the bench vise, such as sawing, filing, chiseling, as well as assembly and disassembly of parts. The bench vise is installed on the bench table, with the width of the jaws as the calibration specification. Common specifications range from 75mm to 300mm. The bench vise is very useful. The basic operations of fitter: chiseling, sawing, filing, drilling, tapping, threading, straightening, bending, etc. all require it. The basic operations of fitter are the operating skills that all technical workers must possess. Electricians must use the bench vise when repairing and installing various electrical equipment. In basic operation, the handle drives the movement of the clamp body by driving the screw rod. It has two force amplification mechanisms, one for the handle and the other for the trapezoidal thread transmission. The force amplification ratio is very large, so the clamping force of the jaws is very large, which can reliably fix the workpiece, thereby ensuring that the workpiece will not move when a large force is applied to the workpiece during the bench work. However, because the clamping force is too large, the surface of the workpiece may be clamped. Therefore, when clamping to protect the surface of the workpiece from damage, something softer than the workpiece needs to be placed between the workpiece and the vise jaws to protect the workpiece, such as paper or soft metal.

[0035] The trolley assembly 9 includes a trolley 901, a rotating drum 902, a universal wheel 903, and an armrest 904. The trolley 901 is clamped inside the clamping plate 8, the rotating drum 902 is plugged into the interior of the trolley 901, the universal wheel 903 is plugged into the interior of the rotating drum 902, and an armrest 904 is provided on one side of the trolley 901.

[0036] See also Figure 1-11 , a tooling for 45° hole processing, the rotating box 201 of the rotating group 2 has multiple effects, one is as a support, and the other is as a sliding groove inside, which can facilitate the use of the equipment. The main function of the internal rotating shaft 202 and gear 203 is to drive the gear row on the other side through the gear row on one side, which greatly facilitates the use effect and will not cause offset and other situations.

[0037] The moving group 3 is a structure of two plates on both sides of the rotating box 201. A column 302 is inserted into the inside of the moving plate 301, and the surface of the column 302 is clamped with the shaft 303. The outer surface of the shaft 303 is sleeved with a roller 304. This structure greatly enhances the stability and practicality of the equipment. The movement of the moving group 3 will also be smoother and there will be basically no sluggishness or a lot of friction that hinders the movement.

[0038] The gear row chamber 401 of the gear row group 4 has two purposes: one is to support the movement between the gear row 402 and the rotating box 201, and the other is to drag the moving direction of the moving group 3. The interior of the gear row chamber 401 is hollow, and the gear row 402 is located at the innermost part. The shaft column 403 and the sliding wheel 404 on the surface of the gear row 402 are used to facilitate the sliding of the gear row 402 inside the rotating box 201, which greatly reduces the jerky feeling during movement. While reducing friction, it also reduces unnecessary physical exertion.

[0039] The movable seat 601 of the fixed group 6 can move up and down inside the scale plate 5, which is convenient for adjusting the height to process the product. The surface of the movable seat 601 is provided with a bearing 602, which is fixed to the fixed seat 603. The octagonal punch nut 604 is stuck on the other side of the fixed seat 603. The product inside the octagonal punch nut 604 can be punched at different positions by adjusting the rotation angle of the fixed seat 603. Bearing is an important component in modern mechanical equipment. Its main function is to support the mechanical rotating body and reduce the friction coefficient during its movement. coefficient) and ensure its rotational accuracy. Under the action of cyclic loads, the contact surface of the bearing is prone to fatigue damage, that is, cracking and peeling. This is the main form of bearing damage. Therefore, in order to improve the service life of the bearing, the bearing steel must have a very high contact fatigue strength. When the bearing is working, not only rolling friction but also sliding friction occurs between the rings, rolling elements and cages, which causes continuous wear of the bearing parts. In order to reduce the wear of the bearing parts, maintain the accuracy and stability of the bearing and extend the service life, the bearing steel should have good wear resistance.

[0040] The main function of the vise set 7 is to fix the product and then facilitate operations such as drilling on it with equipment such as a bench drill. The vise seat 701 serves as the base, and the rotation of the cross bolt 704 and the nut 702 is used to control the pinching of the splint 703 on the target. The gasket 705 has anti-slip and anti-detachment effects, which greatly reduces the possibility of accidents and is also extremely practical for the equipment.

[0041] The cart assembly 9 is loaded with processed products via the cart 901, which is then moved by pushing the handrail 904. The universal wheels 903 are steered by the rotating drum 902, significantly improving production efficiency, reducing production costs, and alleviating the physical exertion of workers involved in transportation. The swivel wheels are so-called movable casters, whose structure allows for 360-degree horizontal rotation. Casters are a general term that includes movable casters and fixed casters. Fixed casters lack a swivel mechanism and cannot rotate horizontally, only vertically. These two types of casters are generally used in combination. For example, a cart has two fixed wheels at the front and two movable swivel wheels at the back, near the push handle. The universal wheels 903 are made of rubber. Rubber is a highly elastic polymer material with reversible deformation. It is highly elastic at room temperature and can undergo significant deformation under very small external forces, returning to its original shape after the external force is removed. Rubber is a completely amorphous polymer with a low glass transition temperature (Tg) and a large molecular weight, often exceeding hundreds of thousands.

[0042] There are many unprocessed products stored inside the storage group 10. The upper surface of the storage box 1001 is opened and closed by the cover 1003 through the hinge 1002. The products are put in from the upper opening and rolled out one by one from the lower opening, which makes it convenient for the fixing group 6 to fix and move it.

[0043] The function of the scale plate 5 is to determine whether the scale is accurate based on the scale on its surface. The main function of the clamping plate 8 is to clamp the main cart group 9 to prevent it from running around and causing the equipment to fall and be damaged. The moving handle 11 can control the moving group 3 to move left and right. Pulling it back can control the rotating group 2 and the gear group 4 to move forward and backward to facilitate the fixing group 6 to fix the products to be processed. The triangular baffle 12 blocks the semi-finished products rolled out by the storage group 10. The inside of the equipment base 1 can store some tools and equipment, and spare equipment replacement parts can be put in it, which can be opened and closed through the door panel 13.

[0044] During use, the movable group 3 can be controlled to move to the left to the top by moving the handle 11, and then pulled back to control the rotating group 2 and the tooth row group 4 to move forward and backward, and the product to be processed can be fixed by the fixing group 6. After fixing, the movable group 3 can be controlled to move to the right to the top by moving the handle 11, and then the semi-finished product can be fixed by the vise group 7. After fixing, it can be processed by the bench drill. After processing, change to a 45° angle and continue processing until processing is completed. Finally, release the vise group 7 and move it to the hole in the middle of the equipment base 1 by moving the handle 11, drop it in, and the finished product will finally enter the trolley group 9 to wait for transportation. Finally, repeat the operation as described above.

[0045] In summary, this 45° hole processing tooling controls the moving group to move to the left to the top head by moving the handle, and then pulls it back to control the rotating group and the gear group to move forward and backward. The product to be processed is fixed by the fixing group. After fixation, the moving group is controlled to move to the right to the top head by moving the handle, and other operations can be performed. This structure greatly enhances the practicality of the equipment, and is more convenient and quick to process it, greatly reducing the time wasted in various operations, improving production efficiency, and successfully solving the equipment processing difficulties. It not only ensures the vertical processing requirements of the cross-direction holes and the 45-degree direction holes of the product, but also solves the problem of drill deviation when processing holes near the threaded part, ensuring product quality, and working efficiency. It has been greatly improved by more than 50%, and the processing accuracy of the workpiece has been greatly improved. Compared with the CNC machining center, the processing cost is only one-third, and the tooling can be used many times. On this basis, it can be extended to solve other multi-hole processing workpieces, greatly enhancing the processing effect, and also has extremely high efficiency for future production.
