Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology, specifically relating to a single-column V-shaped support device, which has the characteristics of simple structure, convenient use and maintenance, low cost and strong practicality. Background Technology

[0002] Currently, when batch processing ultra-long workpieces up to 18m in length with internal holes, the internal holes require honing. Honing the internal holes of such ultra-long workpieces is very rare in the industry, both domestically and internationally. To achieve the required precision during honing, the workpiece must not rotate or shift during the honing process to prevent spiral or net-like patterns from appearing in the internal holes. However, existing support devices on mechanical equipment lack locking capabilities; adding clamping devices is inconvenient. Therefore, a single-column V-shaped support device needs to be designed and manufactured. Its main purpose is to ensure that the support device used in deep hole honing machine tools can effectively support and fix the workpiece, while also being simple in structure, low in cost, and easy to operate. This is significantly different from the patents in the search results and analysis below. Application No.: 202320054568.6, Authorization Announcement No.: CN218904338 U, Patent Name: A workpiece auxiliary support device for deep hole machine tools. This patent application mainly introduces a workpiece auxiliary support device for deep hole machine tools, the purpose of which is to ensure that the bracket body can drive the workpiece to rise and fall stably and adapt to the self-support requirements of workpieces with different outer diameters. Utility Model Content

[0003] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a single-column V-shaped support device that can effectively support and fix the workpiece, and has a simple structure, low cost, and can be quickly installed.

[0004] The technical solution of this utility model is implemented as follows: A single-column V-shaped support device includes a base plate, a threaded top rod passing through a long hole in the middle of the base plate, and a V-shaped block base plate connected to the top of the top rod by screws. The top rod is fastened to the base plate by two fastening nuts arranged on the upper and lower sides of the base plate, and a re-fastening nut is also installed on the fastening nuts to prevent loosening. A rectangular opening groove for honing a chain pin is machined on one side of the V-shaped block base plate. Two parallel V-shaped blocks are welded on the V-shaped block base plate. A hole is drilled at the middle position of one-quarter of one side of the two V-shaped blocks, and a clamping pin is installed and fixed between the two holes. A clamping sleeve passes through the clamping pin. Two V-shaped block pads are fastened to the two V-shaped blocks by screws. On the right side of the two V-shaped blocks... A baffle with a central hole is fixed to the end face by screws. A V-block locking screw is installed in the central hole of the baffle. The front end of the V-block locking screw is also machined with a rectangular slot for the honing chain pin. The chain is installed in the rectangular slot through the chain pin. The rear section of the V-block locking screw is a lead screw. The lead screw section of the V-block locking screw passes through the baffle and is fitted with a V-block locking nut. In use, the honing chain at the front end of the V-block locking screw is first rolled up and wrapped around. Then the workpiece is placed on this V-shaped frame. The honing chain is then wrapped around the workpiece to the rectangular slot opened on one side of the V-block base plate. By tightening the V-block locking nut, the force is converted along the honing chain and the positioning pin to form a "V" shape, which ultimately drives the V-block locking screw to move backward and lock the workpiece.

[0005] The base plate is fixedly installed on the deep hole honing machine tool track by screws, nuts and pressure plates. Specifically, a long strip hole is opened in the middle of the base plate. This long strip hole is an elongated elliptical through groove. Vertical ribs are welded on both sides of the long strip hole on the lower side of the base plate. Steps are machined at both ends of the lower side of the base plate. A top rod passes through the elongated elliptical through groove in the middle of the base plate. The top rod is fixed above and below the elongated elliptical through groove of the base plate by fastening nuts and then tightened by the re-fastening nuts on the fastening nuts on the upper side of the base plate. In use, the left and right steps of the base plate are locked onto the deep hole honing machine tool track and then fixed with screws, nuts and pressure plates.

[0006] By adjusting the upper and lower fastening nuts and the re-fastening nut of the top rod, the single-column V-shaped support device can be raised and lowered. Then, the top rod moves along the groove through the long elliptical through groove in the middle of the base plate. The V-shaped frame composed of two V-blocks and V-block pads supports the workpiece and is fixed by winding the chain, ensuring that the single-column V-shaped support device can adapt to the self-support requirements of workpieces with different outer diameters.

[0007] The top of the top rod is an elliptical stepped plate, and the bottom of the V-shaped block base plate is an elliptical groove. The two are connected by screws. The V-shaped blocks are made into two parallel rows and welded together with the V-shaped block base plate.

[0008] The positive effects of the technical solution of this utility model are as follows:

[0009] 1. By adjusting the upper and lower fastening nuts and the re-fastening nuts of the top rod, the single-column V-shaped support device can be raised and lowered. Then, the top rod moves along the groove through the long slot machined in the middle of the base plate to meet the alignment and centering requirements of the workpiece supported by the V-shaped block and V-shaped pad on the upper part of the single-column device. Finally, the workpiece is fixed by winding with JTRS2422-2 honing chain to ensure that the single-column V-shaped support device can adapt to the self-support requirements of workpieces with different outer diameters.

[0010] 2. This device features a simple structure, ease of use and maintenance, low cost, and strong practicality, making it suitable for widespread use in deep hole honing machines. Attached Figure Description

[0044] The technical solution of this utility model will be further described below with reference to the accompanying drawings.

[0045] Example 1: As shown in the figure, this utility model discloses a single-column V-shaped support device, including a base plate 3, a threaded top rod 1 passing through a long slot in the middle of the base plate 3, and a V-shaped block base plate 6 connected to the top of the top rod 1 by screws. The top rod 1 is fastened to the base plate 3 by two fastening nuts 4 arranged on the upper and lower sides of the base plate 3. A re-fastening nut 5 to prevent loosening is also installed on the fastening nut 4. The top rod 1 has a continuous thread shape. One re-fastening nut 5 and the fastening nut 4 are installed on the upper side of the top rod 1 in an upper-lower order, so that the top rod 1 passes through the center of the through slot of the long slot in the base plate 3. The other fastening nut 4 is installed on the lower side of the top rod 1. The top rod 1 and the base plate 3 are fixed together by the fastening nut 4 and the re-fastening nut 5.

[0046] The top of the top rod 1 is fastened with screws to the V-shaped block base plate 6. A rectangular opening groove is made on the left side of the V-shaped block base plate 6 (the opening groove is used to lock the chain). That is, a rectangular opening groove for locking and honing the chain pin is machined on one side of the V-shaped block base plate 6.

[0047] Two parallel V-shaped blocks 7 are welded onto the V-shaped block base plate 6, that is, one V-shaped block 7 is installed at the front and one at the back of the V-shaped block base plate 6 and the two are fastened together by welding.

[0048] A hole is drilled at the middle position of 1 / 4 on one side of the two V-blocks 7, and a clamping pin 12 is installed and fixed between the two holes. A clamping sleeve 13 is passed through the clamping pin 12; that is, a hole is drilled at the middle position of 1 / 4 of the length of the V-block 7 to fix the clamping pin 12 and the clamping sleeve 13 inside the V-block that passes through the clamping pin 12.

[0049] Two V-block pads 8 are fastened to the two V-blocks 7 with screws. A baffle 9 with a central hole is fixed to the right end face of the two V-blocks 7 with screws, and a V-block locking screw 11 is installed in the central hole of the baffle 9.

[0050] The front end of the V-block locking screw (11) is also machined with a rectangular slot for honing the chain pin. The chain is installed in the rectangular slot through the chain pin, and the opening directly locks the chain. The rear section of the V-block locking screw 11 is a lead screw. The lead screw section of the V-block locking screw 11 passes through the baffle 9 and is fitted with a V-block locking nut 10.

[0051] In use, the chain is rolled up from the gap between the two V-blocks 7 and below the V-block inner clamping sleeve 13 that passes through the V-block clamping pin 12, and set aside for later use. That is, first roll the honing chain at the front end of the V-block locking screw 11 upwards and wrap it around, then place the workpiece on this V-shaped frame, and then wrap the honing chain around the workpiece to the rectangular opening slot opened on one side of the V-block base plate 6. By tightening the V-block locking nut 10, the force is converted along the honing chain and the positioning pin to form a "V" shape force direction, which finally drives the V-block locking screw 11 to move backward and lock the workpiece.

[0052] When using this device to process workpieces, install the base plate of the single-column V-shaped support device on the deep hole honing machine tool track, and then fasten the pressure plate 2 to the bottom of the track with screws; place the workpiece on the top rod, and pass the rolled-up chain over the top of the product and place the chain vertically downward. At the same time, insert the chain pin into the rectangular opening groove on one side of the V-shaped block base plate 6 (the opening groove is used to lock the chain). At this time, the V-block locking nut 10 can be screwed on. At the same time, the V-shaped clamping pin 12 (with the V-block inner clamping sleeve 13 passing through it) and this set of shaft and sleeve assembly form a force conversion effect (making the chain's natural hanging state become horizontal and also subject to force). When the V-block locking screw 11 moves backward, the workpiece is locked with the chain.

[0053] The base plate 3 is fixedly installed on the deep hole honing machine tool track by screws, nuts, and pressure plates 2. The pressure plates 2 and base plate 3 (and the welded vertical ribs on top of base plate 3) are separate components. The entire "single-column V-shaped support device" requires four pressure plates 2. Two pressure plates 2 are positioned at each end of the base plate 3 below it and are tightly attached to the deep hole honing machine track. Simultaneously, the pressure plates 2 are fastened to the deep hole honing machine track and base plate 3 by screws and nuts. The base plate 3 is as follows: Figure 9 , Figure 10 , Figure 11 The three components are shown. The bottom plate 3 has vertical ribs on both sides of the central slot, which are welded to the bottom plate 3. The pressure plate 2 is a separate component. Steps are machined on both ends of the bottom of the vertical through slot of the bottom plate 3. When in use, the steps are stuck in the middle of the track of the deep hole honing equipment. The top rod 1 passes through the long elliptical through slot in the middle of the bottom plate 3. The top rod 1 moves along the long elliptical through slot of the bottom plate 3 to determine its position. The top rod 1 on the upper and lower sides of the bottom plate 3 is fixed by fastening nuts 4 and tightened by re-fastening nuts 5.

[0054] Adjust each top rod 1 in small increments to place the support in the required position, then tighten the fastening nut 4 and the re-tightening nut 5 on the top rod 1 to ensure that the single-column V-shaped support device can be raised and lowered. Then, move the top rod 1 along the groove through the long elliptical through slot in the middle of the base plate to ensure that the workpiece placed on the device (in contact with the two V-blocks 7 and the V-block pad 8) meets the overall centering line requirements. Finally, use a JTRS2422-2 honing chain to wind the workpiece to ensure that the single-column V-shaped support device can adapt to the self-support requirements of workpieces with different outer diameters.

[0055] The top of the top rod 1 is an elliptical stepped plate, and the bottom of the V-shaped block base plate 6 is an elliptical groove. The two are connected by screws. The V-shaped blocks 7 are made into two parallel rows and welded together with the V-shaped block base plate 6.

[0056] The top rod 1, which passes through the middle of the base plate 3, is fastened by two upper and lower fastening nuts 4. A double fastening nut 5 is installed on the fastening nut 4 on the top of the top rod 1, and the top of the top rod 1 is fastened to the V-block base plate 6 by screws. The top of the V-block base plate 6 is connected to the V-block 7 by welding. A V-shaped clamping pin 12 is installed in the middle of the other side of the V-block 7, and a V-block inner clamping sleeve 13 passes through the V-shaped clamping pin 12. The V-shaped clamping pin 12 is secured to the right by the V-block baffle 9 and the V-block locking nut 10. The V-block locking screw 11 is used to lock the workpiece. The front end of the V-block locking screw 11 is machined with a slot for JTRS2422-2 honing chain and a chain pin hole is machined vertically. After the chain pin is disassembled, it is installed into the slot opening at the front end of the V-block locking screw 11 and then passes through the pin. When in use, the base plate 3 of the single column V-type support device is installed on the deep hole honing machine tool track and then fastened with screws, nuts and pressure plate 2. By rotating the V-block locking nut 10, the V-block locking screw 11 is rotated backward to lock the workpiece.

[0057] The middle of the bottom plate 3 is provided with an oblong through groove, vertical ribs are welded at the front and rear of the bottom, and steps are milled on the left and right. A ejector rod 1 passes through the middle through groove of the bottom plate 3. Both ends of the ejector rod 1 are fixed with fastening nuts 4 and further tightened with double fastening nuts 5. The top of the ejector rod 1 is an elliptical stepped disc, which is connected to the elliptical groove at the bottom of the V-block bottom plate 6 by screws; Two V-blocks 7 are fixedly installed side by side on the V-block bottom plate 6 by welding. A V-block backing plate 8 is installed on the upper part of the V-block 7 and fixed by screws. At the same time, holes are drilled in the middle of two side-by-side columns of the V-blocks 7. A pressing pin shaft 12 and a pressing sleeve 13 are inserted through the pressing pin shaft 12. A baffle 9 is installed on the V-block 7 on the right side of the pressing pin shaft 12. The V-block locking nut 10 restricts the V-block locking screw 11. The chain link and pin are inserted into the front-end chain slot and hole of the V-block locking screw 11 and fixed. When in use, the front and rear steps of the bottom plate 3 of the single-column V-shaped support device are clamped on the track of the deep-hole honing machine tool and then fixed with screws, nuts and a pressing plate 2. The JTRS2422-2 honing chain is rolled up along the pressing pin shaft 12 (with a pressing sleeve 13 inserted through the pin shaft). At this time, a workpiece is placed on the upper part of the ejector rod 1. Then the JTRS2422-2 honing chain is wound around the workpiece and vertically downward. The other end of the chain is placed in the rectangular opening groove made on the V-block bottom plate 6. At this time, the V-block locking nut 10 is screwed. At the same time, the combination of the shaft and sleeve of the V-shaped pressing pin shaft 12 (with an inner V-block pressing sleeve 13 inserted through it) forms a function of converting the direction of force (changing the state of the chain hanging naturally into a state where it is also stressed horizontally), that is, the force transformation of the "ji" shape. When the V-block locking screw 11 moves backward, the workpiece is locked with the chain.

[0058] In a single-column V-shaped support device of the present utility model, by installing the bottom plate on a deep-hole honing machine tool, and by adjusting the upper and lower fastening nuts and double fastening nuts of the ejector rod, the single-column V-shaped support device can be lifted and lowered. Then, the ejector rod moves smoothly along the through groove opened in the middle of the bottom plate to meet the need for center alignment and centering adjustment required for workpiece processing on the equipment. Then, the workpiece is placed on the upper part of the single-column device and contacts the V-blocks and V-block backing plates, and is fixed by surrounding it with a chain, ensuring that the single-column V-shaped support device meets the self-support requirements of workpieces with different outer diameters.

[0059] The implementation cases of the present utility model are disclosed as above, including but not limited to the scope of the technical solutions of the present utility model. Local modifications made by using the disclosed content of the above technical solutions, etc., should all belong to the scope of the technical solutions of the present utility model.
