[0002] With the development of industry, the processing of metal parts, especially deep hole drilling or milling of metal parts, requires automated processing to meet the requirements of low cost, high efficiency and good effect of industrial development. However, some deep hole drilling slides on the market are generally large in size and heavy in weight, which makes the slides easily affected by gravity during lifting and lowering, resulting in uneven lifting speed, making it difficult to achieve uniform lifting and lowering of the slides and difficult to control the slides to achieve uniform lifting and lowering, ultimately resulting in poor drilling and milling accuracy and poor drilling and milling effect on the workpiece. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a multifunctional deep hole drill that balances the gravity of the slide. Its overall structural design can control the uniform lifting and lowering of the slide to avoid the lifting of the slide being affected by its large size and heavy weight. It not only has the advantages of stable operation, stable lifting, uniform lifting speed, high processing positioning accuracy and good processing effect, but also can reduce the volume of equipment, reduce processing costs and improve the yield rate of processed workpieces, and effectively solves the problem that the deep hole drill slide on the market cannot be lifted and lowered at a uniform speed and cannot be controlled to lift and lower at a uniform speed due to its large size and heavy weight. The utility model is achieved through the following technical solutions:

[0004] A multifunctional deep hole drill for balancing the weight of a slide table comprises a bed base and a column, and also comprises a first screw slide table module, which is arranged on the bed base, and the column slides back and forth on the bed base through the first screw slide table module for processing and positioning. The bed base is a functional description of the machine tool bed.

[0005] Through the above technical solution, the column can be moved back and forth on the bed base through the first screw slide module to perform positioning adjustment according to processing needs.

[0006] Preferably, a second screw slide module is provided on the column, and a slide is provided on one side of the second screw slide module. The slide is lifted and lowered on the column through the second screw slide module to position the workpiece for processing; a processing spindle capable of processing the workpiece is installed on one side of the slide.

[0007] Through the above technical solution, the slide can be raised, lowered, positioned and adjusted through the second screw slide module according to the processing position of the workpiece.

[0008] Preferably, a balancing mechanism is provided on both sides of the column adjacent to the second screw slide module, and the balancing mechanism is connected to the slide; a locking device is provided on the side of the slide facing the column to lock the slide on the column after lifting and positioning.

[0009] Through the above technical solution, the balancing mechanism can provide a considerable pulling force to the gravity of the slide, so that the lifting and lowering of the slide is not affected by gravity and can be lifted and lowered at a uniform speed, thereby achieving better control of the movement of the slide, which improves the accuracy of drilling and milling positioning. The locking device can lock the slide after lifting and positioning on the column to facilitate drilling and milling positioning processing of the workpiece, which can avoid the problem of drilling and milling position deviation during the drilling and milling process of the workpiece.

[0010] Preferably, each balancing mechanism includes a driving member and a guide wheel box assembly, wherein the driving member is arranged on the side of the column to provide a considerable pulling force to the gravity of the slide; an output shaft is arranged at the output end of the driving member, one end of the output shaft is connected and installed with the driving member, and the other end is provided with a power sprocket; the guide wheel box assembly is arranged on the column. The driving member is a cylinder.

[0011] Preferably, the guide wheel box assembly includes a guide wheel box, in which the first guide sprocket, the second guide sprocket and the third guide sprocket are arranged in sequence, and a chain is also arranged in the guide wheel box, and the first guide sprocket, the power sprocket, the second guide sprocket and the third guide sprocket are connected by the chain. The guide wheel box refers to a box body for installing the guide sprocket.

[0012] Preferably, a chain fixing piece is provided on the upper part of the column away from the slide, one end of the chain is fixedly mounted on the column through the chain fixing piece, and the other end of the chain is connected and mounted on the slide. The chain fixing piece refers to a fixing piece or a fixing seat used to fix the end of the chain.

[0013] Preferably, the chain is firstly wound around the first guide sprocket and then around the power sprocket, and then the chain is sequentially wound around the second guide sprocket and the third guide sprocket.

[0014] Preferably, the driving member is arranged on the side of the column through a driving mounting member.

[0015] Through the above technical scheme, the driving member can pull the power sprocket to move up and down, and the power sprocket can drive the chain to move when it moves, so that the driving member can provide a pulling force equivalent to its gravity to the slide when it pulls the chain to move through the power sprocket; because the stroke of the output end of the driving member is twice the lifting stroke of the slide, the output end of the driving member only needs half of the full lifting stroke of the slide to complete the lifting of the slide, so that it can realize a layout that can reduce the stroke of the output end of the driving member, so as to reduce the volume of the equipment, and thus reduce the production cost of the equipment.

[0016] Preferably, a locking groove is provided on the side of the column facing the slide. The locking groove is a functional description of the mounting groove.

[0017] Preferably, the locking device comprises a gasket seat, a locking cylinder is provided on one side of the gasket seat, a locking block is provided on the other side of the gasket seat, the locking block is movably installed in the locking groove, and a locking rod is provided through the gasket seat.

[0020] Through the above technical solution, when the locking cylinder drives the locking block to move toward the column through the locking rod, the slide can be tightly fitted on the column. Since there is a tiny gap between the gasket and the column, when the slide is locked on the column by the locking cylinder, the slide and the column will not be deformed due to the locking pressure; when the slide is locked, the drilling and milling operations of the workpiece can be easily positioned to avoid the displacement of the machining spindle installed on the slide during the drilling and milling process and damage to the workpiece, which improves the machining accuracy and the yield rate of the workpiece machining and ensures a good machining effect of the workpiece.

It provides a balancing mechanism on both sides of the column adjacent to the second screw slide module, and the balancing mechanism is connected to the slide, so that the balancing mechanism can provide a pulling force equivalent to the gravity of the slide to the slide, so that the lifting and lowering of the slide is not affected by gravity and can be lifted and moved at a uniform speed. It can better control the movement of the slide to improve the accuracy of drilling and milling positioning, and effectively solves the problem that the deep hole drilling slide on the market cannot be lifted and lowered at a uniform speed and cannot be controlled to lift and lower at a uniform speed due to its heavy weight.

[0024] 3. A driving member and a guide wheel box assembly are provided in each balancing mechanism. When the driving member pulls the chain to move through the power sprocket in the guide wheel box assembly, it can provide a pulling force equivalent to its gravity to the slide. Since the stroke of the output end of the driving member is twice the lifting stroke of the slide, the output end of the driving member only needs half of the full lifting stroke of the slide to complete the lifting of the slide. It can reduce the layout of the stroke of the output end of the driving member to reduce the size of the equipment, thereby reducing the production cost of the equipment, and solves the problem that the deep hole drilling slide on the market cannot be lifted and lowered at a uniform speed and cannot be controlled to lift and lower the slide at a uniform speed due to its large size.

[0034] In this embodiment, refer to Figures 1 to 6 As shown, the utility model is a multifunctional deep hole drill with a balanced slide gravity, comprising a bed base 1 and a column 2, and also comprising a first screw slide module 3, which is arranged on the bed base 1, and the column 2 is installed on the bed base 1 through the first screw slide module 3; a second screw slide module 4 is provided on the column 2, and a slide 5 is provided on one side of the second screw slide module 4, and the slide 5 can be lifted and lowered on the column 2 through the second screw slide module 4 to process and position the workpiece; a processing spindle 6 that can process the workpiece is installed on one side of the slide 5; balancing mechanisms 7 are respectively provided on both sides of the column 2 adjacent to the second screw slide module 4, and the balancing mechanism 7 is connected to the slide 5; a locking device 8 is provided on the side of the slide 5 facing the column 2, and locks the slide 5 on the column 2 after lifting and positioning.

[0035] In one embodiment, each balancing mechanism 7 includes a driving member 71 and a guide wheel box assembly 72. The driving member 71 is arranged on the side of the column 2 to provide a considerable pulling force to the gravity of the slide 5. An output shaft 73 is provided at the output end of the driving member 71. One end of the output shaft 73 is connected and installed with the driving member 71, and the other end of the output shaft 73 is provided with a power sprocket 74. The guide wheel box assembly 72 is arranged on the column 2.

[0036] In one embodiment, the guide wheel box assembly 72 includes a guide wheel box 75, in which a first guide chain wheel 76, a second guide chain wheel 77 and a third guide chain wheel 78 are sequentially arranged, and a chain 79 is also arranged in the guide wheel box 75.

[0038] In one embodiment, the chain 79 is firstly wound around the first guide sprocket 76 and then wound around the power sprocket 74. Then, the chain 79 is wound around the second guide sprocket 77 and the third guide sprocket 78 in sequence.

[0039] In one embodiment, the driving member 71 is disposed on the side of the column 2 through the driving mounting member 10 .

[0040] In one of the embodiments, a locking groove 11 is provided on the side of the column 2 facing the slide 5, and the locking device 8 includes a gasket seat 81, a locking cylinder 82 is provided on one side of the gasket seat 81, and a locking block 83 is provided on the other side of the gasket seat 81. The locking block 83 is movably installed in the locking groove 11, and a locking rod 84 is provided through the gasket seat 81.

[0041] In one embodiment, one end of the locking rod 84 is connected to the output shaft 73 of the locking cylinder 82 , and the other end of the locking rod 84 is screwed to the locking block 83 .

[0042] In one embodiment, one or more gaskets 85 are disposed on one side of the gasket seat 81 facing the column 2 .

[0043] In one of the embodiments, the structural design principle of the multifunctional deep hole drill with balanced slide gravity is as follows: since the column 2 can slide back and forth on the bed base 1 through the first screw slide module 3, the column 2 can move back and forth on the bed base 1 for positioning and adjustment according to processing needs; and a second screw slide module 4 is provided on the column 2, and a slide 5 is provided on one side of the second screw slide module 4. The slide 5 is lifted and lowered on the column 2 by the second screw slide module 4 to position the workpiece for processing, so that the slide 5 can be lifted and lowered, positioned and adjusted according to the processing position of the workpiece to be processed through the second screw slide module 4. It is achieved by respectively providing balancing mechanisms 7 on both sides of the column 2 adjacent to the second screw slide module 4, and each balancing mechanism 7 is connected to the slide 5 to provide a considerable pulling force to the gravity of the slide 5, so that the lifting and lowering of the slide 5 is not affected by gravity and can be lifted and lowered at a uniform speed, thereby achieving better control of the movement of the slide 5, so as to improve the drilling and milling positioning accuracy of the machining spindle 6 installed on the front side of the slide 5 on the workpiece.

[0044] It is achieved by providing a driving member 71 and a guide wheel box assembly 72 in each balancing mechanism 7, the output end of the driving member 71 is provided with an output shaft 73, one end of the output shaft 73 is connected and installed with the driving member 71, and the other end of the output shaft 73 is provided with a power sprocket 74, and the guide wheel box 75 in the guide wheel box assembly 72 is provided with a first guide sprocket 76, a second guide sprocket 77 and a third guide sprocket 78 in sequence. At the same time, it is also achieved by providing a chain fixing member 9 on the upper part of the column 2 away from the slide 5, a chain 79 is connected between the first guide sprocket 76, the power sprocket 74, the second guide sprocket 77 and the third guide sprocket 78, and one end of the chain 79 is fixedly installed on the column 2 through the chain fixing member 9, and the other end of the chain 79 is connected and installed with the slide 5. The above-mentioned structural design enables the driving member 71 to provide a pulling force equivalent to its gravity to the slide 5 when pulling the chain 79 to move through the power sprocket 74, so as to avoid the lifting and lowering of the slide 5 being affected by its own gravity. Since the stroke of the output end of the driving member 71 is twice the lifting stroke of the slide 5, the stroke of the output end of the driving member 71 is only half of the full lifting stroke of the slide 5 to complete the lifting of the slide 5. This structural design can reduce the layout of the stroke of the output end of the driving member 71, thereby reducing the size of the equipment to solve the problem that the current deep hole drilling slide 5 is large in size and difficult to lift at a uniform speed.

[0045] A locking device 8 is provided on the side of the slide 5 facing the column 2. After the slide 5 is lifted and positioned by the second screw slide module 4, the locking device 8 can lock the slide 5 that has completed the lifting and positioning on the column 2 to facilitate the drilling and milling positioning processing of the workpiece. It avoids the phenomenon of drilling and milling position deviation during the drilling and milling process of the workpiece, thereby improving the drilling and milling accuracy of the workpiece and improving the yield of the workpiece.

[0046] The locking device 8 has a locking cylinder 82 on one side of the gasket seat 81, a locking block 83 on the other side of the gasket seat 81, a locking rod 84 penetrating the gasket seat 81, one end of the locking rod 84 connected to the output shaft 73 of the locking cylinder 82, and the other end of the locking rod 84 screwed to the locking block 83, and one or more gaskets 85 are provided on the side of the gasket seat 81 facing the column 2. When the locking cylinder 82 pulls the locking block 83 through the locking rod 84 (that is, the locking cylinder drives the locking block toward the column through the locking rod), the locking cylinder 82 is locked. When the slide 5 is pressed (pressed), the slide 5 can fit tightly on the column 2. Since there is a small gap between the gasket 85 and the column 2, when the slide 5 is locked on the column 2, the slide 5 and the column 2 will not be deformed due to the locking force; and after the slide 5 is locked, the machining spindle 6 can position the drilling and milling of the workpiece to avoid displacement of the slide 5 during the drilling and milling process and damage to the workpiece, which ensures high machining accuracy and good machining effect, so that it can greatly reduce the defective rate of the workpiece, thereby reducing the machining cost.

[0047] Its overall structural design can control the slide 5 to rise and fall at a uniform speed to avoid the lifting of the slide 5 being affected by its large size and heavy weight. It not only has the advantages of stable operation, stable lifting, uniform lifting speed, high processing positioning accuracy and good processing effect, but also can reduce the size of the equipment, reduce processing costs and improve the yield rate of processed workpieces, and effectively solves the problem that the deep hole drilling slide on the market is unable to rise and fall at a uniform speed and cannot be controlled due to its large size and heavy weight.
