Description

Technical Field

[0001] The utility model relates to the technical field of bus duct processing, in particular to a machine tool fixture structure for processing a bus duct shell. Background Art

[0002] Busbar ducts are enclosed metal structures, primarily constructed of copper or aluminum busbar posts, used to distribute high power to various components in a distributed system. Busbar ducts play a vital role in power systems because they enable efficient transmission and distribution of high currents.

[0003] When processing the bus duct shell, drilling and milling operations are required. Current processing machine tools generally use a vise to clamp the bus duct shell when fixing it. The vise is fixed on the cross slide of the machine tool. However, since the clamping point of the vise is single and the length of the bus duct shell is usually long, it is very easy to cause insufficient force on the bus duct shell during processing. After actual fixation, the two ends of the bus duct shell are prone to shaking during processing, which further affects the processing accuracy and product quality.

[0004] Based on this, in order to further improve the clamping stability of the bus duct shell, we propose a machine tool fixture structure for processing the bus duct shell. Utility Model Content

[0005] The purpose of the utility model is to solve the shortcomings of the prior art, such as the single clamping point of the bench vise and the usually long length of the bus duct shell, which easily leads to insufficient force on the bus duct shell during processing, and to propose a machine tool fixture structure for processing the bus duct shell.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A machine tool fixture structure for processing bus duct housing is designed, comprising a slide unit mounted on a machine platform, a vise unit fixedly mounted on the slide unit, and two support frames located on both sides of the vise unit;

[0008] The support frame slides and is locked in the dovetail groove above the slide unit through a locking assembly. One of the support frames is fixed to the side of the vise unit through a reinforcement assembly. A height adjustment assembly is also provided between the support frame and the slide unit.

[0009] Furthermore, the locking assembly includes a nut seat sliding in the dovetail groove, and a bolt is passed through the end surface of the support frame, and the bolt is threadedly connected to the nut seat.

[0010] Furthermore, the reinforcement assembly includes a connecting plate connected to the side of the vise unit through a fastener, a circular hole for the fastener to move is opened on the end face of the connecting plate, one side of the connecting plate is fixed to the side of the support frame, and a diagonal brace is also fixedly connected between the connecting plate and the support frame.

[0011] Furthermore, the height adjustment assembly includes a gasket fixed to the upper end of the slide unit, and a resistance block is fixedly connected to the bottom of the support frame, and the resistance block is in contact with the gasket.

[0012] Furthermore, the opposing surfaces of the gasket and the abutment block are configured as inclined surfaces.

[0013] Furthermore, a plurality of partitions are installed at intervals on the bottom of the support frame, and the interference block is placed between two adjacent partitions;

[0014] Wherein, a spring plug is embedded on the end surface of the resistance block, and a positioning hole adapted to the telescopic end of the spring plug is opened on the partition.

[0015] The utility model proposes a machine tool fixture structure for processing bus duct shells, which has the beneficial effects of: in the utility model, two additional support frames are installed above the machine tool slide unit to assist the vise unit in clamping and positioning the bus duct shell. Since the two support frames are located on both sides of the vise unit, the supporting force on the bus duct shell is increased, avoiding the problem of a single fixing point of the vise unit during drilling and milling operations, which is prone to shaking of the bus duct shell. Secondly, during the actual operation process, the two ends of the bus duct shell can be clamped and fixed on the support frames by clamps, thereby further enhancing the stability of the bus duct shell processing.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-4 This is an embodiment of the present invention, which discloses a machine tool fixture structure for processing a bus duct housing. The fixture structure includes a slide unit 1 installed on a machine platform, a vise unit 2 fixedly mounted on the slide unit 1, and two support frames 3 located on both sides of the vise unit 2. Specifically, the slide unit 1 is a cross slide, and the specific structure of the slide unit 1 and the vise unit 2 is a conventional method for those skilled in the art, and will not be elaborated on here.

[0023] The support frame 3 slides and is locked in the dovetail groove 11 above the slide unit 1 through the locking component 4. The support frame 3 is fixed to the side of the vise unit 2 through the reinforcement component 5. A height adjustment component 6 is also provided between the support frame 3 and the slide unit 1.

[0024] It should be noted that the support frame 3 described in this embodiment is a T-shaped frame, and a diagonal support rod is fixedly connected to one side of it. The bottom of the T-shaped frame is U-shaped steel and the upper part is angle steel. The design purpose of using U-shaped steel is to ensure support for the upper angle steel while its bottom can also meet the requirements of the bolt 42 for installation.

[0025] In some embodiments, the locking assembly 4 in the present invention includes a nut seat 41 that slides in the dovetail groove 11, and a bolt 42 is passed through the end face of the support frame 3, and the bolt 42 is threadedly connected to the nut seat 41, that is, in this embodiment, the clamping force between the bolt 42 and the nut seat 41 is adjusted to achieve the locking of the sliding position of the support frame 3. Specifically, when the bolt 42 and the nut seat 41 are loosened, the support frame 3 can slide freely. When the bolt 42 and the nut seat 41 are tightened, the position locking of the support frame 3 is completed. In a preferred embodiment, the nut seat 41 and the bolt 42 described in the present invention are provided in plurality to improve the stability of the connection.

[0026] Furthermore, the reinforcement assembly 5 in this embodiment includes a connecting plate 51 connected to the side of the bench vise unit 2 by a fastener, and the fastener is a bolt and nut assembly. A circular hole 52 for the fastener to move is provided on the end surface of the connecting plate 51. Of course, a connecting hole 21 should be provided on the fixing seat of the bench vise unit 2, and the fastener is passed through the connecting hole 21 and the circular hole 52. It should be further explained that the inner diameter of the circular hole 52 in this embodiment should be larger than the outer diameter of the fastener. This design method is because the support frame 3 to which it is connected needs to be height-adjusted during installation. Therefore, in order to meet the demand for position adjustment, the design of a circular hole 52 with a larger aperture is adopted in this embodiment, so that the connecting plate 51 can follow the support frame 3 for a small range of movement and adjustment. One side of the connecting plate 51 is fixed to the side of the support frame 3, and a diagonal brace 53 is also fixedly connected between the connecting plate 51 and the support frame 3.

[0027] Based on the above embodiments, the height adjustment assembly 6 in the present invention includes a gasket 61 fixed to the upper end of the slide unit 1, and the gasket 61 is also fixed to the slide unit 1 by bolts. A resistance block 62 is fixedly connected to the bottom of the support frame 3, and the resistance block 62 is in contact with the gasket 61.

[0028] Secondly, in order to adjust the height within a certain range, the opposing surfaces of the gasket 61 and the interference block 62 in this embodiment are set as inclined surfaces. That is to say, in this embodiment, the interference block 62 and the inclined surface of the gasket 61 are used to support the sliding. When the support frame 3 drives the interference block 62 to move, the height of the support frame 3 is driven to change with the cooperation of the inclined surface of the gasket 61. In this way, the height of the support frame 3 can be adjusted within a certain range. After adjustment, it is necessary to keep the bottom surface of the support frame 3 flush with the end surface of the fixed seat of the vise unit 2, so that the two ends of the shell 7 can be placed horizontally on the bottom surfaces of the support frames 3 on both sides, and at the same time be placed and supported with the fixed seat of the vise unit 2 to form a multi-point support method.

[0029] It should be noted that, in this embodiment, a plurality of partitions 31 are installed at intervals on the bottom of the support frame 3, and the abutment block 62 is placed between two adjacent partitions 31;

[0030] Among them, a spring plug 63 is embedded in the end face of the resistance block 62, and a positioning hole 32 adapted to the telescopic end of the spring plug 63 is opened on the partition 31. The spring plug 63 is a structure well known to technicians in the relevant field. The purpose of using the spring plug 63 to engage the positioning hole 32 is to facilitate the disassembly of the resistance block 62 to improve the convenience of assembly and maintenance.

[0031] During installation, first, according to the required installation position, drill a hole above the slide unit 1 and install the gasket 61. Then, slide the support frame 3 to the predetermined value, and use the interference block 62 at the bottom of the support frame 3 to cooperate with the inclined surface of the gasket 61 to adjust the height of the support frame 3 to ensure that the bottom surfaces of the support frames 3 on both sides are flush with the end surfaces of the fixing seats of the vise unit 2. Then, fix the position of the support frame 3 through the locking assembly 4, and at the same time, connect the support frame 3 located on the side of the vise unit 2 to the vise unit 2 through the reinforcement assembly 5 to complete the adjustment assembly.

[0032] In summary, in the present invention, two additional support frames 3 are installed above the machine tool slide unit 1 to assist the vise unit 2 in clamping and positioning the bus duct shell. Since the two support frames 3 are located on both sides of the vise unit 2, the support force on the bus duct shell is increased, avoiding the problem of the bus duct shell shaking easily due to the single fixing point of the vise unit 2 during drilling and milling operations. Secondly, during the actual operation process, the two ends of the bus duct shell can be clamped and fixed on the support frames 3 by clamps, thereby further enhancing the stability of the bus duct shell processing.

[0033] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
