Description

Technical Field

[0001] The utility model relates to the technical field of drilling machines, in particular to a drilling fixture used for a multi-hole drilling machine. Background Art

[0002] A drilling machine is a machine tool used for drilling holes or other related processing. It is mainly used to process circular holes on workpieces. A drilling machine can be manually operated or CNC automatically operated. The operation of a drilling machine usually includes fixing the workpiece on a workbench and then drilling with a drill. During the drilling process, the drill enters the workpiece in a rotating manner and forms a hole by cutting. When drilling, cutting fluid may be used to cool and lubricate the drill bit, as well as to help remove chips. The choice of drilling machine depends on the size, shape, material of the workpiece, and the type and precision of the hole required. With the development of technology, CNC drilling machines are becoming more and more popular due to their high efficiency and high precision. Drilling fixtures are used in the process of limiting the workpiece.

[0003] Some existing drilling fixtures are relatively simple in design and are usually only suitable for workpieces of specific shapes and sizes, which limits their versatility and flexibility. In actual applications, since the fixtures cannot adapt to diverse processing requirements, multiple special fixtures may need to be designed and manufactured for workpieces of different shapes and sizes, which not only increases production costs but also reduces production efficiency. In addition, traditional drilling fixtures have shortcomings in chip removal. During high-speed drilling, chips are easily accumulated inside the fixture or on the work surface, which not only affects the processing quality of the workpiece, but may also cause damage to the drill bit or machine tool failure. The accumulation of waste chips may also pose a threat to the safety of the operator and increase the difficulty and time of cleaning work. Therefore, the present application provides a drilling fixture for a multi-hole drilling machine to meet the needs. Utility Model Content

DETAILED DESCRIPTION

[0022] The following is a detailed description of the drilling fixture for a multi-hole drilling machine provided by the utility model in combination with the accompanying drawings and specific embodiments. At the same time, it is explained here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments, and those skilled in the art may also adopt other alternatives to implement some known technologies; and the accompanying drawings are only for a more specific description of the embodiments, and are not intended to specifically limit the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the utility model provides a drilling fixture for a multi-hole drilling machine, including a workbench 1, a limit box 2 and a clamping mechanism 7, the upper surface of the limit box 2 is provided with a V-shaped groove 9, the clamping mechanism 7 includes two L-shaped support frames 701, an inclined plate 702, a telescopic member 703 and a pressing plate 704, the L-shaped support frame 701 is installed on the top of the limit box 2, the inclined plate 702 is connected to the L-shaped support frame 701, the telescopic member 703 is installed on the surface of the inclined plate 702, and the pressing plate 704 is connected to the telescopic member 703.

[0024] The telescopic member 703 may be a pneumatic cylinder or a hydraulic cylinder commonly used in the mechanical manufacturing field.

[0025] like Figure 3 and Figure 4 As shown, the inclined plate 702 is perpendicular to the V-shaped groove 9, and the pressing plate 704 is in contact with the V-shaped groove 9.

[0026] The inclined plate 702 is perpendicular to the V-shaped groove 9, which helps to transmit the force applied to the workpiece along the direction of the inclined plate 702 and the V-shaped groove 9, so as to more effectively disperse and absorb the force generated during the cutting process and reduce the possibility of deformation of the workpiece.

[0027] like Figure 1 , Figure 2 and Figure 3 As shown, the limit box 2 is installed on the top of the workbench 1, and a plurality of support legs 6 are installed on the bottom of the workbench 1, and a support plate 5 is installed on the inner side of the support legs 6.

[0028] A plurality of supporting feet 6 are distributed at the bottom of the workbench 1 , which can ensure that the workbench 1 remains stable during the machining process and reduce vibration or movement caused by cutting force.

[0029] like Figure 1 and Figure 5 As shown, a material storage frame 4 is placed on the top of the support plate 5 , a storage box 10 is provided in the inner cavity of the material storage frame 4 , and a handle is installed on the surface of the storage box 10 .

[0030] The function of the storage frame 4 is to collect waste chips. During drilling or other metal cutting processes, a large amount of metal chips will be generated. The storage frame 4 can easily collect these chips to prevent the chips from being scattered on the workbench 1 or the ground, reduce cleaning work and keep the working environment clean.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, a through hole 8 for cooperating with the limit box 2 is opened on the top of the workbench 1, and a feeding port is opened on the top of the material storage frame 4.

[0032] The through hole 8 is used to discharge the waste chips directly into the material storage frame 4 to prevent the waste chips from accumulating on the surface of the workbench 1, thereby causing inconvenience to subsequent processing.

[0033] like Figure 1 and Figure 2 As shown, the four corners of the workbench 1 are arranged in an arc shape, and the top of the material storage frame 4 is in contact with the workbench 1 .

[0034] The four corners of the workbench 1 are arranged in an arc shape, which can reduce the danger of sharp corners and prevent the corners from being too sharp and causing harm to the staff.

[0035] like Figure 1 and Figure 2 As shown, a controller 3 is installed on the top of the workbench 1, and the controller 3 includes a display screen and control buttons.

[0036] The display screen of the controller 3 can display the current working status, including tool position, processing count, fault diagnosis information, etc., to facilitate real-time monitoring and management.

[0037] The technical solution provided by the utility model is to place the workpiece in the limit box 2, control the telescopic member 703 to extend, limit the two sides of the workpiece, and then drill the workpiece. The waste chips generated during drilling fall into the storage frame 4 through the V-groove 9 and the through hole 8. When the storage frame 4 needs to be cleaned, the storage box 10 can be pulled out.

[0038] The present invention covers any substitution, modification, equivalent method and scheme made on the essence and scope of the present invention. In order to make the public have a thorough understanding of the present invention, specific details are described in detail in the above preferred embodiments of the present invention, and those skilled in the art can fully understand the present invention without the description of these details. In addition, in order to avoid unnecessary confusion about the essence of the present invention, well-known methods, processes, procedures, components and circuits are not described in detail.

[0039] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
