Description

Technical Field

[0001] This utility model relates to the technical field of power heads, and in particular to the technical field of a power head with a protective cover structure. Background Technology

[0002] A power head is a power component that can realize main motion and feed motion and has an automatic workpiece circulation function. It drives a gear transmission mechanism through a motor to realize functions such as boring, milling, and drilling. Some also have guide rails to realize linear motion within a small range.

[0003] Currently, when machining workpieces, it is sometimes necessary to machine some holes or grooves in the inner holes or grooves of some workpieces. At this time, the existing standard cutting tools on the machining center cannot reach into the inner holes or grooves for machining, which makes the machining process impossible to achieve.

[0004] To address the problems raised in the background art, for example, application number CN201020579702.7 discloses a power head for internal drilling and milling of workpieces, including an L-shaped housing. Inside the L-shaped housing, a connecting shaft is fixed via bearings. The upper end of the connecting shaft extends out of the upper part of the L-shaped housing, and the lower end is fixed to a first gear. A second gear is fixed via bearings in the horizontal end of the lower part of the L-shaped housing. The first gear meshes with the second gear via an intermediate gear. A tool holder is provided inside the second gear, and the required machining tool is installed in the tool holder. The tool is then moved into the inner hole or groove of the workpiece to be machined, aligning it with the machining position. The machining center is started, and the machining center spindle drives the connecting shaft to rotate. The connecting shaft, via the first gear, intermediate gear, and second gear, drives the tool in the tool holder to rotate, beginning the machining of the workpiece. This method is easy to operate and saves time and effort. However, this device still has the following drawbacks:

[0005] The device lacks protective structures, allowing debris generated when the cutting tool in the tool holder processes the workpiece to easily fly outwards, potentially affecting nearby workers and increasing their risk of injury. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a power head with a protective cover structure that can block debris generated during the processing of workpieces, thereby reducing the risk of injury to workers and improving work safety.

[0007] To achieve the above objectives, this utility model proposes a power head with a protective cover structure, including a power head body, a protective structure, a first protective cover, a second protective cover, an injector, an injector nozzle, a waist-shaped hole, and a clamping mechanism. The protective structure is installed on the processing end of the power head body. The protective structure includes a first protective cover and a second protective cover. The first protective cover is sleeved on the processing end of the power head body, and the second protective cover is installed above the first protective cover. An injector is installed above the second protective cover. The input end of the injector is connected to an external oil supply device through a pipe, and the output end of the injector is connected to an injector nozzle through a pipe. A waist-shaped hole is opened on one side of the upper part of the first protective cover, and the injector nozzle is located in the waist-shaped hole. The oil outlet of the injector nozzle faces the processing direction of the workpiece. A clamping mechanism for clamping the workpiece is provided on one side of the power head body.

[0008] Preferably, the top of the first protective cover has a plurality of first mounting holes, which are arranged at equal intervals.

[0009] Preferably, the front end of the second protective cover is symmetrically provided with extension plates on both sides. Each extension plate is provided with a plurality of second mounting holes that are adapted to the first mounting holes. The second mounting holes are arranged at equal intervals and are aligned with the first mounting holes. The first protective cover and the second protective cover are installed by bolts being screwed into the second mounting holes and the first mounting holes in sequence.

[0010] Preferably, the rear sidewall of the second protective cover is symmetrically provided with a first hinge hole, and the power head body is symmetrically provided with two fixing plates. Each of the two fixing plates is provided with a second hinge hole that matches the first hinge hole. The second protective cover and the fixing plate are hinged by a pin that passes through the first hinge hole and the second hinge hole in sequence.

[0011] Preferably, an oil receiving tank is provided below the oil outlet end of the fuel injector.

[0012] Preferably, the clamping mechanism includes a base, a cylinder, and two grippers. The cylinder is mounted on the base, and the output end of the cylinder is connected to the two grippers.

[0013] The beneficial effects of this utility model are:

[0014] This utility model, by setting a protective structure, can block the debris generated during the processing of the workpiece. Simultaneously, the presence of several first and second mounting holes allows for adjustment of the distance between the first and second protective covers, thereby protecting drill bits of different sizes, increasing the protective area, and reducing the risk of injury to workers. The first and second hinge holes allow for the flipping of the protective structure, facilitating the replacement or cleaning of the drill bits, thus improving the practicality of the structure. This solves the problem of structures lacking protection, where debris generated during workpiece processing by the tool holder easily flies outwards, affecting surrounding workers.

Detailed Implementation

[0021] See Figures 1 to 5This utility model discloses a power head with a protective cover structure, comprising a power head body 1, a protective structure 2, a first protective cover 21, a second protective cover 22, an injector 3, an injector nozzle 4, a waist-shaped hole 5, and a clamping mechanism 6. The protective structure 2 is installed on the machined end of the power head body 1. The protective structure 2 includes a first protective cover 21 and a second protective cover 22. The first protective cover 21 is sleeved on the machined end of the power head body 1, and the second protective cover 22 is installed above the first protective cover 21. A clamping mechanism 6 is installed above the second protective cover 22. There is an injector 3, the input end of which is connected to an external oil supply device through a pipe, and the output end of which is connected to an injector nozzle 4 through a pipe. A waist-shaped hole 5 is provided on one side of the upper part of the first protective cover 21, and the injector nozzle 4 is located in the waist-shaped hole 5. The oil outlet of the injector nozzle 4 faces the processing direction of the workpiece. A clamping mechanism 6 for clamping the workpiece is provided on one side of the power head body 1. By setting the protective structure 2, the debris generated by the workpiece during processing can be blocked, thereby reducing the risk of injury to the workers.

[0022] See Figure 2 The first protective cover 21 has a plurality of first mounting holes 211 on its upper surface. The first mounting holes 211 are arranged at equal intervals, which can realize the adjustment of the distance between the first protective cover 21 and the second protective cover 22, thereby protecting the drill bits of different sizes.

[0023] See Figure 2 The second protective cover 22 has symmetrical extension plates 222 on both sides of its front end. Each extension plate 222 has several second mounting holes 223 that are adapted to the first mounting hole 211. The second mounting holes 223 are arranged at equal intervals and are aligned with the first mounting hole 211. The first protective cover 21 and the second protective cover 22 are installed by screwing bolts into the second mounting holes 223 and the first mounting holes 211 in sequence. When it is necessary to adjust the distance between the first protective cover 21 and the second protective cover 22, the first protective cover 21 is moved forward or backward until the first mounting hole 211 and the second mounting hole 223 are aligned. Finally, the bolts are screwed in to fix it, thereby realizing the adjustment of the distance between the first protective cover 21 and the second protective cover 22.

[0024] See Figure 2 and Figure 3The rear sidewall of the second protective cover 22 is symmetrically provided with a first hinge hole 224. The power head body 1 is symmetrically provided with two fixing plates 7. Each of the two fixing plates 7 is provided with a second hinge hole 71 that matches the first hinge hole 224. The second protective cover 22 and the fixing plate 7 are connected by a pin through the first hinge hole 224 and the second hinge hole 71 in sequence. By setting the first hinge hole 224 and the second hinge hole 71, the protective structure 2 can be flipped, which facilitates the replacement or cleaning of the drill bit and improves the practicality of the structure.

[0025] See Figure 1 The oil nozzle 4 is equipped with an oil collection tank 8 below the oil outlet end. By setting the oil collection tank 8, the lubricating oil sprayed by the oil nozzle 4 can be collected to avoid wasting resources. At the same time, the oil injector 3 can play a role in lubricating the workpiece, thereby improving the processing accuracy.

[0026] See Figure 4 The clamping mechanism 6 includes a base 61, a cylinder 62, and two grippers 63. The cylinder 62 is mounted on the base 61, and its output end is connected to the two grippers 63. Compressed air drives a piston (not shown in the figure), causing the piston to move under pressure. When air pressure acts on the piston, it moves outward or inward, thereby causing the two grippers 63 to move closer or further apart, thus achieving the clamping and fixing of the workpiece.

[0027] The working process of this utility model:

[0028] This utility model discloses a power head with a protective cover structure. During operation, the protective structure 2 can block the debris generated during the processing of the workpiece. At the same time, the setting of several first mounting holes 211 and second mounting holes 223 can realize the adjustment of the distance between the first protective cover 21 and the second protective cover 22, thereby protecting drill bits of different sizes, increasing the protection area, and reducing the risk of injury to workers. The setting of first hinge holes 224 and second hinge holes 71 can realize the flipping of the protective structure 2, thereby facilitating the replacement or cleaning of the drill bits and improving the practicality of the structure.

[0029] The control method of this utility model is to control the device by manually starting and stopping the switch. The wiring diagram of the power element and the supply of power are common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and wiring layout will not be explained in detail.

[0030] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
