[0002] The bearing bush is the part of a sliding bearing that contacts the journal. It has a tile-shaped semi-cylindrical surface that is very smooth and is generally made of wear-resistant materials such as bronze or anti-friction alloys. Currently, bearing bushes are mainly processed by broaching machines. Broaching machines are machine tools that use broaches as cutting tools to process through holes, planes, and shaped surfaces of workpieces. Broaching can achieve high dimensional accuracy and low surface roughness, has high productivity, and is suitable for mass production.

[0003] Currently, broaching machines do not have protective measures during the processing of bearing bushes. The working area of ​​the broaching machine is open, which makes it easy for workers' limbs to enter the working area, posing a safety risk to the workers. It also makes it easy for processing chips to fly everywhere. Summary of the Invention

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0044] Please see Figures 1 to 3 It should be noted that the illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0045] The first aspect of this utility model provides a protective cover for a bearing broaching machine, such as... Figures 1 to 3As shown, the protective cover includes a protective cover body 10, which includes a frame 11. The frame 11 is provided with a first door frame 111 and a second door frame 112. A swing door 12 is hinged on the first door frame 111, and a sliding door 13 is slidably provided on the second door frame 112. The frame 11 is also provided with a feeding window 113 and a discharging window 114. The feeding window 113 is used to pass through the feeding conveyor belt 200, and the discharging window 114 is used to pass through the discharging conveyor belt 300. Specifically, the protective cover also includes a safety interlock structure 20, which includes a magnetic sensor 21 and a magnetic trigger 22. Each first door frame 111 and second door frame 112 is provided with a magnetic sensor 21, and each swing door 12 and sliding door 13 is provided with a magnetic trigger 22.

[0046] The beneficial effects of the protective cover for the bearing broaching machine of this utility model are: during use, such as Figure 1 As shown, the protective cover body 10 is installed around the broaching machine body 100, and the magnetic sensor 21 of the safety interlock structure 20 on the protective cover and the broaching machine body 100 are both connected to an external control unit. This protective cover prevents workers from accidentally touching the working area of ​​the broaching machine and causing injury, greatly improving operational safety. It also prevents iron filings generated during bearing machining from flying everywhere. Furthermore, due to the safety interlock structure, when the swing door 12 and / or sliding door 13 on the protective cover are opened, the magnetic trigger on the swing door 12 and / or sliding door 13 will disconnect from the corresponding magnetic sensor. The magnetic sensor will then send this disconnection signal to the control unit, which will promptly stop the broaching machine body from running, further enhancing the protective performance of the protective cover and ensuring worker safety.

[0047] Furthermore, considering the limitations of the work area, the installation of this protective cover may be difficult. Therefore, preferably, in this embodiment, as... Figure 1 As shown, the protective cover body 10 includes a front protective cover 10a and a rear protective cover 10b, which are detachably connected. With this structural design, during installation, the front protective cover 10a and the rear protective cover 10b can be placed on the front and rear sides of the broaching machine body 100, respectively, and then brought closer together to align, thus covering the broaching machine body 100 within the protective cover body 10 formed by the front and rear protective covers 10a and 10b. This arrangement solves the problem of limited top space (i.e., low height) in the working area of ​​the broaching machine, making it impossible to hoist the protective cover from top to bottom onto the broaching machine body 100; the installation is quick and simple.

[0048] Furthermore, in this embodiment, the front protective cover 10a and the rear protective cover 10b are detachably connected by a connecting piece (not shown in the figure). One end of the connecting piece is connected to the front protective cover 10a by a screw, and the other end is connected to the rear protective cover 10b by a screw. The structure is simple and easy to assemble and disassemble. Specifically, to improve the stability of the connection between the front protective cover 10a and the rear protective cover 10b, in this embodiment, multiple connecting pieces are provided on both the left and right sides of the protective cover body 10. Specifically, multiple connecting pieces are spaced vertically at intervals on the left side of the protective cover body 10 and at the joint between the front and rear protective covers 10a and 10b, and multiple connecting pieces are also spaced vertically at intervals on the right side of the protective cover body 10 and at the joint between the front and rear protective covers 10a and 10b.

[0049] Specifically, such as Figure 1 and Figure 2 As shown, in this embodiment, four first door frames 111 are provided on the front side of the front protective cover 10a, and two first door frames 111 are provided on the right side of the front protective cover 10a. The feed window 113 is provided on the left side of the front protective cover 10a; Figure 3 As shown, a first door frame 111 and a second door frame 112 are provided on the rear side of the rear protective cover 10b, and the discharge window 114 is provided on the right side of the rear protective cover 10b.

[0050] Furthermore, such as Figure 1 As shown, in this embodiment, the swing door 12 includes a first door frame 121, which is hinged to the first door frame 111 via a hinge. A first transparent PC board 122 is provided on the first door frame 121. The sliding door 13 includes a second door frame 131, which is slidably engaged with the second door frame 112. A second transparent PC board 132 is provided on the second door frame 131. By making the door panels of the swing door 12 and the sliding door 13 transparent PC boards, the internal structure of the protective cover body 10 can be clearly displayed, allowing workers to clearly observe the working status of the bed rigging body 100 inside the protective cover. Furthermore, the PC board can maintain stable performance over a wide temperature range, has strong UV resistance, is not prone to aging and yellowing, has a long service life, and is recyclable, making it relatively environmentally friendly. Specifically, in this embodiment, the magnetic trigger 22 of each swing door 12 is set on the first frame 121 of the swing door 12, and the magnetic trigger 22 of each sliding door 13 is set on the second frame 131 of the sliding door 13.

[0051] Specifically, in some other optional embodiments, the first transparent PC board 122 on the first gantry 121 and the second transparent PC board 132 on the second gantry 131 can both be configured with the upper half being a transparent PC board and the lower half being a white PC board, thereby improving the aesthetics of the protective cover and making it look neat and elegant overall.

[0052] Furthermore, such as Figure 1 As shown, in this embodiment, the frame 11 includes multiple vertically extending support columns 101. The bottoms of the multiple support columns 101 are connected by multiple bottom crossbeams 102, and the tops of the multiple support columns 101 are connected by multiple top crossbeams 103. The bottom crossbeams 102 and the bottom ends of the support columns 101 are spaced at a predetermined distance. With this structural design, when the protective cover body 10 is placed on the ground, it is mainly supported by the multiple support columns 101. Because there is a designed distance between the bottom crossbeams 102 at the bottom of the protective cover body 10 and the bottom ends of the support columns 101, when cleaning the working area of ​​the broom, the predetermined distance between the bottom crossbeams 102 and the bottom ends of the support columns 101 allows the broom to easily reach inside the protective cover for cleaning, thus facilitating the cleaning work.

[0053] Another aspect of this utility model provides a bearing broaching machine, which includes a broaching machine body 100, a control unit, and the aforementioned protective cover for the bearing broaching machine. The broaching machine body 100 is disposed inside the protective cover body 10. The magnetic sensors 21 of the safety interlock structure 20 are all electrically connected to the control unit, and the broaching machine body 100 is also electrically connected to the control unit.

[0054] The beneficial effects of this bearing broaching machine are the same as those of the protective cover for the bearing broaching machine mentioned above, so they will not be repeated here.

[0055] In summary, the protective cover and broaching machine for bearing bushes of this invention solve the problems of existing bearing bush broaching machines lacking protective measures during processing, which easily poses safety risks to workers and causes iron filings to fly everywhere. Therefore, this invention effectively overcomes the various shortcomings of the prior art and has high industrial application value.

[0056] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
