Description

Technical Field

[0001] This utility model relates to the field of brake pump drilling, and in particular to a brake pump housing drilling machine tool. Background Technology

[0002] A drilling machine tool is a machine tool that mainly uses a drill bit to process holes in a workpiece. Typically, the rotation of the drill bit is the primary motion, and the axial movement of the drill bit is the feed motion. In the process of machining a brake pump housing, one step is to drill a hole, and a drilling machine specifically designed for machining brake pump housings is used for this purpose.

[0003] For example, the Chinese utility model patent CN222134152U discloses a drilling machine for machining brake pump housings. It drives two bidirectional threaded rods on both sides to rotate simultaneously via a drive assembly, thereby driving two sliders on both sides to move towards each other within a groove. The upright frame controls the movement of two clamping plates towards each other, thus clamping the brake pump housing and placing it in the middle position of the drilling mechanism for easy drilling. However, this structure still has the following significant drawbacks:

[0004] 1. During the processing, coolant needs to be continuously sprayed in. The iron filings produced during processing can be collected along with the sprayed coolant. However, the existing cleaning equipment is not convenient for quickly recycling the coolant used during processing, which in turn affects the rapid cleaning and recycling of iron filings.

[0005] 2. When replacing drill bits on existing drilling machines, additional tools are used to twist and fix them multiple times, which is cumbersome and inefficient in actual operation. Summary of the Invention

[0006] This utility model aims to solve one of the technical problems existing in the prior art.

[0007] This application provides a brake pump housing drilling machine tool, including a machine tool body, a cooling structure, and a fixture; the machine tool body is provided with a hopper and a storage tank, which are connected by a filter pipe; a filter disc is rotatably installed inside the machine tool body, and the filter disc is provided with a plurality of filter screens on its circumference at equal intervals, all of which can overlap with the filter pipe; the machine tool body is provided with a switching device and a cleaning device; the switching device can drive the filter disc to rotate, so that the filter screen currently overlapping with the filter pipe rotates out and the next filter screen rotates in; the cleaning device is used to clean the rotated-out filter screen.

[0008] Furthermore, the switching device includes a switching motor, a first gear and a second gear. The second gear is fixedly mounted at the bottom of the filter disc. The switching motor is fixedly mounted on the machine tool body, and a first gear that meshes perpendicularly with the second gear is fixedly mounted on its output shaft.

[0009] The axis of the filter disc coincides with the axis of the second gear.

[0010] Furthermore, the cleaning device includes an electromagnet and a pouring plate. The machine tool body is equipped with an inclined pouring plate, and the electromagnet is slidably mounted on the machine tool body and can be positioned directly above the rotating filter screen or pouring plate via a sliding cylinder.

[0011] Furthermore, the size of the filter screens is matched to the filter pipes.

[0012] Furthermore, it also includes a drill bit and a rotating shaft. The rotating shaft has an axial slot that matches the drill bit. Several insertion slots are radially provided in the slot. The drill bit has a mounting slot that corresponds to the insertion slot in the radial direction. Insertion blocks are slidably installed in each mounting slot. One end of the insertion block extends out of the corresponding mounting slot and is inserted into the corresponding insertion slot. The other end is connected to the drill bit through a spring. The drill bit is provided with an unlocking device that can make the insertion blocks completely retract into the corresponding mounting slot.

[0013] Furthermore, the unlocking component includes a rotating block and a connecting post. The rotating block is rotatably mounted on the drill bit. Several arc grooves are evenly distributed on the rotating block. The arc grooves correspond one-to-one with the plug-in blocks. Each plug-in block is fixed with a connecting post that slides in cooperation with the corresponding arc groove.

[0014] Furthermore, the radial distance from each part of the arc groove to the axis of the rotating block is different.

[0015] Furthermore, the drill bit is equipped with a guide block, and the slot is equipped with a guide groove that slides with the guide block.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. By setting up a filter disc and filter screen, iron filings can be separated from the coolant and sent to the storage tank through the filter pipe for recycling. By setting up a switching device and a cleaning device, the filter screen can be automatically replaced and the switched-out filter screen can be cleaned to ensure the filtration efficiency of the filter screen.

[0018] 2. By using the mounting slot, plug-in block, spring, unlocking component, guide block, guide slot and plug-in slot, the drill bit can be installed on the rotating shaft without the need for additional tools, which improves the efficiency of drill bit replacement to a certain extent.

[0027] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0028] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0029] The following description, in conjunction with the accompanying drawings, details a brake pump housing drilling machine provided in this application through specific embodiments and application scenarios.

[0030] Example 1:

[0031] like Figures 1 to 3 As shown in the figure, this application provides a brake pump housing drilling machine tool, including a machine tool body 1, a cooling structure 2 and a fixture 3; the machine tool body 1 is provided with a hopper 11 and a storage tank 12, which are connected by a filter pipe 13; a filter disc 14 is rotatably installed inside the machine tool body 1, and the filter disc 14 is provided with a plurality of filter screens 15 at equal intervals around its circumference, and each filter screen 15 can overlap with the filter pipe 13; the machine tool body 1 is provided with a switching device 4 and a cleaning device 5; the switching device 4 can drive the filter disc 14 to rotate, so that the filter screen 15 currently overlapping with the filter pipe 13 rotates out and the next filter screen 15 is inserted; the cleaning device 5 is used to clean the rotated-out filter screen 15.

[0032] Furthermore, the switching device 4 includes a switching motor 41, a first gear 42 and a second gear 43. The second gear 43 is fixedly mounted at the bottom of the filter disc 14. The switching motor 41 is fixedly mounted on the machine tool body 1, and the first gear 42, which meshes perpendicularly with the second gear 43, is fixedly mounted on its output shaft. The axis of the filter disc 14 coincides with the axis of the second gear 43.

[0033] Furthermore, the cleaning device 5 includes an electromagnet 51 and a pouring plate 52. The machine tool body 1 is provided with an inclined pouring plate 52. The electromagnet 51 is slidably installed on the machine tool body 1 and can be positioned directly above the rotating filter screen 15 or the pouring plate 52 by means of a sliding cylinder 53.

[0034] Furthermore, the size of the filter screen 15 is matched with that of the filter pipe 13.

[0035] In this embodiment of the application, due to the above-mentioned structure, the machine tool body 1 is provided with a cooling structure 2 and a fixture 3. The fixture 3 is used to fix the brake pump housing to prevent it from moving during the drilling process. The cooling structure 2 can continuously spray coolant onto the drill bit 61 and the brake pump housing during the drilling process.

[0036] The switching motor 41 is fixedly installed on the machine tool body 1 by bolts and nuts. The sliding cylinder 53 is a rodless cylinder. The fixed end of the sliding cylinder 53 is fixedly installed on the machine tool body 1 by bolts and nuts, and the output end is fixedly connected to the electromagnet 51, so that the sliding cylinder 53 can push the electromagnet 51 to slide. In the initial state, the electromagnet 51 is located directly above one of the filter screens 15.

[0037] When using this machine tool, the iron filings produced by drilling can enter the filter pipe 13 through the hopper 11 under the influence of the coolant. The filter screen 15, which overlaps with the filter pipe 13, filters the iron filings in the coolant. After filtration, the coolant flows into the storage tank 12.

[0038] After using the machine tool for a period of time, the external program will automatically control the switching motor 41 to start. The switching motor 41 drives the first gear 42 to rotate, the first gear 42 drives the second gear 43 to rotate, and the second gear 43 drives the filter disc 14 to rotate synchronously. The rotation of the filter disc 14 can make the next filter screen 15 overlap with the filter pipe 13, and continue to filter the iron filings in the coolant.

[0039] After the filter disc 14 has finished rotating, the filter screen 15 that has been rotated out is located directly below the electromagnet 51. The external program then controls the electromagnet 51 to generate magnetic force, which can attract the iron filings on the filter screen 15, thereby ensuring the filtration efficiency of the filter screen 15. After the electromagnet 51 has finished attracting the iron filings, it slides to the top of the pouring plate 52 through the sliding cylinder 53. The external program controls the electromagnet 51 to release the magnetic force, and the iron filings fall onto the pouring plate 52 under the action of gravity. The pouring plate 52 is set at an angle on the machine tool body 1, and the iron filings will be collected in the cleaning box through the pouring plate 52.

[0040] Example 2:

[0041] like Figures 4 to 6 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, it also includes a drill bit 61 and a rotating shaft 62. The rotating shaft 62 is axially provided with a slot 621 that matches the drill bit 61. The slot 621 is radially provided with a plurality of insertion slots 622. The drill bit 61 is radially provided with mounting slots 611 corresponding to the insertion slots 622. Insertion blocks 612 are slidably installed in each mounting slot 611. One end of the insertion block 612 extends out of the corresponding mounting slot 611 and is inserted into the corresponding insertion slot 622. The other end is connected to the drill bit 61 through a spring 613. The drill bit 61 is provided with an unlocking member 614, which can make the insertion blocks 612 completely retract into the corresponding mounting slots 611.

[0042] Furthermore, the unlocking component 614 includes a rotating block 615 and a connecting post 616. The rotating block 615 is rotatably mounted on the drill bit 61. Several arc grooves 619 are evenly distributed on the rotating block 615. The arc grooves 619 correspond one-to-one with the plug-in blocks 612. Each plug-in block 612 is fixed with a connecting post 616 that slides in cooperation with the corresponding arc groove 619.

[0043] Furthermore, the radial distances from each part of the arc groove 619 to the axis of the rotating block 615 are all different.

[0044] Furthermore, the drill bit 61 is provided with a guide block 617, and the slot 621 is provided with a guide groove 618 that slides with the guide block 617.

[0045] In this embodiment of the application, due to the above-described structure, both the plug block 612 and the drill bit 61 are provided with mounting holes, and the two ends of the spring 613 are respectively embedded in the corresponding mounting holes to realize the connection between the plug block 612 and the drill bit 61.

[0046] When the drill bit 61 needs to be replaced, pressing the emergency stop button will stop the machine. Rotating the rotating block 615 clockwise will cause the arc groove 619 to rotate synchronously with it. Since each insertion block 612 is fixed with a connecting post 616 that slides into the corresponding arc groove 619, and the radial distance from each part of the arc groove 619 to the axis of the rotating block 615 is different, the clockwise rotation of the arc groove 619 will cause the corresponding connecting post 616 and the corresponding insertion block 612 to slide inwards, compressing the corresponding spring 613, thereby causing the insertion blocks 612 to fully retract into their corresponding positions. Inside the slot 611, the drill bit 61 can be pulled out. Align the guide block 617 on the new drill bit 61 with the guide groove 618, and rotate the rotating block 615 clockwise. The drill bit 61 can then be inserted into the slot 621 until it fits against the bottom of the slot 621. At this point, the mounting slot 611 is aligned with the corresponding insertion slot 622. Release the rotating block 615, and under the action of the corresponding spring 613, the insertion block 612 extends into the corresponding insertion slot 622 and presses against the wall of the corresponding insertion slot 622, thus completing the installation. Finally, press the emergency stop button again to resume operation of the device.

[0047] An external motor and an external cylinder can drive the rotating shaft 62 to rotate and slide up and down, thereby achieving drilling.
