Description

Technical Field

[0001] The utility model belongs to the technical field of drilling equipment, in particular to a drilling system of a main cylinder column piston. Background Art

[0002] The brake master cylinder, also known as the hydraulic brake master cylinder, is a vital component in the automobile braking system. In the design of the brake master cylinder, the piston is one of the key components, responsible for generating and transmitting the necessary braking pressure during the braking process. In order to optimize the performance and efficiency of the brake master cylinder, a dual-chamber design is often used in modern braking systems, which includes a first piston and a second piston (hereinafter collectively referred to as the master cylinder column piston).

[0003] Some master cylinder column pistons usually require multiple circular holes to be opened around the circumference. These circular holes are usually called compensation oil holes and bypass oil holes. These holes are designed to increase the speed of liquid flow and improve the sensitivity and efficiency of braking.

[0004] When drilling multiple circular holes of the main cylinder column piston, if the main cylinder column piston is not perpendicular to the drill bit of the drilling machine when clamped by the clamping mechanism, it is easy to cause the circular holes to be crooked, affecting product quality. When drilling with traditional drilling equipment, the operator usually makes an estimate based on his eyes or experience, which can easily affect the accuracy of the drilling process and affect product quality.

[0026] A second top column is connected to the third bracket by a bearing, and a clamp is provided at one end away from the third bracket, and a second driving member is provided for driving the second top column to rotate;

[0027] The clamping claw is used to extend into the main cylinder column piston and then open it to clamp the main cylinder column piston.

DETAILED DESCRIPTION

[0046] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0047] Embodiment 1:

[0048] This embodiment provides a master cylinder column piston drilling system, comprising:

[0049] A machine base 1 is provided with a machine head mechanism 2 for drilling;

[0050] A clamping mechanism 7 is mounted on the machine base 1 and is used to clamp the main cylinder column piston 6;

[0051] A correction mechanism, mounted on the machine base 1, and used to correct the deviation angle of the master cylinder column piston 6;

[0052] Among them, the specific structure of the head mechanism 2 is an existing mature technology, and its specific structure will not be repeated here. The clamping mechanism 7 can adopt a double-acting clamping cylinder to ensure that the main cylinder column piston 6 can maintain the center in the stroke direction of the double-acting clamping cylinder after clamping, thereby improving the accuracy and avoiding the deviation of the main cylinder column piston 6 due to clamping.

[0053] It can be seen from this embodiment that by setting up a correction mechanism, the deviation angle of the main cylinder column piston 6 is corrected before being clamped by the clamping mechanism 7, thereby ensuring its verticality with the drill bit 20 in the head mechanism 2, improving the accuracy of circular hole processing, and ensuring product quality.

[0054] Embodiment 2:

[0055] This embodiment provides a master cylinder column piston drilling system, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the correction mechanism includes:

[0056] A base 3 is mounted on the base 1;

[0057] An axial limit assembly 4 is mounted on the machine base 1 and is located on one side of the base 3;

[0058] The radial correction assembly 5 is installed on the machine base 1 and is located on the other side of the base 3 .

[0059] It can be seen from this embodiment that the main cylinder column piston 6 is positioned axially through the axial limiting component 4, and then the radial correction component 5 is used to make the axis of the main cylinder column piston 6 parallel to the horizontal plane, so that it can maintain a high verticality with the drill bit 20, improve the processing accuracy, and ensure product quality.

[0060] Embodiment 3:

[0061] This embodiment provides a master cylinder column piston drilling system, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the axial limit assembly 4 includes:

[0062] A first slide rail assembly 40 is mounted on the base 1, and a first bracket 41 is mounted on the output end;

[0063] A first top column 42 is bearing-connected to the first bracket 41 and an abutment joint 43 is provided at one end away from the first bracket 41;

[0064] The locking member 44 is installed on the first bracket 41 and is used to restrict and release the sliding of the first bracket 41 along the first slide rail assembly 40;

[0065] The first slide rail assembly 40 may adopt a structure of a slide rail and a slider, and the first bracket 41 is bolted to the slider;

[0066] The locking member 44 may be a bolt, and the first bracket 41 is provided with a threaded hole threadedly connected to the bolt, and the bolt abuts against the surface of the base 1 to restrict the sliding of the first bracket 41;

[0067] Furthermore, the first push column 42 and the abutment joint 43 are of an integrated structure, and the shape of the abutment joint 43 is determined according to the shape of the inner wall of the piston in the axial direction, so that the two can fit together. The specific shape of the abutment joint 43 is not limited here.

[0068] It can be seen from the present embodiment that one end of the master cylinder column piston 6 is axially limited by the first top column 42 and the abutment joint 43, thereby improving the accuracy of the axial position of the circular hole in the master cylinder column piston 6, improving the processing accuracy, and ensuring product quality.

[0069] Embodiment 4:

[0070] This embodiment provides a master cylinder column piston drilling system, which, in addition to the technical solutions of the above embodiments, also has the following technical features, and the axial limit assembly 4 also includes:

[0071] A scale 45 is mounted on the base 1;

[0072] A pointer 46 is mounted on the first bracket 41;

[0073] The head mechanism 2 includes a drill bit 20 for drilling holes, and the axis of the drill bit 20 is arranged corresponding to the zero point of the scale 45;

[0074] At the same time, the value displayed by the scale 45 can be the distance between one end of the master cylinder column piston 6 and the center of the circular hole. Since the first bracket 41 is not in contact with one end of the master cylinder column piston 6, the installation position of the pointer 46 needs to extend along the side of the first bracket 41 close to the master cylinder column piston 6. The specific extension distance is based on the gap between the first bracket 41 and the master cylinder column piston 6 when the abutment 43 abuts against the axial inner wall of the master cylinder column piston 6. Therefore, the pointer 46 needs to be adjustably connected to the first bracket 41. Specifically, it can be achieved by opening a strip groove on the first bracket 41.

[0075] It can be seen from this embodiment that, by setting the scale 45 and the pointer 46, it is convenient to set the position of the first bracket 41, to position the round hole in the axial direction of the main cylinder column piston 6, to improve the processing accuracy of the round hole, and to improve product quality.

[0076] Embodiment 5:

[0077] This embodiment provides a master cylinder column piston drilling system, which, in addition to the technical solutions of the above embodiments, also has the following technical features: the radial correction component 5 includes:

[0078] The second slide rail assembly 50 is mounted on the base 1, and a second bracket 51 is installed at the output end;

[0079] The first driving member 52 is mounted on the base 1 and is used to drive the second bracket 51 to move closer to or away from the main cylinder column piston 6;

[0080] A third bracket 53 is slidably connected to the second bracket 51;

[0081] A second top column 54 is bearing-connected to the third bracket 53, and a clamping claw 55 is provided at one end away from the third bracket 53, and a second driving member 56 is provided for driving the second top column 54 to rotate;

[0082] The clamping claw 55 is used to extend into the main cylinder column piston 6 and then open it to clamp the main cylinder column piston 6;

[0083] Meanwhile, the second slide rail assembly 50 may adopt a slide rail and a slider, and the second support plate is mounted on the slider;

[0084] The first driving member 52 may be a screw transmission assembly and a servo motor, and a connecting plate is provided between the second bracket 51 and the output end of the screw transmission assembly, and the specific structures of the screw transmission assembly and the servo motor are existing mature technologies and will not be described in detail here;

[0085] The second driving member 56 can be a stepper motor, which is used to rotate the main cylinder column piston 6 at a set angle, so as to facilitate the processing of a circle of circular holes and improve efficiency. The specific structure of the stepper motor is an existing mature technology and will not be described here.

[0086] In addition, a sliding groove is provided on the second bracket 51 , and a sliding block is provided on the third bracket 53 to be slidably connected with the sliding groove.

[0087] It can be seen from this embodiment that the second push column 54 enters the main cylinder column piston 6 under the action of the first driving member 52 and causes the clamping claw 55 to open, so as to adjust and position the main cylinder column piston 6 in the radial direction, thereby improving the processing accuracy and product quality;

[0088] At the same time, the second bracket 51 is slidably connected to the third bracket 53, so that when the second driving member 56 drives the second bracket 51, the clamp 55 is pushed into the main cylinder column piston 6 in advance to avoid the situation where the clamp 55 cannot enter due to large angle deviation.

[0089] Embodiment 6:

[0090] This embodiment provides a master cylinder column piston drilling system, which, in addition to the technical solutions of the above embodiments, also has the following technical features, the clamping jaw 55 includes:

[0091] The main body 550 is coaxially connected to the second top column 54 and has a slide groove 551 axially opened inside, and a plurality of claws 552 are arranged on the circumference of one end away from the second top column 54;

[0092] The third top column 553 is slidably connected in the slide groove 551, and a conical head 554 is provided at one end close to the claw head 552 for propping up the plurality of claw heads 552;

[0093] The plurality of claw heads 552 are each provided with a protrusion 555 that abuts against the inclined surface of the conical head 554;

[0094] At the same time, the protrusion 555, the claw head 552, the main body 550 and the second top column 54 adopt an integrated structure, and the third top column 553 and the conical head 554 adopt an integrated structure;

[0095] Furthermore, the number of the claws 552 is 12-16, that is, it cannot be too few, which will affect the uniformity of the force applied on the circumference, nor too many, which will increase the difficulty of processing and affect the connection strength between the claws 552 and the main body 550;

[0096] At the same time, when the claw head 552 is stretched open, if the angle of the master cylinder column piston 6 is not aligned, it will inevitably cause friction between the master cylinder column piston 6 and the conical head 554. Therefore, in order to reduce wear and friction, the surface of the conical head 554 can be provided with a lubricating layer or made of a lubricating material, specifically polytetrafluoroethylene.

[0097] It can be seen from this embodiment that by providing a slide groove 551 in the main body 550, the third top column 553 slides when it abuts against the inner wall of the main cylinder column piston 6 in the axial direction, and simultaneously pushes the plurality of claws 552 to open outward, and when the abutment joint 43 is used to position the main cylinder column piston 6 in the axial direction, radial adjustment and positioning are performed;

[0098] At the same time, the plurality of claws 552 ensure uniformity in the radial direction of the inner wall of the master cylinder column piston 6;

[0099] The setting of the protrusion 555 can increase the degree of expansion of the claw head 552 and ensure the radial adjustment and positioning of the master cylinder column piston 6.

[0100] Embodiment 7:

[0101] This embodiment provides a master cylinder column piston drilling system, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0102] When the clamping jaws 55 clamp the main cylinder column piston 6, the head mechanism 2 is arranged corresponding to the second top column 54;

[0103] The diameter of the cross section of the second top column 54 is much smaller than the diameter of the cross section of the inner chamber of the master cylinder column piston 6 .

[0104] It can be seen from the present embodiment that, when the main cylinder column piston 6 is clamped by the clamping jaws 55, the head mechanism 2 is arranged corresponding to the second top column 54, and the diameter of the cross section of the second top column 54 is much smaller than the diameter of the cross section of the internal chamber of the main cylinder column piston 6, that is, when the drill bit 20 penetrates the main cylinder column piston 6, a sufficient distance is left from the second top column 54, and no damage is caused to the second top column 54 or the clamping jaws 55, thereby avoiding damage and extending the service life.

[0105] Embodiment 8:

[0106] This embodiment provides a master cylinder column piston drilling system, which, in addition to the technical solutions of the above embodiments, also has the following technical features:

[0107] Two bases 3 are provided along the axial direction of the master cylinder column piston 6 , and the clamping mechanism 7 is installed between the two bases 3 .

[0108] It can be seen from this embodiment that the two bases 3 are provided to improve the stability of the pre-support of the master cylinder column piston 6, thereby preventing the angle of the master cylinder column piston 6 from deviating too much from the horizontal direction when it is placed.

[0109] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
