Description

Technical Field

[0001] The utility model belongs to the technical field of profile processing, in particular to a multi-row parallel drilling and tapping tool. Background Art

[0002] Suspended seats and handrails on rail transit vehicles are crucial for passenger safety and comfort. These devices typically consist of profiles with multiple fixing holes. These holes must be drilled precisely in the baseplate to facilitate the fastening of bolts or screws during installation. A tapping machine uses a drill bit driven by a high-speed rotation to drill or tap profiles. After the profile is secured with a clamping fixture, the tapping machine performs the drilling or tapping.

[0003] Existing tapping machines can only drill a single hole at a time, which means that when processing profile holes in batches, operators must perform multiple clamping and disassembly. Since only one hole can be drilled at a time, operators need to repeat the positioning, clamping and drilling steps, making the entire processing process very lengthy. When multiple holes need to be drilled in batches of profiles, the processing time increases significantly, affecting production efficiency. During multiple clamping and disassembly processes, the position of the base plate is prone to slight deviations, resulting in errors in the drilling position. This error accumulates in multiple holes and may affect the installation accuracy of the suspension seat and handrails, thereby affecting the safety and comfort of passengers. Utility Model Content

[0004] The purpose of the utility model is to provide a multi-row parallel drilling and tapping tool to solve the problems raised in the above-mentioned prior art.

[0005] Provided is a multi-row parallel drilling and tapping tool, comprising:

[0006] An upper mold, wherein the upper mold is provided with a plurality of through holes distributed in a matrix;

[0007] A plurality of drilling tools, wherein the plurality of drilling tools are disposed in corresponding through holes;

[0008] A lower die, used for positioning the profile;

[0009] A horizontal transfer mechanism, which is used to drive the upper mold or the lower mold to move in the horizontal direction;

[0010] The vertical transfer mechanism is used to drive the upper mold or the lower mold to move in the vertical direction.

[0011] The drill tool further comprises a drive mechanism, a drill sleeve, a drill chuck, and a tool. The drill sleeve is positioned within a through-hole, and the drill chuck is rotatably connected to the drill sleeve. The drive mechanism drives the tool through the drill chuck. The drill sleeve and the upper die are secured via the through-hole to stabilize the drill tool and prevent significant vibration and deflection during drilling or tapping. The drill sleeve acts as a transmission structure, transmitting the drive mechanism's torque to the tool, enabling high-speed rotation.

[0012] Furthermore, the drill chuck is connected to the drive mechanism via a universal coupling. Since it is difficult to align the output shaft of the drive mechanism and the tool coaxially during assembly, the universal coupling can realize eccentric transmission between the output shaft of the drive mechanism and the tool.

[0013] Furthermore, the drill chuck and the tool are detachably connected, and tools of different types can be replaced on the drill chuck to process holes of different diameters and patterns.

[0014] Furthermore, the lower die includes a base, a baffle, and an actuator. The actuator's cylinder is fixedly connected to the base, and the baffle is fixedly connected to the base and arranged opposite the actuator's output shaft. After the profile is placed on the base, the actuator can push the profile to the baffle and clamp it, limiting the profile and preventing it from shifting during drilling.

[0015] Furthermore, the apparatus further comprises a coolant supply assembly, which includes a distribution valve and a plurality of coolant nozzles, wherein the plurality of coolant nozzles are connected to the distribution valve. The distribution valve distributes coolant proportionally to each coolant nozzle, and the coolant nozzles spray the coolant toward the drilling point to cool the drilling tool.

[0016] Furthermore, the distribution valve is connected to the coolant nozzle via a hose, which can be used to adjust the position of the coolant nozzle and shape it so that the coolant is at an optimal spray angle.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] When drilling or tapping a profile, the upper and lower dies adjust their relative positions via a horizontal transfer mechanism to align the drill tool with the hole to be processed. A vertical transfer mechanism brings the drill tool into contact with the profile, enabling automated positioning and processing, freeing up manpower and improving machining accuracy. Multiple drill tools on the upper die can simultaneously drill and tap multiple corresponding holes in the profile, significantly improving machining efficiency, eliminating drilling errors, and enhancing machining accuracy.

It should be understood that the specific embodiments described herein are merely used to explain this application and are not intended to limit this application.

[0025] However, unnecessary detailed descriptions may be omitted.

Furthermore, the drawings and the following description are provided to facilitate a thorough understanding of this application by those skilled in the art and are not intended to limit the subject matter recited in the claims.

[0026] See also Figure 1-2 As shown, in an embodiment of the present invention, a multi-row parallel drilling and tapping tool comprises an upper die 1, a plurality of drilling tools 2, a lower die 3, a horizontal transfer mechanism 4, and a vertical transfer mechanism 5. The upper die 1 is provided with a plurality of through holes 11 distributed in a matrix. The plurality of drilling tools 2 are arranged in the corresponding through holes 11. The lower die 3 is used to position the profile. The horizontal transfer mechanism 4 is used to drive the upper die 1 or the lower die 3 to move in the horizontal direction. The vertical transfer mechanism 5 is used to drive the upper die 1 or the lower die 3 to move in the vertical direction.

[0027] When machining a profile, the profile is placed on the lower die 3. The horizontal transfer mechanism 4 and the vertical transfer mechanism 5 push the upper and lower dies 1 and 3 to align each drill 2 with the hole positions to be machined on the profile. The drill 2 is then activated to drill the profile. The drill 2 can be arranged in a single row on the upper die 1. After machining one row of holes on the profile, the lower die 3 is moved by the horizontal transfer mechanism 4 to align the drill 2 with the next row of holes for machining. Alternatively, the drill 2 can be arranged in multiple rows and multiple points, allowing all holes on the profile to be machined at once. The arrangement of the drill 2 on the upper die 1 can be selected based on the actual drilling needs of the profile.

[0028] Both the horizontal transfer mechanism 4 and the vertical transfer mechanism 5 are driven by a transmission structure such as guide rails, telescopic cylinders, and drive wheels. This is prior art, and the specific structure will not be described in detail here. The arrangement between the horizontal transfer mechanism 4 and the vertical transfer mechanism 5 and the upper mold 1 and the lower mold 3 can be adjusted according to actual needs.

[0029] In one specific embodiment, the horizontal transfer mechanism 4 is connected to the lower mold 3 and is used to drive the lower mold 3 to move horizontally, while the vertical transfer mechanism 5 is connected to the upper mold 1 and is used to drive the upper mold 1 to move vertically. The profile is placed on the lower mold 3 and fixed. The horizontal transfer mechanism 4 pushes the lower mold 3 toward the upper mold 1, aligning the holes to be processed on the profile with the various drill tools 2 on the upper mold 1. The vertical transfer mechanism 5 then drives the upper mold 1 downward to bring the drill tools 2 into contact with the processing holes. At the same time, the drill tools 2 start to drill the various holes. As the vertical transfer mechanism 5 drives the upper mold 1 to gradually move downward, the drill tools 2 gradually penetrate into the interior of the profile.

[0030] Specifically, the drill tool 2 includes a drive mechanism 21, a drill sleeve 22, a drill chuck 23, and a cutter 24. The drill sleeve 22 cooperates with the through-hole 11 to secure the drill tool 2 to the upper die 1. The drill sleeve 22 and drill chuck 23 are rotationally connected, perhaps via bearings. The cutter 24 is secured within the drill chuck 23, which transmits torque to the cutter 24.

[0031] In one embodiment, each drill chuck 23 is driven by a drive mechanism 21. The cylinder of the drive mechanism 21 is fixed to a structure that moves synchronously with the upper die 1. The output shaft of the drive mechanism 21 drives the drill chuck 23 to rotate, and then drives the tool 24 to rotate through the drill chuck 23.

[0032] In one embodiment, multiple drill chucks 23 are driven by a drive mechanism 21. The cylinder of the drive mechanism 21 is fixed to a structure that moves synchronously with the upper mold 1. The drive mechanism 21 transmits torque to the multiple drill chucks 23 simultaneously through a gear or belt transmission structure, thereby driving the tool 24 to rotate through the drill chuck 23.

[0033] The tool 24 is detachably connected to the drill chuck 23. The drill chuck 23 consists of a drill sleeve, a tensioning ring, a connecting block, and a rear cover. Rotating the tensioning ring adjusts the clamping tension of the drill sleeve, thereby clamping and releasing the tool 24. The tension adjustment mechanism of the drill chuck 23 is well known in the art, and its detailed structure will not be described in detail here. The detachable structure between the drill chuck 23 and the tool 24 allows for replacement of different tool types, allowing for drilling of mounting holes or threaded holes of varying diameters and textures.

[0034] Furthermore, the drill chuck 23 is connected to the drive mechanism 21 via a universal coupling 25. The universal coupling 25 is capable of transmitting torque between different axes. If there is an assembly angle error or axis misalignment between the drill chuck 23 and the output shaft of the drive mechanism 21, or between the drill chuck 23 and the transmission structure that transmits the drive mechanism 21's torque, the universal coupling 25 can effectively compensate for such errors, ensuring the transmission of power.

[0035] The lower die 3 comprises a base 31, a baffle 32, and an actuator 33. The base 31 supports the profile and cooperates with the horizontal transfer mechanism 4 to generate horizontal movement. When the profile is placed on the base 31, the piston rod of the actuator 33 pushes the profile toward the baffle 32, ultimately clamping the profile between the baffle 32 and the actuator 33. This secures and positions the profile, preventing vibration and displacement during drilling, which could lead to deviations in drilling accuracy. The actuator 33 can be a pneumatic, electric, or hydraulic cylinder.

[0036] When tool 24 is drilling, a significant amount of heat is generated between tool 24 and the profile. To prevent the high temperature from affecting tool 24 and the hole, the drilling area needs to be cooled. Therefore, the tapping tool also includes a coolant supply assembly 6, which includes a distribution valve 61 and several coolant nozzles 62. Coolant is supplied to distribution valve 61, which evenly distributes the coolant to each coolant nozzle 62, and then sprays the coolant through the coolant nozzles 62 toward the drilling area, thereby cooling the drilling area.

[0037] Furthermore, the distribution valve 61 is connected to the coolant nozzle 62 via a hose 63. Hose 63 is capable of twisting freely and retaining its shape. This allows the coolant nozzle 62 to be adjusted to any position and spray angle, ensuring that the coolant sprayed from the coolant nozzle 62 completely covers the area to be cooled.

[0038] It should be noted that the present application is not limited to the above-mentioned embodiments. The above-mentioned embodiments are merely examples, and any embodiments having substantially the same structure and effect as the technical concept within the scope of the present application are all included in the technical scope of the present application. In addition, without departing from the scope of the present application, any other embodiments that can be conceived by those skilled in the art and that combine some of the constituent elements in the embodiments are also included in the scope of the present application.
