Technical Field

[0001] This invention relates to the field of diesel engine parts processing technology, specifically a drilling device for the production and processing of marine diesel engine parts. Background Technology

[0002] When drilling diesel engine parts using a drilling device, the drilling device needs to first use a clamp to fix the parts. In order to enable the drilling device to fix parts of different shapes without having to remove and replace the clamp, the fixing blocks of the clamp on the drilling device generally have multiple fixing surfaces of different shapes (e.g., circular, flat) to accommodate parts of different shapes (circular, square parts). For example, a drilling device with such a clamp is disclosed in the publication document of CN214134061U, which is a drilling device for manufacturing and processing marine diesel engine parts. However, the device has certain limitations in use. For example, the fixing blocks on both sides need to be adjusted separately (i.e., first flip and adjust one fixing block, then flip and adjust the other fixing block), which is relatively slow and affects the drilling efficiency of the parts. Summary of the Invention

[0003] The purpose of this invention is to provide a drilling device for the production and processing of marine diesel engine parts, so as to solve the problem mentioned in the background art that the fixing blocks on both sides need to be adjusted separately, which is relatively slow.

[0007] Preferably, the rack has a plurality of positioning blocks arranged sequentially along the length of the rack on its sidewall, and the mounting groove has a limiting member for contacting the positioning blocks on its inner sidewall to prevent the rack from moving outward of the mounting groove. The mounting groove has a spring member for pushing the rack outward of the mounting groove.

[0008] Preferably, the limiting member includes a connecting block and a blocking block hinged to the end of the connecting block via an elastic pivot. The blocking block is provided with a limiting ring. The connecting block is slidably provided with a plug for inserting into the limiting ring and an elastic element for supporting the plug. The plug is provided with a movable magnetic block. The connecting block is provided with an electromagnet for repelling the movable magnetic block. The blocking block is provided with a touch switch for controlling the electromagnet to be energized on the side facing the connecting rod.

[0009] Preferably, a telescopic rod is provided between two adjacent positioning blocks.

[0013] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0014] Example 1

[0015] Please see Figure 1 A drilling device for manufacturing and processing marine diesel engine parts includes: a workbench 1, a mounting frame 2 mounted on the top of the workbench 1, a bracket 3 slidably mounted on the mounting frame 2, a drive device mounted on the mounting frame 2 (the drive device includes a motor mounted on the mounting frame 2 and a screw mounted on the output shaft of the motor, the screw passes through the bracket 3, and a screw hole is opened at the connection between the bracket 3 and the screw, the motor is used to make the screw rotate forward or reverse, so as to move the bracket 3 up or down), a drilling assembly 4 (the drilling assembly 4 includes a drive motor and a drill bit mounted on the output shaft of the drive motor), and a processing platform 5 is provided on the top of the workbench 1, the processing platform 5 being located below the drilling assembly 4.

[0016] It should be noted that the top of the processing platform 5 is provided with a storage slot, and an electric telescopic rod is provided in the storage slot. A support block is installed on the moving end of the electric telescopic rod. When the parts to be processed are placed on the processing platform 5, the electric telescopic rod drives the support block to move upward to support the parts. The top wall of the support block is provided with holes to collect the waste generated during drilling.

[0017] Please see Figure 1 and Figure 2The top left and right sides of the processing platform 5 are slidably provided with supports 8. The processing platform 5 is provided with a driving component (electric telescopic rod, the moving end of the electric telescopic rod is connected to the support 8, and the support 8 is moved by the electric telescopic rod, so that the two supports 8 move closer to each other or further apart). The top of the support 8 is provided with a rotating rod 6 (the rotating rod 6 is set vertically). Several fixing blocks 7 are provided on the outer wall of the rotating rod 6. The fixing blocks 7 are arranged in a ring on the outer wall of the rotating rod 6. The side wall of the fixing block 7 away from the rotating rod 6 is flat, arc-shaped or other shapes.

[0018] Please see Figure 1 The support 8 is equipped with a drive assembly. Please refer to Figure 1 ,read Figure 2 and Figure 3 The support 8 has a mounting groove, and the bottom end of the rotating rod 6 extends into the inner cavity of the mounting groove. A gear ring 11 is fixedly sleeved on the outer wall of the rotating rod 6, and the gear ring 11 is located in the inner cavity of the mounting groove. The drive assembly includes two racks 10, which are slidably inserted into two mounting grooves respectively (according to...). Figure 2 In the direction shown, the rack 10 can slide back and forth in the mounting groove. The two racks 10 mesh with the two gear rings 11 respectively (the two racks 10 are located on the outside of the two gear rings 11, according to...). Figure 2 As shown, when the connecting rod 9 moves backward, both racks 10 move backward simultaneously, causing the left gear ring 11 to rotate clockwise and the right gear ring 11 to rotate counterclockwise; when the connecting rod 9 moves forward, both racks 10 move forward simultaneously, causing the left gear ring 11 to rotate counterclockwise and the right gear ring 11 to rotate clockwise), a connecting rod 9 is provided between the two racks 10.

[0019] Working principle: Move the connecting rod 9 backward or forward to make the two racks 10 move backward or forward synchronously, and make the two rotating rods 6 rotate synchronously, which in turn rotates several fixed blocks 7. Depending on the shape of the part to be processed, rotate the fixed block 7 that matches it to a predetermined area (that is, make the two fixed blocks 7 that need to be used face each other). Then the driving component drives the two supports 8 to move closer to each other until the two fixed blocks 7 clamp the part. Use the drilling assembly 4 to drill holes in the part. After drilling is completed, the drilling assembly 4 and the supports 8 are reset.

[0020] It should be noted that the fixing block 7 and the rotating rod 6 are detachably connected, such as by bolts, so that the fixing block 7 can be removed from the outer wall of the rotating rod 6 for replacement.

[0021] In this embodiment, as a further optimization, please refer to... Figure 1 and Figure 2Link 9 is a telescopic link, which includes a telescopic main rod and a telescopic secondary rod that slides inside the telescopic main rod. When the two supports 8 move closer or further apart, the two racks 10 also move closer or further apart. At this time, the telescopic secondary rod will slide in the inner cavity of the telescopic main rod, causing the length of link 9 to change in order to adapt to the change in the distance between the two supports 8, without affecting the movement of the supports 8.

[0022] In this embodiment, as a further optimization, please refer to... Figure 3 , Figure 4 and Figure 5 The rack 10 has several positioning blocks 16 on its side wall. The positioning blocks 16 are arranged in sequence along the length extension direction of the rack 10. The inner side wall of the mounting groove is provided with a limiting member 13. A spring member 12 (spring) is provided between the mounting groove and the rack 10. Please refer to Figure 4 and Figure 5The limiting member 13 includes a connecting block 131 and a blocking block 132 hinged to the end of the connecting block 131 via an elastic rotating shaft (the elastic rotating shaft includes a rotating shaft and a torsion spring; the connecting block 131 is connected to the blocking block 132 via the rotating shaft, and the two ends of the torsion spring are connected to the connecting block 131 and the blocking block 132 respectively; the torsion spring allows the blocking block 132 to return to its original position after rotation). The end of the connecting block 131 away from the blocking block 132 is connected to the inner wall of the mounting groove. The blocking block 132 is provided with a limiting ring 135, and an insert 134 is slidably provided on the connecting block 131. The insert 134 is inserted into the limiting ring. Inside ring 135 (to prevent the blocking block 132 from rotating), an elastic element 136 (spring) is provided between connecting block 131 and insert block 134. Insert block 134 has a movable magnetic block 137 (magnetic block). Connecting block 131 has an electromagnet 138. The electromagnet 138 and movable magnetic block 137 have the same magnetic poles on their sides (resisting force will be generated between them). The blocking block 132 has a touch switch 133 on the side facing connecting rod 9. The touch switch 133 is connected in series with electromagnet 138 and power supply via a wire (used to control the energization of electromagnet 138). When it is necessary to rotate the two fixing blocks 7 to their relative positions, the connecting rod 9 is moved backward, causing the rack 10 to move backward until the positioning block 16 contacts the blocking block 132. The touch switch 133 is then pressed to power the electromagnet 138. When energized, the electromagnet 138 generates magnetic force to repel the moving magnetic block 137, causing it to move along with the insert block 134 out of the limiting ring 135, releasing the restriction on the blocking block 132. As the rack 10 continues to move backward, the positioning block 16 pushes the blocking block 132 to rotate until the positioning block 16... After passing the blocking block 132, the blocking block 132 resets under the action of the elastic rotating shaft. At the same time, the pressing action of the positioning block 16 on the touch switch 133 disappears, de-energizing the electromagnet 138. Under the action of the elastic element 136, the insert block 134 moves and resets, re-inserting into the limiting ring 135, thus limiting the blocking block 132 again (preventing its rotation). As the rack 10 moves backward, the spring element 12 is compressed. Therefore, the spring element 12 provides a forward force to the rack 10, causing the positioning block 16 to contact the blocking block 132 (according to...). Figure 2As shown, the positioning block 16 moves behind the blocking block 132. Due to the blocking effect of the blocking block 132, the positioning block 16 cannot move forward, thus fixing the rack 10. When the rack 10 moves backward, the positioning block 16 presses the touch switch 133, turning on the power to the electromagnet 138. It takes a certain amount of time for the insert block 134 to move out of the limit ring 135. During this time, the rack 10 cannot move backward (the operator can feel obvious resistance). After a certain amount of time (i.e., the insert block 134 moves out of the limit ring 135), the rack 10 can continue to move backward. When the operator feels the rack 10 being obstructed and then breaks through the obstruction, the rack 10 stops. At this time, one fixing block 7 has moved to the fixed area. By repeating the operation, the operator can move the other fixing blocks 7 to the fixed area in sequence, making the adjustment of the fixing blocks 7 more precise and faster.

[0023] It should be noted that the number of positioning blocks 16 is the same as the number of fixing blocks 7. When the second positioning block 16 moves to the rear side of the blocking block 132, the next fixing block 7 moves to the fixing area. A switch is provided on the outside of the support 8 to control the electromagnet 138 to be energized, thereby releasing the restriction on the blocking block 132 and allowing the rack 10 to be reset.

[0024] In this embodiment, as a further optimization, please refer to... Figure 4 A telescopic rod 15 is provided between two adjacent positioning blocks 16. The telescopic rod 15 includes a telescopic main rod, a telescopic secondary rod, and a bolt. The telescopic secondary rod is slidably inserted into the inner cavity of the telescopic main rod, and the bolt is screwed onto the outer wall of the telescopic main rod to fix the telescopic secondary rod. The distance between adjacent positioning blocks 16 can be adjusted by telescopically extending and retracting the telescopic rod 15.

[0025] It should be noted that only one of the positioning blocks 16 is connected to the rack 10, while the other positioning blocks 16 are not connected to the rack 10.

[0026] In this embodiment, as a further optimization, please refer to... Figure 2 and Figure 6 The top of the processing platform 5 is provided with a slot 17, and a movable plate 18 is slidably provided in the slot 17 (the movable plate 18 can move up and down in the slot 17). An elastic element (spring) is installed between the slot 17 and the movable plate 18. A limiting block 14 is provided on the top of the movable plate 18. The limiting block 14 contacts the teeth of the rack 10 to prevent the rack 10 from moving. An opening is provided on the top of the rack 10, and a pressure rod 19 (the pressure rod 19 can move up and down) is slidably inserted into the opening. The bottom end of the pressure rod 19 is in contact with the top wall of the movable plate 18. The limiting block 14 is used to fix the rack 10 so that it will not move automatically, ensuring that the positioning block 16 stably fixes the parts. When it is necessary to move the rack 10, the pressure rod 19 is pushed down to push the movable plate 18 down, so that the limiting block 14 does not contact the rack 10, and the restriction on the rack 10 is released.

[0027] In this embodiment, as a further optimization, please refer to... Figure 6 and Figure 7 The limiting block 14 includes a mounting block 141, which is mounted on the top of the moving plate 18. A moving groove is formed on the side of the mounting block 141 facing the rack 10, and a moving block 142 slides within the moving groove. An elastic block 143 (made of rubber) is provided on the side of the moving block 142 facing the rack 10. A support block 20 is provided on the side wall of the support 8, positioned between the elastic block 143 and the mounting block 141. When the moving plate 18 moves upward and resets with the limiting block 14, the support block 20 inserts between the elastic block 143 and the mounting block 141, pushing the elastic block 143 towards the rack 10, increasing the contact pressure between the two, and making the limiting block 14 more stable in restricting the rack 10, thus preventing accidental movement of the rack 10. Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
