Description

However, due to the influence of various factors, such as uneven hardness of the workpiece material, drill bit wear, insufficient machine tool accuracy, improper operation, etc., the drilling process often deviates, resulting in inaccurate drilling position, different hole sizes, poor hole wall quality and other problems.

DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] The embodiments of the present application solve the problems in the prior art by providing an anti-deviation structure for mechanical drilling.

[0037] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0038] Embodiment 1:

[0039] The specific structure of this embodiment is as follows: Figure 1-Figure 9 As shown, a mechanical drilling anti-deviation structure comprises: a support frame 1 and a fixed frame 2, the left and right sides of the support frame 1 are provided with limit slots 3, the top of the fixed frame 2 is fixedly connected with a connecting plate 4, the top of the connecting plate 4 is fixedly connected with a cylinder 5, the left and right sides of the fixed frame 2 are fixedly connected with limit blocks 6, and the adjacent two sides of the fixed frame 2 are provided with slide slots 7; through the design of the support frame 1, the fixed frame 2 and the buffer plate 40, the stability and vibration resistance of the whole system during the drilling process are ensured, and the system can remain stable even under high-speed operation or complex working conditions, thereby ensuring the drilling quality;

[0040] The displacement assembly includes a first electric push rod 8 and a second electric push rod 9 fixedly connected to the fixed frame 2, the telescopic ends of the first electric push rod 8 and the second electric push rod 9 are fixedly connected to a moving rod 10, the adjacent two ends of the two moving rods 10 are fixedly connected to a slider 11, the tops of the other two adjacent ends of the two moving rods 10 are fixedly connected to a laser sensor 12, and the two moving rods 10 are provided with a fixing groove 13;

[0041] The installation assembly includes a connecting block 14 that penetrates and slides in two fixed grooves 13, a limiting sleeve 15 is connected to the outer surface of the connecting block 14, and the connecting block 14 abuts against the bottom of the moving rod 10 located below. The front and rear sides of the connecting block 14 are provided with a card slot 16, and the card slots 16 are fixedly connected with elastic telescopic rods 17, and the ends of the two elastic telescopic rods 17 that are far away from each other are fixedly connected with a card block 18;

[0042] The moving component includes a connecting frame 19 fixedly connected to the bottom end of the connecting block 14, a dual-axis motor 20 is fixedly connected inside the connecting frame 19, and the upper and lower ends of the dual-axis motor 20 are fixedly connected to a rotating shaft 21, a reciprocating screw 22 is fixedly connected to the outside of the rotating shaft 21 located at the top, a moving column 23 is slidably connected to the outside of the reciprocating screw 22, a fixed rod 24 is fixedly connected to the front end of the moving column 23, and a cam 25 is fixedly connected to the top of the rotating shaft 21 located at the top; through this horizontal and vertical setting, the drill bit 34 can move in two mutually perpendicular planes, thereby realizing multi-dimensional position adjustment.

[0043] When the position of the drill bit 34 needs to be adjusted, the controller 41 will control the extension and retraction of the first electric push rod 8 and the second electric push rod 9 separately or simultaneously according to the data provided by the laser sensor 12 to achieve precise movement in the horizontal and vertical directions. This design enables the drill bit 34 to adapt to the drilling requirements of different angles and positions;

[0044] The blowing assembly includes two piston cylinders 26 fixedly connected to the bottom of the connecting frame 19, and piston rods 27 are slidably connected to the two piston cylinders 26. Push plates 28 are fixedly connected to the two ends of the two piston rods 27. The push plates 28 and the two sides of the piston cylinders 26 are fixedly connected to the same first spring 29. The first spring 29 is sleeved on the outside of the corresponding piston rod 27. A one-way air inlet is provided on the outside of the piston cylinder 26, and two fixed pipes 30 are connected to the outside of the piston cylinder 26.

[0045] In some examples, the bottom of the connecting frame 19 is fixedly connected to a cooling box 31, the bottom of the cooling box 31 is connected to a pressing nozzle 32, a coolant is provided in the cooling box 31, and the bottom end of the fixing rod 24 abuts against the bottom of the pressing nozzle 32. By continuously spraying the coolant, the temperature of the drill bit 34 and the motor can be effectively reduced, and the metal fatigue and wear caused by high temperature can be reduced. The lubricating effect of the coolant can also reduce the friction between the drill bit 34 and the workpiece, and further reduce the wear rate. In the long run, this efficient heat dissipation method can significantly extend the service life of the drill bit 34, reduce the frequency and cost of replacing the drill bit 34, and also help maintain the accuracy of the workpiece size and prevent deformation caused by thermal expansion. At the same time, the coolant can also remove the chips generated during the drilling process and keep the working area clean.

[0046] In some examples, the fixing rod 24 is L-shaped, and the fixing rod 24 is slidably connected to the connecting frame 19. The bottom end of the rotating shaft 21 below is fixedly connected to a support plate 33, and a drill bit 34 is clamped in the support plate 33. The bottom end of the support plate 33 is fixedly connected to a second spring 35, and the bottom end of the second spring 35 is fixedly connected to a fixing sleeve 36, which is sleeved on the outside of the drill bit 34.

[0047] In some examples, two cross grooves 37 are provided in the connecting frame 19. By providing the two cross grooves 37, the cross rod 38 is prevented from being offset and stuck during the reciprocating sliding process, thereby ensuring the stable movement of the cross rod 38.

[0048] A cross rod 38 is slidably connected through the two cross grooves 37, and the two cross rods 38 are respectively abutted against the left and right sides of the cam 25. A plurality of one-way air outlets are provided outside the fixed pipe 30, and the bottom ends of the two cross rods 38 are respectively abutted against the left and right sides of the two push plates 28. The design of the one-way air inlet and outlet optimizes the flow direction of the airflow and further improves the drilling efficiency.

[0049] In some examples, the first electric push rod 8 and the second electric push rod 9 are arranged horizontally and vertically, the two moving rods 10 are arranged horizontally and vertically, and the slider 11 is slidably connected in the corresponding slide groove 7. By setting the slide groove 7, the slide groove 7 and the slider 11 cooperate with each other, so that the two moving rods 10 can be prevented from being offset and misaligned during the movement process, thereby ensuring the stability of the movement of the two moving rods 10;

[0050] The limiting sleeve 15 abuts against the top of the upper moving rod 10, the clamping block 18 abuts against the top of the limiting sleeve 15, the top of the clamping block 18 is provided with a handle 39, and the limiting block 6 is slidably connected in the corresponding limiting groove 3. By setting the limiting groove 3, the limiting groove 3 and the limiting block 6 cooperate with each other, which can avoid the misalignment of the fixing frame 2 during movement, thereby ensuring the stable movement of the fixing frame 2;

[0051] The top of the cylinder 5 is fixedly connected in the support frame 1 , and buffer plates 40 are provided at both bottom ends of the support frame 1 .

[0052] In some examples, a controller 41 is fixedly connected to the top of the fixed frame 2, the output ends of the two laser sensors 12 are electrically connected to the input ends of the controller 41, the control ends of the first electric push rod 8 and the second electric push rod 9 are electrically connected to the output ends of the controller 41, and the power input ends of the first electric push rod 8 and the second electric push rod 9 and the laser sensor 12 are electrically connected to an external power supply.

[0053] The laser sensor 12 is used to monitor the position of the drill bit 34 in real time, and it sends the detected position data to the controller 41. The high precision of the laser sensor 12 ensures the accuracy of the position during the drilling process, thereby reducing human errors. The first electric push rod 8 and the second electric push rod 9 are extended and retracted according to the instructions of the controller 41 to adjust the position of the drill bit 34. The precise control of the first electric push rod 8 and the second electric push rod 9 enables the drill bit 34 to move quickly and accurately to the predetermined position without manual adjustment;

[0054] Due to the coordinated work of the controller 41, the laser sensor 12 and the electric push rod, the operator does not need to frequently check and adjust the position of the drill bit 34. This reduces the labor intensity of the operator and also reduces the risk caused by improper human operation. The automated control makes the drilling process faster and more reliable, reduces downtime, and improves the continuous operation capability of the production line.

[0055] The working principle of the present invention is:

[0056] When using the device, first place the device in a suitable position, then insert the connecting block 14 into the fixing grooves 13 in the two moving rods 10, then put the limiting sleeve 15 outside the connecting block 14, thereby compressing the two clamping blocks 18 and the elastic telescopic rod 17, and then after passing through the limiting sleeve 15, the clamping block 18 returns to its original state under the action of the elastic force of the elastic telescopic rod 17 itself, thereby completing the fixed support of the connecting block 14;

[0057] Then, a coordinate is provided according to the position of the hole to be drilled, and then the two laser sensors 12 start working, emitting laser beams and receiving reflected signals, calculating the distance between the fixed frame 2 and the sensor in the two horizontal directions, and then the controller 41 receives the distance data from the two laser sensors 12 and processes it according to the preset program. According to the processed distance data, control signals are sent to the first electric push rod 8 and the second electric push rod 9 respectively. After receiving the control signal, the first electric push rod 8 and the second electric push rod 9 start to perform the telescopic action. During the execution of the action by the first electric push rod 8 and the second electric push rod 9, the laser sensor 12 monitors the distance between the target object and the sensor in real time. When the distance reaches the preset value, the controller 41 will send a stop signal, and the first electric push rod 8 and the second electric push rod 9 will stop moving. If the distance changes, the controller 41 will adjust the telescopic amount of the first electric push rod 8 and the second electric push rod 9 according to the new distance data until a stable state is reached. The above process is repeated continuously to ensure that the first electric push rod 8 and the second electric push rod 9 are always accurately adjusted according to the position of the target object;

[0058] The first electric push rod 8 and the second electric push rod 9 can respectively push the two moving rods 10 and the slider 11 to slide in the slide groove 7 until they slide to appropriate positions, and drive the connecting block 14 and the limiting sleeve 15 to move synchronously in the two fixed grooves 13. The final intersection position of the two moving rods 10 is the position of the connecting block 14 and the limiting sleeve 15.

[0059] Then, the dual-axis motor 20 is started, and the dual-axis motor 20 can drive the two rotating shafts 21 to rotate synchronously. The rotating shaft 21 located at the top can drive the reciprocating screw 22 and the cam 25 to rotate continuously. When the reciprocating screw 22 rotates, it can drive the moving column 23 and the fixed rod 24 to move up and down in the connecting frame 19, and intermittently squeeze and press the nozzle 32, so that the coolant is sprayed onto the blade of the drill bit 34 and the hot zone of the motor. When the coolant contacts the high-temperature area, it will quickly absorb heat and evaporate, thereby taking away a large amount of heat energy;

[0060] When the cam 25 rotates, it can intermittently hit the two cross rods 38, so that the two cross rods 38 can slide relatively in the two cross grooves 37 and squeeze the two push plates 28, and the push plates 28 can squeeze the two piston rods 27 to move in the piston cylinder 26, so that the air in the piston cylinder 26 can be squeezed out through the one-way air outlet in the fixed pipe 30, so that the motor can be intermittently blown, and then the push plate 28 can drive the piston rod to restore its original state under the action of the elastic force of the first spring 29 itself, and the rotating shaft 21 located below can drive the support plate 33, the second spring 35, the fixed sleeve 36 and the drill bit 34 to rotate continuously;

[0061] Then the cylinder 5 can be started, and the cylinder 5 pushes the connecting plate 4 and the fixing frame 2 to move downward synchronously, and drives the two limit blocks 6 to slide downward in the two limit grooves 3, and drives the first electric push rod 8, the second electric push rod 9 and the two moving rods 10 to move downward synchronously, so that the connecting block 14 and the limit sleeve 15 can drive the connecting frame 19, the dual-axis motor 20 and the piston cylinder 26 to move synchronously, so that the drill bit 34 can move downward for drilling processing. When drilling, when the drill bit 34 penetrates into the workpiece, the fixing sleeve 36 can squeeze the spring upward, so that the drill bit 34 can continue to enter the workpiece, and the drilling processing can be completed.

[0062] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
