Description

Technical Field

[0001] The present application relates to the technical field of machine tool drilling equipment, and in particular to a clamping positioning drilling device and a machine tool. Background Art

[0002] At present, in the field of machining, especially in drilling operations for workpieces made of metal, plastic, wood and other materials, accurate and stable positioning is the key to ensuring machining quality and efficiency. Traditional drilling processes usually rely on a fixed drill stand to push the workpiece close to the drill bit to achieve hole drilling. However, if the workpiece is only driven by the driving force, it will cause one side of the workpiece to tilt or other deviations during drilling or milling, resulting in inaccurate hole drilling. Therefore, a clamping assembly is usually installed on the fixed drill stand during drilling or milling to stabilize the workpiece. However, during the movement of the workpiece, the clamping assembly is prone to relative movement with the workpiece, scratching the workpiece surface, resulting in indentations or scratches on the workpiece surface, affecting the quality of the finished workpiece. Summary of the invention

[0003] In order to reduce the impact on the quality of the finished workpiece during the drilling process, the present application provides a clamping positioning drilling device and a machine tool.

[0004] In the first aspect, the present application provides a clamping positioning drilling device, which adopts the following technical solution:

[0005] A clamping and positioning drilling device comprises: a drill frame and a drilling mechanism, wherein the drill frame is arranged on a machine tool, and the drilling mechanism is arranged on the drill frame and is located at the front side of the workpiece moving direction; and further comprises a clamping and positioning mechanism, wherein the clamping and positioning mechanism comprises:

[0006] A sliding frame, sliding on the drilling frame;

[0007] An elastic clamping member is arranged on the sliding frame, can abut against the workpiece and press the workpiece against the machine tool, and can be deformed so that one end thereof away from the workpiece can be relatively displaced with the workpiece;

[0008] A driving member is arranged on the drilling frame and connected to the sliding frame, and is used for driving the sliding frame to slide.

[0009] By adopting the above technical solution, when positioning the workpiece for drilling, the workpiece is first placed on the processing surface of the machine tool, the sliding frame is driven by the driving member to approach the workpiece, the elastic clamping member abuts against the workpiece, and continues to approach the workpiece so that the workpiece fits the processing surface, and then the drilling mechanism is used to drill holes or mill grooves in the workpiece, and during the drilling or milling process, the workpiece is pushed to slide, and the elastic clamping member is deformed.

[0010] Traditional drilling or milling devices often use rigid clamping mechanisms, such as fixtures or chucks, which use mechanical force to firmly fix the workpiece in a certain position; the present technical solution uses elastic clamping parts. This clamping method allows the workpiece to be elastically deformed when it is moved by external force, thereby reducing damage and indentation to the workpiece. Since the design of the elastic clamping parts reduces damage to the workpiece, it also reduces downtime and maintenance costs caused by workpiece damage, and reduces the impact on the workpiece processing quality during the drilling or milling process; traditional clamping mechanisms are usually fixed, and the workpiece needs to be moved to the bottom of the clamping mechanism for positioning; in the present technical solution, the sliding frame can slide on the drilling frame and is driven by the driving member. This design enables the clamping and positioning mechanism to flexibly adapt to workpieces of different sizes and changes in the position of the workpiece during transportation. For example, when the workpiece is thin, it is easy to jump during the drilling process. The clamping force can be appropriately adjusted through the driving member to allow the workpiece to slide stably.

[0011] Optionally, the sliding frame is arranged around the drilling mechanism, and the elastic clamping member is arranged on the sliding frame around the drilling mechanism to form a working cavity.

[0012] By adopting the above technical solution, when the driving member drives the sliding frame to approach the workpiece, the elastic clamping member abuts against the workpiece. The elastic clamping member is arranged around the drilling mechanism and the drilling position, and the surrounding sides of the drilling position are clamped and fixed at the same time, so that the workpiece is more stable during drilling, and the shaking of the workpiece is further reduced, so that the processing quality of the workpiece can be maintained and the damage to the workpiece is reduced.

[0013] Optionally, the elastic clamping member extends in a direction away from the sliding frame, and an end portion thereof abuts against a workpiece, and the elastic clamping member can be bent in a width direction thereof.

[0014] By adopting the above technical solution, when the workpiece moves, an extrusion force is applied to the workpiece in the length direction, and the movement along the width direction makes the elastic clamp easier to bend, reduces excessive application of driving force, reduces resource waste, and at the same time can maintain pressure on the workpiece.

[0015] Optionally, the elastic clamping member is a brush, and the brush is in a cluster shape.

[0016] By adopting the above technical solution and setting the brush, the density of the elastic clamp can be increased, making the working chamber more closed, effectively reducing the splash of debris generated by drilling, maintaining a relatively hygienic working environment, reducing physical damage to workers, and reducing environmental pollution.

[0017] Optionally, a dust suction mechanism is provided on the sliding frame, and the dust suction mechanism is used to absorb debris at the elastic clamping member.

[0018] By adopting the above technical solution, during the drilling process, the dust suction mechanism extracts the debris in the working chamber by evacuating air from the working chamber, thereby reducing the accumulation of debris at the drilling position and reducing the impact on drilling, so that the drilling quality can be maintained, and then the processing quality of the workpiece can be maintained. At the same time, the setting of the brush facilitates the entry of external air, making the extraction of debris more convenient, and can minimize the splashing and overflow of debris, further maintaining a clean and hygienic working environment.

[0019] Optionally, the sliding frame is provided with an adjustment mechanism, and the adjustment mechanism comprises:

[0020] A slide block slides on the slide frame in a direction close to the workpiece and is connected to the elastic clamping member;

[0021] The sliding assembly is arranged on the sliding frame and connected to the sliding block, and is used to drive the sliding block to approach the workpiece when the workpiece slides, so that the elastic clamping member maintains a vertical pressing force on the workpiece.

[0022] By adopting the above technical solution, during the sliding process of the workpiece, the sliding assembly drives the slider to approach the workpiece, and the slider drives the elastic clamp to apply a squeezing force to the workpiece. At the same time, during the movement of the workpiece, the elastic clamp undergoes elastic bending deformation. Through the setting of the adjustment mechanism, the squeezing force applied by the elastic clamp to the workpiece is maintained, thereby reducing the bounce of the workpiece during the drilling process, maintaining the stability of the drilling work, and reducing damage to the workpiece.

[0023] Optionally, the sliding assembly comprises:

[0024] A driving block slides on the sliding frame and abuts against a side of the sliding block away from the workpiece, and a wedge surface is formed on the abutting surface. When the workpiece slides, the wedge surface drives the sliding block to squeeze the elastic clamping member to press against the workpiece;

[0025] The transmission member is connected with the driving block, contacts with the workpiece and slides along with the workpiece.

[0026] By adopting the above technical solution, during the movement of the workpiece, the driving block is driven to slide through the transmission member, the driving block drives the slider to approach the workpiece, and the slider drives the elastic clamping member to squeeze the workpiece. Through the setting of the above structure, the squeezing force applied to the workpiece can be maintained, so that the workpiece remains stable during the drilling process, and the processing quality of the workpiece can be maintained.

[0027] Optionally, the contact surface between the transmission member and the workpiece is made of soft material.

[0028] By adopting the above technical solution, the contact surface between the transmission member and the workpiece is made of soft material, which can reduce damage to the workpiece and can follow the movement of the workpiece.

[0029] Optionally, the sliding assembly further includes:

[0030] A reset member, disposed on the sliding frame and connected to the driving block, for driving the driving block and the workpiece to move in the opposite direction;

[0031] The limit block is arranged on the sliding frame and located at one side of the driving block, and is used to limit the position of the driving block.

[0032] By adopting the above technical solution, after the drilling of the workpiece is completed, the sliding frame drives the elastic clamping member away from the workpiece. At this time, the transmission member and the elastic clamping member are separated from the workpiece, and the reset member drives the driving block to reset and abut against the limit block, so that the slider is in a free state. When used next time, the elastic clamping member abuts against the workpiece, and can abut against the driving block again as the downward pressing action proceeds, so that the elastic clamping member maintains the squeezing of the workpiece.

[0033] In the second aspect, the present application provides a machine tool, which adopts the following technical solution:

[0034] A machine tool comprises a clamping positioning drilling device, and also comprises: a conveying roller group and a pushing mechanism, wherein the conveying roller group cooperates with an elastic clamping piece of the clamping positioning drilling device to squeeze a workpiece, and the pushing mechanism is used to push the workpiece to slide in a plane.

[0035] By adopting the above technical solution, when drilling a workpiece, the workpiece is first placed on the conveying roller group, and the conveying roller group conveys the workpiece to the bottom of the elastic clamping member. The elastic clamping member and the conveying roller group cooperate to clamp the workpiece, and then the workpiece is driven to move by the pushing mechanism, and the drilling mechanism drills the workpiece. The elastic clamping member and the conveying roller group cooperate to reduce the probability of the workpiece jumping or tilting, so that the processing of the workpiece remains stable, the damage to the workpiece is reduced, and the movement of the workpiece is maintained.

[0036] In summary, the present application includes at least one of the following beneficial technical effects:

[0037] 1. This technical solution adopts an elastic clamping member. This clamping method allows the workpiece to be elastically deformed when it is moved by external force, thereby reducing damage and indentation to the workpiece. Since the design of the elastic clamping member reduces damage to the workpiece, it also reduces downtime and maintenance costs caused by workpiece damage, and at the same time reduces the impact on the workpiece processing quality during drilling or milling.

[0038] 2. The sliding frame can slide on the drilling frame and is driven by the driving member. This design enables the clamping and positioning mechanism to flexibly adapt to workpieces of different sizes and the position changes of the workpieces during transportation. For example, when the workpiece is thin, it is easy to jump during the drilling process. The clamping force can be appropriately adjusted through the driving member to make the workpiece slide stably;

[0039] 3. During the movement of the workpiece, the driving block is driven to slide by the transmission member, the driving block drives the slider to approach the workpiece, and the slider drives the elastic clamp to squeeze the workpiece. Through the arrangement of the above structure, the squeezing force applied to the workpiece can be maintained, so that the workpiece remains stable during the drilling process, and the processing quality of the workpiece can be maintained.
