Description

Technical Field

[0001] The utility model relates to the technical field of positioning and clamping, and more specifically, to a positioning and clamping mechanism for accessory drilling equipment. Background Art

[0002] In traditional technical practice, the positioning and clamping mechanism is an important part of the accessory drilling equipment. Its main function is to ensure that the accessories being drilled maintain the correct position and fixed posture during the processing. However, such positioning and clamping mechanisms usually face some inconveniences in actual use, especially the connection method with external equipment has some limitations.

[0003] As we all know, most of the existing accessory drilling equipment uses the traditional method of bolt connection when connecting with external equipment. Although bolt connection provides a certain degree of connection stability, it usually requires additional tools and time to tighten or loosen the bolts during actual installation, which makes the entire installation process more cumbersome and inconvenient, thus affecting the user's convenience. In a fast-paced production environment, any loss of efficiency may lead to reduced production efficiency and increased costs.

[0004] In addition, existing equipment often lacks the function of automatic self-centering after installing and clamping the workpiece. This means that after the positioning clamping mechanism locks the accessory, if the position or posture of the accessory deviates, the operator needs to manually adjust it to achieve correct positioning. This not only increases the complexity of the operation, but may also cause precision deviations due to improper operation, affecting the final processing quality. This situation is particularly unfavorable in the field of precision manufacturing, because processing accuracy is directly related to product quality and performance. Summary of the invention

[0005] In view of the problems existing in the prior art, the utility model provides a positioning clamping mechanism for an accessory drilling device to solve the technical problems mentioned in the background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a positioning and clamping mechanism for an accessory drilling equipment, comprising a fixing cylinder, which is attached to the drilling equipment, and a fixing mechanism is arranged on the fixing cylinder, and the fixing mechanism comprises a lateral disk, a bottom block, an insertion rod, a pressure sleeve, a one-way sheet, a positioning mechanism, a return spring and a return mechanism, the lateral disk is installed on the side of the fixing sleeve, the bottom block is installed on the external equipment, the insertion rod is installed on the bottom block, the lateral disk is slidably connected to the insertion rod, the pressure sleeve is slidably connected to the insertion rod, a spiral groove is provided on the insertion rod, a plurality of one-way sheets are provided, and the plurality of one-way sheets are respectively installed on the side walls of the pressure sleeve according to the direction of the spiral groove, and the one-way sheets are clamped on the spiral groove, the positioning mechanism is installed on the insertion rod and the pressure sleeve, and the return spring is connected to the inner wall of the fixing cylinder and the return mechanism.

[0007] The utility model is further configured that a pressure plate is coaxially arranged on the pressure sleeve, and the pressure plate is fitted on the lateral plate. The design of the pressure plate ensures the increase of the fitting surface.

[0008] The utility model is further configured that the positioning mechanism includes a positioning rod, the positioning rod is coaxially installed on the insertion rod, a positioning groove is opened on the pressing sleeve, the positioning rod is inserted into the positioning groove, and the design of the positioning mechanism ensures the stability of the insertion rod.

[0009] The utility model is further configured that a push spring is sleeved on the positioning rod, and two ends of the push spring are respectively abutted against the insertion rod and the pressing sleeve, and the design of the push spring reduces the situation of virtual position.

[0010] The utility model is further configured that the return mechanism includes a resistance block, a plurality of slots are provided on the resistance block, and the plurality of slots are in resistance to the workpiece. The design of the return mechanism ensures the return of the workpiece.

[0011] The utility model is further configured that a plurality of return springs are provided, and the plurality of return springs are equidistantly installed on the inner wall of the fixed cylinder, and each of the return springs is provided with an annular sleeve. The design of the plurality of return springs ensures the continuity of the return.

[0012] The utility model is further configured such that a connecting block is installed on each of the annular sleeves, and the multiple connecting blocks are all located on the same circumference. The design of the connecting blocks ensures the supporting effect of returning to the center.

[0013] The utility model is further configured that a limiting ring is provided on the abutment block, a rotation groove is provided on the connection block, the limiting ring is rotatably connected in the rotation groove, and the design of the limiting ring ensures the rotation effect.

[0014] Compared with the prior art, the utility model provides a positioning clamping mechanism for an accessory drilling device, which has the following beneficial effects:

[0015] 1. The fixing mechanism realizes efficient and convenient connection through the cooperation of the lateral disc, bottom block, insertion rod, pressure sleeve, one-way piece and spiral groove. The lateral disc is installed on the side of the fixing sleeve, the bottom block is installed on the external equipment, and the insertion rod is installed on the bottom block. When fixing, the pressure sleeve slides along the insertion rod and sleeves it. The design of the one-way piece makes it unnecessary to follow the path of the spiral groove when inserting, which greatly simplifies the installation process. This structure not only promotes the simplicity of operation, but also ensures the firmness of the joint.

[0016] 2. The positioning mechanism consists of a positioning rod, a positioning groove and a push spring, which provides precise position calibration capabilities. The positioning rod is coaxially installed on the insertion rod and extends into the positioning groove. The setting of the push spring enables reverse thrust to be generated when force is applied, which helps to ensure that there is no looseness between the one-way plate and the spiral groove, thereby maintaining the stable positioning of the fixing mechanism, which is crucial to ensuring drilling accuracy and processing quality.

[0017] 3. The return mechanism includes a contact block, a slot, a return spring, an annular sleeve, a limit ring and a rotating groove. The slot on the contact block provides multi-point support when fixing the workpiece, reduces the single-point pressure on the workpiece surface and avoids damage. The return spring is installed on the inner wall of the fixed cylinder, connected to the bottom block through the annular sleeve, and returns the contact block to the appropriate position, which is conducive to ensuring the correct placement and efficient fixation of the workpiece. The combination of the limit ring and the rotating groove allows the contact block to rotate when fixing the workpiece, thereby providing additional flexibility and accuracy.

A push spring 12 is sleeved on the positioning rod 10, and the two ends of the push spring 12 respectively abut against the insertion rod 4 and the pressing sleeve 5.

[0028] In this embodiment, when fixing, since the bottom block 3 is installed on the external equipment, the position of the insertion rod 4 is fixed. When the fixing tube 1 needs to be connected, the lateral disk 2 is slidably connected to the multiple insertion rods 4, and then the pressing sleeve 5 is sleeved on the insertion rod 4. When inserting, due to the unidirectional setting of the one-way sheet 6, it is not necessary to insert along the spiral groove 8, and it can be clamped. At the same time, the positioning rod 10 is also inserted into the positioning groove 11, so that the insertion rod 4 and the pressing sleeve 5 can be positioned synchronously, and through the action of the push spring 12, they are respectively pressed on the pressing sleeve 5 and the insertion rod 4, so that a reverse thrust is applied, thereby avoiding the one-way sheet 6 and the spiral groove 8 from generating a virtual position, thereby completing the fixing process.

[0029] See also Figure 1 , Figure 2 and Figure 3 , as an embodiment of a positioning and clamping mechanism for an accessory drilling equipment of a return mechanism: the return mechanism includes a resistance block 13, a plurality of card slots 14 are opened on the resistance block 13, and the plurality of card slots 14 are in contact with the workpiece, a plurality of return springs 7 are provided, and the plurality of return springs 7 are respectively and equidistantly installed on the inner wall of the fixed cylinder 1, each return spring 7 is provided with an annular sleeve 15, each annular sleeve 15 is installed with a connecting block 18, and the plurality of connecting blocks 18 are all on the same circumference, a limiting ring 16 is provided on the resistance block 13, a rotating groove 17 is opened on the connecting block 18, and the limiting ring 16 is rotatably connected in the rotating groove 17.

[0030] More specifically, when it is necessary to clamp the workpiece, the workpiece is first clamped on multiple contact blocks 13. Since limit rings 16 are installed on multiple contact blocks 13, and the limit rings 16 are rotatably connected in the rotating groove 17, the contact blocks 13 can rotate along the rotating groove 17, so that the contact blocks 13 can effectively press against the workpiece.

[0031] In summary, when the overall device is in use or running: when fixing, since the bottom block 3 is installed on the external device, the position of the insertion rod 4 is fixed. When the fixing cylinder 1 needs to be connected, the side disk 2 is slidably connected to the multiple insertion rods 4, and then the pressing sleeve 5 is sleeved on the insertion rod 4. When inserting, due to the unidirectional setting of the one-way sheet 6, it is not necessary to insert along the spiral groove 8, and it can be clamped. At the same time, the positioning rod 10 is also inserted into the positioning groove 11, so that the insertion rod 4 and the pressing sleeve 5 can be positioned synchronously, and through the action of the push spring 12, they are respectively pressed on the pressing sleeve 5 and the insertion rod 4, thereby applying a reverse thrust, thereby avoiding the one-way sheet 6 and the spiral groove 8 from generating a virtual position, thereby completing the fixing process.

[0032] When it is necessary to clamp the workpiece, first clamp the workpiece on multiple contact blocks 13. Since limit rings 16 are installed on multiple contact blocks 13, and the limit rings 16 are rotatably connected in the rotation groove 17, the contact blocks 13 can rotate along the rotation groove 17, so that the contact blocks 13 can effectively press against the workpiece. The damage to the surface caused by excessive pressure at a single point is reduced by fixing multiple surfaces, and then it can be returned to the original position by the return spring 7, thereby ensuring the positioning effect.
