Description

Technical Field

[0001] This utility model relates to the technical field of drilling equipment in mechanical manufacturing, specifically a drilling equipment for mechanical manufacturing with positioning function. Background Technology

[0002] Mechanical manufacturing refers to the process of using machines, tools and equipment to process raw materials and manufacture various mechanical products. Mechanical manufacturing mainly includes design, processing, assembly and testing. During the processing, for the connection and installation of different parts, drilling equipment is mostly used to open holes for locking connection and assembly.

[0003] The utility model disclosed in CN112846276A is a positioning drilling machine. A sliding groove is provided on the outside of the machine housing, and the sliding base can drive the drilling head to move up and down. Before drilling, the drilling position can be marked on the outer surface of the workpiece by a positioning mechanism. Then, the positioning mechanism is moved away from the outer surface of the workpiece by a trigger mechanism, and the drilling is carried out along the marked position. The addition of two mechanisms on the outside of the machine makes it easier to determine the drilling position of the workpiece, avoids the problem of the drilling position being inaccurate due to manual marking by the operator, and greatly improves the accuracy of drilling.

[0004] However, the above-mentioned drilling machines with positioning effects still have the following problems in actual use: Although the positioning effect is achieved by the reciprocating lifting of the drilling machine, this positioning method cannot guarantee the accuracy of the workpiece during alignment. At the same time, the workpiece does not have an effective limiting device, and stability cannot be guaranteed during alignment and the lowering of the drilling machine. Furthermore, manual operation is still required when the drilling position needs to be adjusted later, which affects the drilling accuracy and does not improve the drilling efficiency.

[0005] Therefore, a drilling device for mechanical manufacturing with positioning function is proposed to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a drilling equipment for mechanical manufacturing with positioning function, in order to solve the problem that the existing drilling machine achieves the positioning effect during drilling by reciprocating lifting. However, this positioning method cannot guarantee the accuracy of the workpiece during alignment. At the same time, the workpiece does not have an effective limiting device, and the stability cannot be guaranteed during alignment and the descent of the drilling machine. Furthermore, when it is necessary to adjust the drilling position later, manual operation is still required, which affects the drilling accuracy and cannot improve the drilling efficiency.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a drilling device for mechanical manufacturing with positioning function, comprising a support base, and a lifting slide rod fixedly installed behind the top surface of the support base, wherein a drilling platform is slidably arranged above the lifting slide rod; further comprising:

[0008] The top surface of the support base is provided with a positioning mechanism, and the positioning mechanism includes a positioning platform, and positioning frames are symmetrically arranged on the left and right sides of the top surface of the positioning platform.

[0009] The drilling platform is equipped with a drilling mechanism on its top, and the drilling mechanism includes a drilling machine body. A guide gear is rotatably mounted on the left rear side of the drilling platform via a bearing.

[0010] Preferably, the positioning mechanism includes an eccentric rotating shaft, the bottom end of which is rotatably mounted inside the bottom surface of the support base via a bearing, and the top end of which is fixedly connected to the bottom surface of the positioning platform. The rotation of the eccentric rotating shaft drives the positioning platform to move eccentrically to adjust its position.

[0011] Preferably, the positioning mechanism includes a main bidirectional threaded rod, which is rotatably mounted on the front and rear sides of the positioning platform via bearings. The right end of the main bidirectional threaded rod is engaged with a pulley assembly, and the main bidirectional threaded rod is threaded through the bottom surface of the positioning platform on both the left and right sides.

[0012] Preferably, the positioning mechanism includes a secondary bidirectional threaded rod, which is rotatably mounted inside a symmetrically arranged positioning frame via a bearing. Positioning components are slidably mounted on both the front and rear sides of the symmetrically arranged positioning frame, and the symmetrically arranged positioning components are threadedly connected to the secondary bidirectional threaded rod.

[0013] Preferably, the positioning mechanism includes a main contact plate and a secondary contact plate, and the main contact plate and the secondary contact plate are elastically slidable on the left and right sides of the inner end of the positioning component, and the rear ends of the adjacent main contact plates and secondary contact plates are connected to each other by a traction steel cable.

[0014] Preferably, the positioning mechanism includes a drive shaft, which is rotatably mounted behind the top surface of the positioning platform via a bearing. The positioning platform is connected to the rear end of the internal double-threaded rod of the positioning frame via a bevel gear set. The meshing bevel gear sets are connected by a retaining bracket. The drive shaft and the bevel gear set on the outer wall slide and follow rotation through a concave-convex structure.

[0015] Preferably, the drilling mechanism includes a guide rack, which is fixedly installed on the left side of the top surface of the support base. The guide rack meshes with the guide gear inside the drilling platform. A guide wheel is fixedly provided at the right end of the guide gear. The rotation of the guide wheel and the guide gear drives the drilling platform and the drilling mechanism to descend to realize the drilling operation.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows: This drilling equipment for mechanical manufacturing with positioning function uses a movable positioning component above the positioning platform to position and lock the mechanical workpiece, and the eccentric rotating shaft drives it to adjust for drilling position, so as to perform efficient drilling through the descent of the drilling mechanism. The specific details are as follows:

[0017] 1. By rotating the main bidirectional threaded rods on the left and right sides of the positioning platform, which are engaged by pulley assemblies, the positioning frames connected by threads on the left and right sides are driven to slide inward, thereby changing the distance between the positioning frames and the workpiece.

[0018] The drive shaft is rotated by the bevel gear set, which drives the auxiliary double-threaded rod to rotate, causing it to move the positioning component closer to the mechanical workpiece. The main contact plate contacts and squeezes one side of the outer wall of the mechanical workpiece, and then moves backward to loosen the traction cable. After the elastically connected auxiliary contact plate is in a relaxed state, it slides inward to squeeze the other side wall of the workpiece, positioning the workpiece to prevent it from moving or misaligning during drilling.

[0019] 2. The rotation of the guide wheel drives the fixedly connected guide gear and guide rack to mesh with each other. Then, the guide rack limits the drilling platform and drives the drilling machine body to descend along the direction of the lifting slide, thereby realizing the drilling process for the positioned mechanical workpiece.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figures 1-7 The present invention provides the following technical solution:

[0030] Example 1: To solve the problems encountered by existing drilling machines used for machining mechanical workpieces, this example provides a drilling device for mechanical manufacturing with a positioning function. The device includes a support base 1, a positioning mechanism on the top surface of the support base 1, and a positioning platform 4. Positioning frames 5 are symmetrically arranged on the left and right sides of the top surface of the positioning platform 4. The positioning mechanism includes an eccentric rotating shaft 8, the bottom end of which is rotatably mounted inside the bottom surface of the support base 1 via a bearing, and the top end of which is fixedly connected to the bottom surface of the positioning platform 4. The rotation of the eccentric rotating shaft 8 drives the positioning platform 4 to move eccentrically to adjust its position. The positioning mechanism also includes a main bidirectional threaded rod 9, which is rotatably mounted on the front and rear sides of the positioning platform 4 via a bearing. The right end of the main bidirectional threaded rod 9 is meshed with a pulley assembly 10, and the threads of the main bidirectional threaded rod 9 penetrate the bottom surfaces of the left and right sides of the positioning platform 4.

[0031] The positioning mechanism includes a secondary bidirectional threaded rod 11, which is rotatably mounted inside a symmetrically arranged positioning frame 5 via bearings. Positioning components 12 are slidably mounted on both the front and rear sides of the symmetrically arranged positioning frame 5, and are threadedly connected to the secondary bidirectional threaded rod 11. The positioning mechanism also includes a main contact plate 13 and a secondary contact plate 14, which elastically slide on the left and right sides of the inner end of the positioning components 12, respectively, and are installed adjacent to each other. The rear ends of the main contact plate 13 and the auxiliary contact plate 14 are connected to each other by a traction steel cable 16; the positioning mechanism includes a drive shaft 17, and the drive shaft 17 is rotatably set behind the top surface of the positioning platform 4 through a bearing, and the positioning platform 4 is connected to the rear end of the auxiliary double-threaded rod 11 inside the positioning frame 5 through a bevel gear set 18, and the bevel gear sets 18 that mesh with each other are connected by a retaining bracket 19, while the drive shaft 17 and the bevel gear set 18 on the outer wall slide and follow rotation through a concave-convex structure.

[0032] like Figures 5-7 As shown, the machine to be drilled is placed at the top center of the positioning platform 4. Then, by rotating the main bidirectional threaded rod 9 on the left and right sides inside the positioning platform 4, which is engaged with the pulley assembly 10, the positioning frame 5 connected by threads on the left and right sides is driven to slide inward, thereby changing the distance between the positioning frame 5 and the workpiece.

[0033] The drive shaft 17, which is rotated on the top of the positioning platform 4, drives the meshing secondary bidirectional threaded rod 11 to rotate via the bevel gear group 18. This causes the secondary bidirectional threaded rod 11 to move the positioning assembly 12 closer to the mechanical workpiece. At the same time, the main contact plate 13 on the inner side of the positioning assembly 12 contacts and presses against one side of the outer wall of the mechanical workpiece. After moving backward, the traction cable 16 is released, so that the elastically connected secondary contact plate 14 slides inward after being in a relaxed state, and then contacts and presses against the other side of the outer wall of the workpiece, thereby positioning the workpiece and preventing it from moving or misaligning when subjected to drilling force.

[0034] like Figures 3-4 As shown, after locking and positioning the mechanical workpiece, when adjusting the position of the drill hole required for the mechanical workpiece, the eccentric rotating shaft 8 set inside the bearing base 1 is rotated to drive the positioning platform 4 fixedly connected to the top and the positioned workpiece to move in a circular motion, thereby adjusting the drilling position of the workpiece to avoid disassembly again and affecting processing efficiency.

[0035] Example 2: To solve the problems encountered by existing drilling machines used for machining mechanical workpieces, this example employs the following technical solution: A lifting slide bar 2 is fixedly installed behind the top surface of the support base 1, and a drilling platform 3 is slidably mounted above the lifting slide bar 2; a drilling mechanism is mounted on the top of the drilling platform 3, and the drilling mechanism includes a drilling machine body 6; a guide gear 7 is rotatably mounted on the left rear side of the drilling platform 3 via a bearing; the drilling mechanism includes a guide rack 20, which is fixedly installed on the left side of the top surface of the support base 1, and the guide rack 20 meshes with the guide gear 7 inside the drilling platform 3; a guide wheel 15 is fixedly mounted on the right end of the guide gear 7, and the rotation of the guide wheel 15 and the guide gear 7 causes the drilling platform 3 and the drilling mechanism to descend, thus achieving the drilling operation.

[0036] like Figures 1-2 As shown, the detachable clamp in front of the drilling platform 3 positions the drilling machine body 6 and adjusts the drill bit diameter according to the drilling specifications. Then, the rotation of the rotating guide wheel 15 drives the fixedly connected guide gear 7 to mesh with the guide rack 20. The guide rack 20 limits the drilling platform 3 to drive the drilling machine body 6 to descend along the direction of the lifting slide bar 2, thereby performing drilling processing on the positioned mechanical workpiece.

[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
