The point-by-point positioning method has complicated steps. Especially when drilling cylindrical mechanical seals, in order to ensure the stability of the workpiece, it is often necessary to position the cylindrical mechanical seals at least at four points. The traditional method of positioning the four points one by one is likely to slow down the overall processing progress, and the one-by-one positioning method is difficult to ensure the alignment of the positioning points, and thus it is difficult to ensure the accurate positioning of the cylindrical mechanical seal after positioning.

[0005] In view of the existing problems in the prior art, when drilling cylindrical mechanical seals, in order to ensure the stability of the workpiece, it is often necessary to position the cylindrical mechanical seals at least at four points. The traditional method of positioning the four points one by one is likely to slow down the overall processing progress, and the one-by-one positioning method is difficult to ensure the alignment of the positioning points, and thus it is difficult to ensure the accurate positioning of the cylindrical mechanical seals after positioning. The utility model provides a benchtop drilling machine positioning device for mechanical seal processing, which can achieve four-point synchronous positioning of the outer wall of the cylindrical workpiece, saving the overall processing time of the mechanical seal, and the four-point positioning is performed synchronously, and the points after positioning correspond to each other, thereby ensuring that the cylindrical workpiece after positioning is accurately positioned and will not be skewed, thereby ensuring the stability of the subsequent benchtop drilling machine when drilling the cylindrical workpiece. The specific technical scheme is as follows:

[0006] A positioning device for a benchtop drilling machine for machining mechanical seals comprises a benchtop drilling machine, a base being arranged at the top of the benchtop drilling machine, side panels being symmetrically and vertically mounted on the left and right sides of the upper surface of the base, a connecting plate being mounted correspondingly at the front and rear side walls of each side panel, a rotating rod being rotatably connected to the outer wall of the connecting plate at the front and rear sides on the opposite side, a positioning claw being fixedly connected to the outer wall of the rotating rod, the positioning claw being arranged in a hook shape, and a positioning block being mounted at the free end of the top of the positioning claw.

[0007] In the above technical solution, the positioning claws on the left and right sides are arranged in an inwardly buckled manner, and the positioning claws on the left and right sides can be relatively opened and closed.

DETAILED DESCRIPTION

[0023] The following is a combination of specific implementation cases and attached Figure 1-Figure 4 The present invention is further described below, but the present invention is not limited to these embodiments.

[0024] When drilling cylindrical mechanical seals, the traditional method of positioning one by one is likely to slow down the overall processing progress, and the method of positioning one by one is difficult to ensure the alignment of the positioning points, and thus it is difficult to ensure the accurate positioning of the cylindrical mechanical seals after positioning. Figures 1 to 4 As shown, a bench-type drilling machine positioning device for machining mechanical seals is proposed, including a bench-type drilling machine 1. The bench-type drilling machine 1 is an existing equipment component, which can perform operations such as drilling processing on mechanical seals. Its model is not limited here. A base 2 is arranged on the top of the bench-type drilling machine 1. Side panels 3 are symmetrically and vertically installed on the left and right sides of the upper surface of the base 2. The side panels 3 provide support for the installation of other components. A connecting plate 4 is correspondingly installed on the front and rear side walls of each side panel 3. The outer walls of the connecting plates 4 on the front and rear sides are rotatably connected to a rotating rod 5 on the opposite side through a bearing, that is, two rotating rods 5 are arranged, and the two rotating rods 5 can rotate along the outer wall of the connecting plate 4. For the action, the outer wall of the rotating rod 5 is fixedly connected with a positioning claw 6, and the positioning claw 6 is set in a hook shape. A positioning block 7 is installed at the free end of the top of the positioning claw 6. When the bottom end of the positioning claw 6 is driven to rotate, the rotating rod 5 can be driven to rotate in a circumferential direction, thereby realizing the rotation of the positioning block 7 installed on the outer wall of the positioning claw 6 in the corresponding direction, thereby realizing the positioning of the outer wall of the mechanical seal by the positioning block 7; the positioning claws 6 on the left and right sides are set in an inward buckled manner, and the positioning claws 6 on the left and right sides can be relatively opened and closed. By setting the positioning claws set inwardly in pairs relative to each other, the positioning block 7 at the corresponding position can be driven to rotate and position on the outer wall of the mechanical seal.

[0025] See also Figures 2 to 4As shown, a screw 10 is rotatably connected to the front side of the inner cavity of the base 2 from left to right through a bearing, and external threads in opposite directions are symmetrically arranged on the left and right sides of the outer wall of the screw 10. A moving seat 11 is slidably sleeved on the left and right sides of the outer wall of the screw 10, and the moving seat 11 is provided with an internal thread that matches the external thread of the outer wall of the screw 10. A limiting rod 12 is installed from left to right on the rear side of the inner cavity of the base 2, and the limiting rod 12 and the screw 10 are arranged parallel to each other. The moving seat 11 is slidably sleeved on the outer wall of the limiting rod 12. When the screw 10 is driven to rotate, the moving seat 11 can be driven to move relative to or toward the outer wall of the screw 10 and the limiting rod 12; four moving blocks 13 are symmetrically arranged on the top of the outer wall of the moving seat 11, and every two moving blocks 13 are arranged correspondingly front and back. A through groove 14 is penetrated through the outer wall of the moving block 13 from front to back, and an inner groove 14 is opened at the bottom end of the outer wall of each positioning claw 6. The embedded groove body has a cross bar 15 installed on the inner wall of the embedded groove at the bottom end of the outer wall of the positioning claw 6, and the cross bar 15 is embedded in the inner cavity of the through groove 14. By driving the screw 10 to rotate on the right side, the two movable seats 11 threadedly connected on the left and right sides of the outer wall of the screw 10 are caused to move synchronously, thereby driving the movable block 13 at the top of the movable seat 11 to move outward along the outer wall of the base 2. At this time, the cross bar 15 embedded in the inner cavity of the through groove 14 moves outward under the action of the moving block 13, so that the positioning claw 6 rotates inward with the rotating rod 5 as the axis, so as to prompt the positioning block 7 to gradually fit and position at the outer wall of the cylindrical workpiece 16. Since the four movable blocks 13 on the left and right sides move synchronously, the four positioning claws 6 and the positioning block 7 rotate inward synchronously to realize the positioning of the cylindrical workpiece 16; the opened bench drilling machine 1 can process the positioned cylindrical workpiece 16.

[0026] Specific reference Figure 2 As shown, a supporting platform 8 is installed in the middle of the upper surface of the base 2, and a groove body 9 is opened from front to back on the top of the supporting platform 8, and a cylindrical workpiece 16 is placed in the inner cavity of the groove body 9. The outer wall of the positioning block 7 is rotatably fitted with the outer wall of the cylindrical workpiece 16, and the bottom outer wall of the cylindrical workpiece 16 can be limited by the groove body 9. The cross-sectional shape of the groove body 9 is set to be V-shaped. The V-shaped groove body 9 can realize the synchronous limitation of both sides of the side wall of the cylindrical workpiece 16, thereby ensuring the stability of the bottom outer wall of the cylindrical workpiece 16, and through the positioning effect of the supporting platform 8, the groove body 9 and the four-point positioning block 7, it can be ensured that the position of the positioned cylindrical workpiece 16 is stable and will not be deflected, thereby ensuring the accuracy of the processing point when the bench drilling machine 1 processes the cylindrical workpiece 16 subsequently.

[0027] The working principle of a bench-type drilling machine positioning device for machining mechanical seals in this embodiment is as follows:

[0028] The cylindrical workpiece 16 is placed from front to back in the inner cavity of the groove body 9 opened at the top of the supporting platform 8, and the right side of the screw 10 is driven to rotate, so that the two movable seats 11 threadedly connected on the left and right sides of the outer wall of the screw 10 are synchronously moved, thereby driving the movable block 13 at the top of the movable seat 11 to move outward along the outer wall of the base 2. At this time, the cross bar 15 embedded in the inner cavity of the through groove 14 moves outward under the action of the moving block 13, so that the positioning claw 6 rotates inward with the rotating rod 5 as the axis, so that the positioning block 7 gradually fits and is positioned at the outer wall of the cylindrical workpiece 16. Since the four movable blocks 13 on the left and right sides move synchronously, the four positioning claws 6 and the positioning block 7 are synchronously rotated inward to achieve the positioning of the cylindrical workpiece 16; the opened bench drilling machine 1 can process the positioned cylindrical workpiece 16;

[0029] Compared with the traditional point-by-point positioning method, the utility model can realize four-point synchronous positioning of the outer wall of the cylindrical workpiece 16, saving the overall processing time of the mechanical seal, and the four-point positioning is carried out simultaneously, and the points after positioning correspond to each other, thereby ensuring that the cylindrical workpiece 16 after positioning is accurately positioned and will not be skewed, thereby ensuring the stability of the subsequent bench drilling machine when drilling the cylindrical workpiece 16.

For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
