Description

Technical Field

[0001] The utility model relates to the technical field of press-fitting machines, in particular to a catheter positioning and locking mechanism for a catheter press-fitting machine. Background Art

[0002] A press is a mechanical device that presses parts into a mold or workpiece through pressure. It is widely used in industries such as automobiles, aviation, electronics, and home appliances, and is one of the important equipment on the assembly line.

[0003] When press-fitting a catheter, a press machine is required to apply pressure so that the catheter and the workpiece fit tightly. Currently, when the press machine is press-fitting the catheter, the catheter needs to be positioned manually or with tools to facilitate the press machine's pressure application. However, in actual use, since the catheter will generate a downward feed amount during the press-fitting process, manual support or tool fixation methods are prone to deviations, resulting in damage to the workpiece connection. In addition, the manual fixation method of the catheter has poor accuracy and is difficult to fix in the center, which is prone to processing errors and affects product quality.

[0004] In view of this, the utility model proposes a catheter positioning and locking mechanism for a catheter press-fitting machine. Utility Model Content

[0005] The purpose of the present utility model is to provide a catheter positioning and locking mechanism for a catheter press-fitting machine, so as to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a catheter positioning and locking mechanism for a catheter press-fitting machine, comprising a mounting seat, a press-fitting assembly being mounted on the upper side of the mounting seat, a mounting shell being mounted on one side of an inner wall of the mounting seat, a bidirectional screw being rotatably engaged with one side of the inner wall of the mounting shell, a servo motor being fixedly connected to one end of the bidirectional screw being mounted on one side of the mounting shell, two drive blocks being threadedly engaged with the bidirectional screw, one side of the drive block being fixedly connected to a support frame, and opposite sides of the two support frames being fixedly connected to a fixed shell;

[0007] The inner walls of the two fixed shells are both slidably and elastically matched with slides, the opposite sides of the two slides are fixedly connected with arc-shaped clamping plates, and the upper side of the mounting seat is provided with a fixing mechanism.

[0008] Preferably, the two driving blocks are both slidably fitted on the inner wall of the mounting shell, and the inner wall of the arc-shaped clamping plate is provided with an anti-slip pad.

[0009] Preferably, the inner wall of the fixed shell is fixedly connected with a slide rod, the slide plate is slidably fitted on the slide rod, a return spring is sleeved on the slide rod, and both ends of the return spring are fixedly connected to the slide plate and the fixed shell respectively.

[0010] Preferably, the fixing mechanism includes a plurality of dovetail grooves provided on the lower side of the inner wall of the mounting seat, a supporting plate arranged on the inner wall of the mounting seat, and a plurality of dovetail blocks fixedly connected to the lower side of the supporting plate, wherein the dovetail blocks cooperate with the dovetail grooves.

[0011] Preferably, a mounting groove is provided on one side of the mounting seat, and a collection box is slidably fitted on the inner wall of the mounting groove.

[0012] Preferably, a plurality of supporting legs are installed on the lower side of the mounting seat, and a shock-absorbing pad is fixedly connected to the lower side of the supporting legs.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] A catheter positioning and locking mechanism for a catheter press-fitting machine is provided. By providing a fixed shell, when a servo motor drives a driving block to move, an arc-shaped clamping plate on one side of the fixed shell can clamp and lock the catheter. When a press-fitting assembly applies pressure to the end of the catheter, the arc-shaped clamping plate moves downward accordingly to limit the movement of the catheter, thereby increasing the accuracy of the catheter press-fitting. Under the action of a bidirectional screw rod, the arc-shaped clamping plate is used to center the catheter, reducing the operational difficulty of the press-fitting process.

[0015] At the same time, the sliding rod and the reset spring can drive the arc-shaped clamping plate to reset after it is separated from the catheter, so that it is convenient for next use. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] like Figure 1 - Figure 4 As shown, the utility model provides a technical solution: a catheter positioning and locking mechanism of a catheter press-fitting machine, comprising a mounting base 1, a press-fitting assembly 2 is mounted on the upper side of the mounting base 1, a mounting shell 3 is mounted on one side of the inner wall of the mounting base 1, a bidirectional screw rod 4 is rotatably engaged with one side of the inner wall of the mounting shell 3, a servo motor 18 fixedly connected to one end of the bidirectional screw rod 4 is mounted on one side of the mounting shell 3, two driving blocks 5 are threadedly engaged on the bidirectional screw rod 4, one side of the driving block 5 is fixedly connected to a support frame 6, and the opposite sides of the two support frames 6 are fixedly connected to a fixed shell 7;

[0024] The inner walls of the two fixed shells 7 are slidably and elastically matched with slide plates 8, and the opposite sides of the two slide plates 8 are fixedly connected with arc-shaped clamping plates 9. A fixing mechanism 10 is provided on the upper side of the mounting seat 1.

[0025] In this embodiment, the two drive blocks 5 are slidably fitted on the inner wall of the mounting shell 3, and the inner wall of the arc-shaped clamping plate 9 is provided with an anti-slip pad 11. Specifically, by providing the arc-shaped clamping plate 9 and the anti-slip pad 11, the conduit material is clamped and fixed, thereby increasing the clamping effect.

[0026] In this embodiment, a slide bar 12 is fixedly connected to the inner wall of the fixed housing 7, and the slide plate 8 is slidably engaged with the slide bar 12. A return spring 13 is sleeved on the slide bar 12, and the two ends of the return spring 13 are respectively fixedly connected to the slide plate 8 and the fixed housing 7. Specifically, the provision of the slide bar 12 increases the stability of the slide plate 8 when it is raised and lowered.

[0027] The fixing mechanism 10 of this embodiment includes a plurality of dovetail grooves 101 formed on the underside of the inner wall of the mounting base 1, a supporting plate 102 disposed on the inner wall of the mounting base 1, and a plurality of dovetail blocks 103 fixedly connected to the underside of the supporting plate 102. The dovetail blocks 103 cooperate with the dovetail grooves 101. Specifically, the fixing mechanism 10 is provided to facilitate replacement of the supporting plate 102 according to the specifications of the workpiece, thereby increasing the convenience of the device.

[0028] One side of the mounting base 1 of this embodiment is provided with a mounting groove 14, and the inner wall of the mounting groove 14 is slidably fitted with a collection box 15. Specifically, by providing the collection box 15, it is convenient to place materials or workpieces.
