Description

Technical Field

[0001] The utility model relates to a pump cover pressing pin device. Background Art

Since two locating pins are typically required on a single pump cover, the existing press-fitting equipment for pump cover locating pins uses a fixed jig. This means that after inserting one locating pin, the operator must reposition the pump cover to insert the second locating pin or place it in another press-fitting machine. This method is inefficient and labor-intensive, increasing production costs. Utility Model Content

DETAILED DESCRIPTION

[0018] To make the above features and advantages of the present invention more clearly understood, embodiments are given below with reference to the accompanying drawings for detailed description, but the present invention is not limited thereto.

[0019] refer to Figures 1 to 5

[0020] A pump cover pinning device includes a machine platform 10, which is provided with a vibrating feeding mechanism. A pin removal mechanism is provided on the upper side of the output end of the vibrating feeding mechanism for clamping the pin rod and capable of horizontal movement and lifting. A pin delivery mechanism is provided on the lower side of the pin removal mechanism for clamping the pin rod and moving it longitudinally. A pump cover jig 50 capable of longitudinal movement is provided on the front side of the pin delivery mechanism. A lifting pressure head 60 is provided on the upper side of the pump cover jig for pressing the pin rod 1 into the pump cover positioning hole. The pin rod is loaded by the vibrating feeding mechanism, and the delivered pin rod is clamped by the pin removal mechanism and then sent to the pin delivery mechanism. The pin delivery mechanism sends the pin rod to the lower side of the lifting pressure head. The pump cover jig moves to move the pinning position of the workpiece to the lower side of the lifting pressure head, and the pin rod is pressed into the pinning position by the lifting pressure head.

[0021] In this embodiment, in order to better complete the loading of the pin rod, the vibration loading mechanism includes a vibration disk 21, and a stop block 22 is provided at the end of the output channel of the vibration disk, so that the pin rod can be blocked at the end of the output channel by the stop block, making it convenient for the pin removal mechanism to remove the pin.

[0022] In this embodiment, in order to remove the pin and move the pin rod, the pin removal mechanism includes a horizontally arranged first slide mechanism 31, and a first clamp 33 driven to rise and fall by a cylinder 32 is vertically installed on the slide of the first slide mechanism, so that the first clamp is driven downward by the cylinder to clamp the pin rod, and then the first clamp is driven by the first slide mechanism to move the pin rod horizontally to the pin delivery mechanism.

[0023] In this embodiment, in order to drive the pin to move longitudinally, the pin feeding mechanism includes a second slide mechanism 41 fixed longitudinally on the machine platform through a mounting seat 43, and a second clamp 42 is installed on the slide of the second slide mechanism, so that the pin rod sent into by the first clamp is clamped by the second clamp and moved longitudinally.

[0024] In this embodiment, to drive the longitudinal movement of the pump cover jig to change the position of the press pin, a slide 11 is longitudinally slidably connected to the machine platform via a linear guide 14. A screw 13 driven by a servo motor 12 is longitudinally mounted on the machine platform. A nut seat fixedly connected to the slide is threaded onto the screw, and the pump cover jig is mounted on the upper surface of the slide. The servo motor drives the screw to drive the slide longitudinally to adjust the position of the pump cover jig.

[0025] In this embodiment, to better position the pump cover, the pump cover fixture includes a base plate 51, with a workpiece support pin 52 fixed to one side. Workpiece positioning pins A 53 and B 54 are fixed to the other side. The two positioning holes on the pump cover that mate with workpiece positioning pins A and B serve as the first and second pressure pin positions where pins will be installed. Only a small portion of each pin, A and B, extends into the positioning holes in the pump cover, sufficient to position the pump cover and allow the pins to be inserted into the corresponding positioning holes during the subsequent pressure action.

[0026] In this embodiment, in order to drive the lifting pressure head to move up and down, a seat plate 62 is installed on the machine platform through the guide column 61. The lower side of the seat plate is provided with a pressure plate 64 which is slidably connected with the guide column and driven to move up and down by the electric cylinder 63. The lower side of the pressure plate is installed with a lifting pressure head and a three-claw clamp 65 for clamping the pin rod, so that the pin rod is clamped by the three-claw clamp and pressed into the positioning hole in cooperation with the lifting pressure head.

[0027] When the device is working, the manual pump cover workpiece is placed in the pump cover jig, the equipment is started, the pin removing mechanism cooperates with the pin sending mechanism to send a pin rod to the three-claw clamp on the lower side of the lifting pressure head and clamp it; the pump cover jig moves to move the pump cover to the first pin pressing position, the lifting pressure head lowers the pin, and rises after pressing; the pin removing mechanism cooperates with the pin sending mechanism to send another pin rod to the three-claw clamp and clamp it; the pump cover jig drives the pump cover to move to the second pin pressing position, the lifting pressure head lowers the pin, and rises after pressing; the pump cover jig moves to the material taking position, and the pump cover after pinning is manually taken out.

[0028] If the words "first" and "second" are used in the above-mentioned text of the utility model to limit components, those skilled in the art should know that the use of "first" and "second" is only for the convenience of description to distinguish the components. Unless otherwise stated, the above words have no special meaning.

Of course, the mutual fixed connection can also be replaced by an integrated structure (for example, manufactured by integral molding using a casting process) (except where it is obviously not possible to use an integrated molding process).

[0030] In addition, unless otherwise stated, the terms used in any technical solution disclosed in the above-mentioned utility model to express positional relationships or shapes include states or shapes that are approximate, similar or close thereto.
