Description

Technical Field

[0001] This utility model relates to the technical field of water pump production equipment, specifically a clamping device for water pump production that prevents pinching injuries. Background Technology

[0002] During the processing of water pump housings, especially when drilling and grooving are performed using a drilling machine, the water pump housing needs to be reliably positioned and clamped. However, most existing clamping devices are single-point control types, which pose a risk of premature clamping or sudden operation due to misoperation, easily leading to pinching accidents. In particular, when operators place or adjust the water pump housing, careless operation can easily cause personal safety issues. In addition, some devices lack multi-directional limiting structures for the water pump housing, resulting in unstable processing accuracy.

[0003] Based on this, the present invention designs a clamping device for water pump production that prevents pinching injuries, in order to solve the above problems. Summary of the Invention

[0026] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a clamping device for water pump production that prevents pinching injuries, including: a drilling machine base 16 and a water pump housing 17; the top of the drilling machine base 16 has an opening and two symmetrical linear slide rails 1 are fixedly connected to the opening, a clamping seat 2 is slidably connected between the two linear slide rails 1, a servo electric cylinder 3 is fixedly connected to the bottom of the clamping seat 2, and two linkage controllers 12 are fixedly installed on the top of the drilling machine base 16, and the servo electric cylinder 3 is simultaneously controlled to extend and retract through the two linkage controllers 12;

[0028] One end of the telescopic shaft of the servo electric cylinder 3 passes through the clamp 2 and is fixedly connected to the connecting sleeve 4. Both ends of the connecting sleeve 4 are provided with telescopically adjustable pressure plates 5. The top of the clamp 2 is symmetrically provided with positioning mechanisms.

[0029] The positioning mechanism includes a threaded seat 8 fixedly connected to the top of the clamp 2, a screw 9 threadedly connected to one end of the threaded seat 8, an auxiliary plate 10 rotatably connected to one end of the screw 9, and a throttle 11 fixedly connected to one end of the screw 9.

[0030] Two linkage controllers 12 are used to form a control logic that can only be triggered by pressing them simultaneously. The servo electric cylinder 3 is controlled to perform clamping and releasing actions. The servo electric cylinder 3 drives the connecting sleeve 4 and the adjustable pressure plates 5 on both sides to clamp the water pump housing 17. The process requires both hands to press simultaneously to avoid accidental operation and injury. Before the pressure plate 5 clamps, the positioning mechanism at the top of the clamping seat 2 provides multi-point left and right limit to assist in the placement of the water pump housing 17. The servo electric cylinder 3 moves precisely, and the pressure plate 5 is adjustable to accommodate more water pump housings 17.

[0031] In a further preferred embodiment, a lead screw sleeve 15 is fixedly connected to the bottom of the clamp 2, a servo motor 13 is fixedly installed on the inner wall of the punching machine table 16, and a lead screw 14 is fixedly connected to the output shaft of the servo motor 13. The lead screw 14 is threaded through the lead screw sleeve 15 and is rotatably connected to the inner wall of the punching machine table 16 at the other end.

[0032] A lead screw sleeve block 15 is set at the bottom of the clamp 2. The lead screw 14 is driven to rotate by the servo motor 13, so that the clamp 2 can be translated along the linear slide rail 1 to achieve position adjustment. The servo motor 13 is controlled by the punching machine 16, so there is no need to manually move the clamp 2, saving labor.

[0033] More preferably, the pump housing 17 has an impeller inlet in the middle and two connecting arms fixedly installed on the outer wall; both auxiliary plates 10 are L-shaped structures and respectively abut against the ends of the two connecting arms.

[0034] The pump housing 17 is equipped with an integrated connecting arm. The adjusted L-shaped auxiliary plate 10 can fit with the end of the connecting arm to form an auxiliary limit.

[0035] More preferably, the outer wall of the pressure plate 5 is provided with multiple adjustment through holes 6, and the outer wall of the connecting sleeve 4 is threaded with an adjustment bolt 7, with one end of the adjustment bolt 7 passing through the adjustment through hole 6 to adjust the extension and retraction position of the pressure plate 5.

[0036] Multiple adjustment holes 6 are provided on the pressure plate 5, and the position of the pressure plate 5 can be adjusted by inserting the adjustment bolts 7 on the connecting sleeve 4 into these holes to accommodate more workpieces. The manual adjustment method makes it easy for workers to adapt quickly.

[0037] More preferably, the two linkage controllers 12 are electrically connected to the servo cylinder 3, and are used to control the extension and retraction of the servo cylinder 3 when the two linkage controllers 12 are pressed at the same time.

[0038] Using normally open buttons, and through existing electrical linkage logic, both buttons must be pressed simultaneously to form a closed circuit, driving the servo cylinder 3 to move, thus forcing two-hand operation mechanism to prevent hand injury during single-handed operation.

[0039] A specific application of this embodiment is as follows: The water pump housing 17 is placed on the clamp 2 of the drilling machine 16, so that the impeller port of the water pump housing 17 passes through the telescopic shaft of the servo cylinder 3 and the connecting sleeve 4. The auxiliary plate 10, which is adjusted by rotating the handle 11 in advance, is positioned after abutting and fitting with the two connecting arms of the water pump housing 17. After positioning, according to the size of the water pump housing 17, the extension position of the pressure plate 5 is adjusted by adjusting the through hole 6 and the fastening bolt to ensure that the water pump housing 17 is pressed down. Then, the operator presses the two linkage controllers 12 at the same time. The linkage controllers 12 form a closed control circuit, which drives the servo cylinder 3 to move. Its telescopic shaft pushes the connecting sleeve 4 to move the pressure plates 5 on both sides downward, clamping and fixing the water pump housing 17. Then, the servo motor 13 in the drilling machine 16 drives the lead screw 14 to rotate, so that the clamp 2 moves along the linear slide rail 1 and is adjusted to the drilling position for processing. After processing, the linkage controller 12 is released, the servo cylinder 3 extends and retracts in the opposite direction, the pressure plate 5 is reset, and the water pump housing 17 is taken out.
