Description

Technical Field

[0001] This utility model relates to the field of excavator tooth seat processing technology, specifically to an excavator tooth seat processing positioning device. Background Technology

[0002] The excavator tooth holder is an important component of an excavator, and it needs to be positioned during machining to facilitate subsequent processing.

[0003] Currently, when machining excavator tooth holders, the excavator tooth holder needs to be placed on a workbench and clamped securely before machining. However, this process does not involve positioning the tooth holder during machining, which may affect the accuracy of subsequent machining and thus reduce the quality of the finished product. Utility Model Content

[0004] In order to solve the above problems, the purpose of this utility model is to provide an excavator tooth seat machining and positioning device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model proposes an excavator tooth seat processing and positioning device, including a base, with two sliding grooves opened on the top of the base, and sliders slidably connected to the inner walls of the two sliding grooves, and a worktable fixedly installed on the top of the two sliders.

[0006] A positioning mechanism is provided on one side of the base, and the positioning mechanism includes a locking rod, a locking plate, a fixing rod, a fixing plate, and an electric cylinder. An electric cylinder is fixedly installed on one side of the inner wall of the workbench. A fixing plate is fixedly installed on the output shaft of the electric cylinder. One side of the fixing plate extends through and to the fixing rod outside the workbench. A locking plate is fixedly installed at one end of the fixing rod. Multiple locking rods are fixedly installed on one side of the base, and the locking rods are adapted to the locking plate.

[0007] In one example, the top of the workbench has a through groove, and the inner wall of the through groove is slidably connected to two mounting plates.

[0008] In one example, a V-shaped plate is fixedly mounted on one side of one of the mounting plates, and a connecting rod is fixedly mounted on one side of the other mounting plate, with a compression plate fixedly mounted at one end of the connecting rod.

[0009] In one example, a reciprocating motor is fixedly installed on one side of the worktable, and a bidirectional lead screw is fixedly installed on the output shaft of the reciprocating motor, and the bidirectional lead screw passes through and extends into the worktable.

[0010] In one example, the outer rings of the bidirectional lead screw located within the worktable are threadedly connected to two mounting plates.

[0011] In one example, a servo motor is fixedly mounted on one side of the worktable, and a lead screw is fixedly mounted on the output shaft of the servo motor, passing through and extending into the slide groove, and the lead screw is threadedly connected to the slider.

[0012] The excavator tooth holder machining and positioning device proposed in this utility model can bring the following beneficial effects:

[0013] 1. The excavator tooth holder processing and positioning device uses an electric cylinder to perform a return action to move a fixed plate, which in turn moves a fixed rod, thereby moving a clamping plate. When the clamping plate moves to match the clamping rod, it can engage the adjusted worktable and position the excavator tooth holder clamped on the worktable, thus facilitating subsequent processing.

[0014] 2. This excavator tooth holder processing and positioning device, by starting a reciprocating motor to drive the bidirectional lead screw to rotate, and driving the mounting plate to move in opposite directions, will drive the V-shaped plate and connecting rod to move in opposite directions, and drive the extrusion plate to move, thereby firmly clamping the excavator tooth holder, thus facilitating subsequent processing.

[0022] To more clearly illustrate the overall concept of this utility model, a detailed description will be provided below with reference to the accompanying drawings.

[0023] like Figures 1-5 As shown, an embodiment of this utility model proposes an excavator tooth seat processing and positioning device, including a base 1, with two sliding grooves 15 opened on the top of the base 1, and sliders 16 slidably connected to the inner walls of the two sliding grooves 15, and a worktable 2 fixedly installed on the top of the two sliders 16.

[0024] A positioning mechanism is provided on one side of the base 1, and the positioning mechanism includes a locking rod 13, a locking plate 12, a fixing rod 11, a fixing plate 10 and an electric cylinder 9. An electric cylinder 9 is fixedly installed on one side of the inner wall of the worktable 2. The output shaft of the electric cylinder 9 is fixedly installed on the fixing plate 10. One side of the fixing plate 10 extends through and to the fixing rod 11 outside the worktable 2. A locking plate 12 is fixedly installed at one end of the fixing rod 11. Multiple locking rods 13 are fixedly installed on one side of the base 1. The locking rods 13 are adapted to the locking plate 12.

[0025] Specifically, a through groove 14 is provided on the top of the workbench 2. Two mounting plates 5 are slidably connected to the inner wall of the through groove 14. The mounting plates 5 are slidably connected through the through groove 14. The mounting plates 5 fix the V-shaped plate 6 and the connecting rod 8 respectively, and drive the two to move towards each other.

[0026] Specifically, a V-shaped plate 6 is fixedly installed on one side of one of the mounting plates 5, and a connecting rod 8 is fixedly installed on one side of the other mounting plate 5. A pressing plate 7 is fixedly installed at one end of the connecting rod 8. The pressing plate 7 is fixed by the connecting rod 8 and moves to clamp it during the processing of the excavator tooth seat.

[0027] Specifically, a reciprocating motor 3 is fixedly installed on one side of the workbench 2, and a bidirectional lead screw 4 is fixedly installed on the output shaft of the reciprocating motor 3. The bidirectional lead screw 4 passes through and extends into the workbench 2. The reciprocating motor 3 drives the bidirectional lead screw 4 to rotate, and drives the mounting plate 5 to move towards each other in the through slot 14.

[0028] Specifically, the outer ring of the bidirectional lead screw 4 located inside the worktable 2 is threadedly connected to the two mounting plates 5, and the mounting plates 5 are moved by the bidirectional lead screw 4.

[0029] Specifically, a servo motor 18 is fixedly installed on one side of the worktable 2. The output shaft of the servo motor 18 is fixedly installed with a lead screw 17 that passes through and extends into the slide groove 15. The lead screw 17 is threadedly connected to the slider 16. The servo motor 18 drives the lead screw 17 to rotate, which in turn drives the slider 16 to move within the slide groove 15, and thus drives the worktable 2 to move.

[0030] Working principle: The excavator tooth holder is placed on the worktable 2. At this time, the reciprocating motor 3 is started to drive the double-acting screw 4 to rotate, which in turn drives the mounting plate 5 to move towards each other. This causes the V-shaped plate 6 and the connecting rod 8 to move towards each other, and also drives the pressing plate 7 to move, thus firmly clamping the excavator tooth holder for subsequent processing. At the same time, the electric cylinder 9 is started to drive the fixing plate 10 to move, which in turn drives the fixing rod 11 to move, causing the clamping plate 12 to move. When the clamping plate 12 separates from the clamping rod 13, the servo motor 18 is started to drive the screw 17 to rotate, which in turn drives one of the sliders 16 to move within the slide groove 15. This moves the worktable 2 and moves the excavator tooth holder clamped on the worktable 2 to the appropriate position. Then, the electric cylinder 9 performs a return action, causing the clamping plate 12 to return to its original position. When the clamping plate 12 and the clamping rod 13 are properly matched, the adjusted worktable 2 is then fixed and stabilized, thus positioning the tooth holder for subsequent processing.
