Description

Technical Field

[0001] This utility model relates to the field of slot tooling, and in particular to a novel slot tooling. Background Technology

[0002] In the field of mechanical manufacturing, keyways, oil grooves, relief grooves, or irregularly shaped holes (such as square holes or D-shaped holes) are common structures in the internal bores of parts. These structures are used to transmit torque, lubricate, or position, and their machining accuracy directly affects the assembly quality and performance of the parts. Traditionally, machining these internal cavity structures requires specialized slotting machines, broaching machines, planers, or electrical discharge machining equipment.

[0003] However, while these devices are professional and efficient, they also have significant limitations: firstly, the procurement cost of specialized machine tools is expensive; secondly, for small-batch production or repair applications, it is not economical to configure specialized equipment for specific parts; and thirdly, due to space limitations, not all factories, especially small and medium-sized workshops, are equipped with these large specialized machines. Therefore, this application provides a novel slot tooling to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a new type of slot tooling. By converting circular motion into vertical linear reciprocating motion, it enables the processing of internal slots without the need for specialized slotting machines, broaching machines, and wire cutting machines. This facilitates operation during production and maintenance, and saves time for outsourcing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A novel slot fixture includes a housing, a sliding seat, and a cutting tool. An upper bearing seat and a lower bearing seat are respectively mounted at the midpoint of the upper and lower ends of the housing via multiple mounting bolts. A main shaft is rotatably mounted between the upper and lower bearing seats. A lever is fixedly sleeved on the outer wall of the main shaft inside the housing. Baffles are fixedly mounted on both sides of the front end of the housing. Pressure strips are mounted on the front ends of both baffles via multiple fastening bolts. The cutting tool passes through the sliding seat from top to bottom and is fastened inside the sliding seat by fixing bolts. Base plates are fixedly mounted at the upper and lower ends of the rear end of the sliding seat. A connecting shaft passes through both base plates, and a ball bearing seat is fixedly mounted at one opposite end of the connecting shaft. Ball bearings are rolled inside the two ball bearing seats at their opposite ends.

[0006] Furthermore, the opposite ends of the two connecting shafts both penetrate the base plate and are threadedly connected with locking nuts.

[0007] Furthermore, the dial plate adopts an inclined disc structure, with its outer edge located between two balls.

[0008] Furthermore, side protrusions are fixedly provided on both sides of the outer wall of the sliding seat, and a sliding groove is formed between the front end of the baffle and the rear end face of the pressure strip, with the side protrusions slidably disposed inside the sliding groove.

[0009] Furthermore, fixing plates are fixedly installed on both sides of the rear end face of the box.

[0010] This utility model has the following beneficial effects: This utility model proposes a novel slotting fixture, which consists of a housing, a spindle, a dial plate on the spindle, a sliding seat that can slide up and down, and a cutting tool fixed on the sliding seat. The spindle is driven by a drive source (servo motor) to rotate the dial plate, converting the circumferential rotation of the dial plate into the vertical linear motion required by the cutting tool, so that it moves up and down repeatedly. In this way, the internal slot can be processed without the need for a professional slotting machine, broaching machine, and wire cutting. It is convenient to operate in the production process and maintenance, and can save outsourcing time. Attached Figure Description

[0013] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Reference Figures 1-4This utility model provides an embodiment of a novel slot tooling, comprising a housing 2, a sliding seat 8, and a cutting rod 10. An upper bearing seat 4 and a lower bearing seat 11 are respectively mounted at the midpoint of the upper and lower end faces of the housing 2 via multiple mounting bolts. A main shaft 3 is rotatably mounted between the upper and lower bearing seats 4 and 11. A lever 12 is fixedly sleeved on the outer wall of the main shaft 3 inside the housing 2. Baffles 5 are fixedly mounted on both sides of the front end face of the housing 2. Pressure strips 6 are mounted on the front ends of both baffles 5 via multiple fastening bolts 7. The cutting rod 10 passes through the sliding seat 8 from top to bottom and is fastened inside the sliding seat 8 by fixing bolts 9. Base plates 14 are fixedly mounted at the upper and lower ends of the rear end face of the sliding seat 8. Connecting shafts are passed through both base plates 14, and ball bearing seats 15 are fixedly mounted at opposite ends of the connecting shafts. Ball bearings 16 are rolled inside the opposite ends of the two ball bearing seats 15.

[0015] Specifically, the bearing housings designed at the upper and lower ends can stably ensure the smooth and stable rotation of the spindle 3; the pressure bar 6 is bolted to the baffle 5 for easy disassembly, installation and maintenance; the tool inserter 10 is fastened by two fixing bolts 9, which not only enables quick disassembly and assembly but also provides better stability; and the ball bearing 16 is rolled inside the ball bearing seat 15, ensuring smooth rolling of the ball bearing 16. Working principle: The upper end of the spindle 3 is connected to the drive assembly. The drive assembly can be driven by a servo motor or other drive source to make the spindle 3 rotate. When the spindle 3 rotates, it drives the lower end of the dial plate 12 to rotate. Due to the specific tilt design of the dial plate 12, it will continuously form an up-and-down undulating effect at an edge point when rotating, thereby driving the ball 16 and the ball seat 15 to move up and down continuously, thus realizing the up-and-down movement of the entire sliding seat 8, causing the insert rod 10 on the sliding seat 8 to complete the up-and-down insertion movement.

[0016] In one embodiment of this utility model, the opposite ends of the two connecting shafts both pass through the base plate 14 and are threadedly connected to the locking nut 17; specifically, the lower end of the connecting shaft is fixed to the ball bearing seat 15, which can hang the entire ball bearing seat 15, while the upper end passes through the base plate 14 and is fastened by the locking nut 17, so that it can be stably installed on the base plate 14 and can be quickly adjusted according to the height requirements.

[0017] In one embodiment of this utility model, the dial plate 12 adopts an inclined disc structure, with the outer edge of the dial plate 12 located between two balls 16. Specifically, due to the inclined design of the dial plate 12, when the main shaft 3 rotates and the dial plate 12 rotates, a height difference will appear during the circumferential rotation. Since the outer edge of the dial plate 12 is between two balls 16, when a height difference is formed, it will squeeze and push the two balls 16 to move up and down, thereby completing the up and down movement of the ball seat 15 and the sliding seat 8, and finally moving the insert rod 10 up and down together.

[0018] In one embodiment of this utility model, side protrusions 13 are fixedly provided on both sides of the outer wall of the sliding seat 8, and a groove is formed between the front end of the baffle 5 and the rear end face of the pressure strip 6. The side protrusions 13 are slidably disposed inside the groove. Specifically, the groove structure formed by the combination of the baffle 5 and the pressure strip 6 restricts and guides the side protrusions 13, so that it can only slide up and down, thereby realizing the up and down cyclic movement of the entire insert rod 10.

[0019] In one embodiment of this utility model, fixing plates 1 are fixedly provided on both sides of the rear end face of the box body 2; specifically, the fixing plates 1 provided at the rear end are used to fix the entire tooling at the upper position of the required processing table. The fixing plates 1 are provided with multiple mounting holes, which can be quickly installed and fixed by bolts.

[0020] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
