Description

Technical Field

[0001] This invention relates to the field of bearing processing equipment technology, and in particular to an oil hole drilling device for bearing processing. Background Technology

[0002] In the bearing manufacturing process, drilling oil holes is a crucial step in ensuring bearing lubrication performance. Traditional processes require drilling through-holes at specific locations on the bearing housing to allow for the injection of lubricating oil later. This effectively reduces the friction coefficient during bearing operation, improves heat dissipation efficiency, and extends bearing life. Current technologies often employ CNC drilling machines or specialized fixtures for this process, but these methods generally suffer from insufficient positioning accuracy and low loading / unloading efficiency, making them unsuitable for the high-speed, continuous processing demands of modern bearing production lines.

[0003] Patent publication number CN217941930U discloses an oil hole drilling device for bearing processing, which includes a slide rail. The left and right sides of the slide rail are symmetrically provided with passage grooves. The side walls of the slide rail are provided with a lower groove and an upper groove. A servo motor and an electric telescopic rod are provided on the bottom surface of the lower groove. The upper end of the servo motor shaft extends into the interior of the upper groove and is provided with a drive gear. By setting up the slide rail, after the bearing to be drilled is put into the slide rail, when the bearing abuts against the back of the baffle, the motor shaft of the servo motor drives the drive gear to rotate. Through the meshing transmission of the drive gear and two driven racks, the two clamping blocks are driven to move towards the bearing to center and position the bearing. Then, the bearing is drilled by the drill rod. After the drilling is completed, the electric telescopic rod drives the baffle to move down, so that the bearing rolls out of the slide rail, realizing rapid loading and unloading during the bearing oil hole drilling process. However, in actual processing, the bearing is first fixed to the clamping block by a motor before drilling. Using an additional motor to fix the bearing not only adds a drilling step but also increases production costs. The drilling process is cumbersome and detrimental to the bearing's usability. Furthermore, the entire system has stringent timing requirements, demanding precise coordination of clamping, drilling, and unloading actions. Any timing deviation in any step can lead to jamming or processing errors, significantly complicating equipment debugging.

[0004] In response to the aforementioned problems with existing technologies, the industry urgently needs to develop a simplified structure, reliable operation, and effective cost reduction device and method for drilling oil holes in bearings. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art, such as cumbersome drilling process, difficult equipment debugging, and high production cost, and to provide an oil hole drilling device for bearing processing, which saves drilling steps, improves drilling efficiency, reduces production costs, and facilitates the use of bearing drilling.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A bearing machining oil hole drilling device is used for drilling holes in bearings. The drilling device includes:

[0008] Support base;

[0009] The bearing storage cylinder, which is set on the support base and used to vertically stack the bearings in sequence, has a first through groove and a second through groove at the bottom of both sides.

[0010] And a drilling assembly disposed on the first through slot side for drilling the bearing, comprising an arc-shaped limiting block that can move horizontally and pass through the first through slot to limit the bearing, and a drill bit that can move horizontally and pass through the arc-shaped limiting block to drill the bearing.

[0011] Furthermore, the drilling assembly also includes:

[0012] Mounting plate installed on the support base;

[0013] A cylinder mounted on the mounting plate and movable horizontally;

[0014] The motor is mounted on the end of the cylinder, which includes an end face facing the bearing, a rotating shaft passing through the center of the end face, the rotating shaft being connected to the drill bit, and a connector being provided on the end face to connect with the arc-shaped limiting block.

[0015] Furthermore, the connector may include a telescopic rod, a spring, a combination of a telescopic rod and a spring, or other connection methods.

[0016] Furthermore, the arc-shaped limiting block includes:

[0017] Limiting block body;

[0018] An arc-shaped surface is provided on the body of the limiting block and matches the arc shape of the bearing;

[0019] A first through hole passes through the limiting block body and the arc-shaped surface, allowing the drill bit to pass through. This is used to clamp and limit the bearing, keeping it stable during drilling. The arc-shaped limiting block is made of a suitable material according to actual needs.

[0020] Furthermore, the arc-shaped surface fits the curved surface of the bearing, with a curvature tolerance of ±0.05mm.

[0021] Furthermore, a guide channel is provided at the second through groove to guide the machined bearing out.

[0022] Furthermore, the guide channel has a certain slope, with the end of the guide channel furthest from the bearing storage cylinder being the lowest and the end closest to the bearing storage cylinder being the highest.

[0023] Furthermore, the slope of the guide channel is 1° to 10°.

[0024] Furthermore, the drilling device also includes a baffle and stop rod assembly, which includes a movable baffle for opening or closing the second through slot and a stop rod that passes through the bearing storage cylinder and can pass through the second bearing from bottom to top.

[0025] Furthermore, the side wall of the bearing storage cylinder is provided with a second through hole for the stop bar to pass through.

[0026] Furthermore, the height of the second through hole is aligned with the inner side of the highest point of the second bearing from bottom to top inside the bearing storage cylinder, which is used to limit the bearing and prevent it from falling out.

[0027] Furthermore, the stop bar and the baffle move synchronously. When the stop bar moves toward the bearing storage cylinder, the baffle moves toward the direction of opening the second through slot.

[0028] Furthermore, the baffle rod assembly also includes:

[0029] A connecting mounting plate fixed to the support base;

[0030] An electric push rod is mounted on the connecting mounting plate, and the stop rod is connected to and driven by the electric push rod;

[0031] And a connecting plate that connects the electric push rod and the baffle.

[0032] Furthermore, the side wall of the bearing storage cylinder is connected to baffle grooves located on the upper and lower sides of the baffle, making the movement of the baffle more stable.

[0033] Furthermore, the bottom of the bearing storage cylinder is a guide plate with a chip removal groove, and a collection box for collecting waste chips generated during the bearing drilling process is provided at the bottom of the guide plate.

[0034] Furthermore, the guide plate has the same slope as the guide channel, with the highest position on the side closer to the second through groove and the lowest position on the side closer to the first through groove.

[0035] Furthermore, the top of the bearing storage cylinder is provided with a bearing storage compartment for storing bearings and allowing them to fall into the bearing storage cylinder.

[0036] Furthermore, the support base includes a base plate, a support end face located above the base plate, and a plurality of support columns connecting the base plate and the support end face.

[0037] Furthermore, the collection box is mounted on the base plate.

[0038] Furthermore, the support end face is provided with a slot for mounting the guide plate.

[0039] Compared with the prior art, the present invention has the following advantages:

[0040] (1) This invention uses an arc-shaped limiting block to limit and fix the bearing while simultaneously moving the drill bit, allowing the drill bit to pass through the arc-shaped limiting block. At this point, the drill bit is used to drill a hole in the bearing, eliminating the traditional step-by-step clamping-drilling process interval. The limiting and processing are completed in a single station, effectively shortening the cycle time, improving drilling efficiency, reducing production costs, and facilitating the use of drilled bearings. Furthermore, the mechanical linkage replaces the independent electrically controlled clamping device, reducing the number of electrical components, lowering energy consumption, and saving costs.

[0041] (2) The drilling device of the present invention is suitable for efficient processing of oil holes in bearing housings. Through the design of the arc-shaped limiting plate and the curved surface of the bearing outer diameter, high-precision positioning is achieved, which effectively ensures the quality of hole processing.

[0042] (3) This application, by setting up a baffle and stop rod assembly, enables the baffle and stop rod to move synchronously. When the stop rod moves toward the bearing storage cylinder, the baffle moves toward the direction of opening the second through slot. After the bearing is processed, the baffle releases its obstruction of the second through slot, allowing the drilled bearing to roll into the guide channel. At the same time, the stop rod enters the bearing storage cylinder to restrict the position of the un-drilled bearing, preventing it from falling.

[0043] (4) In this invention, the bearing storage cylinders in which the bearings are stacked vertically in sequence are used to achieve continuous material supply queue management, ensuring that only a single bearing at the bottom is in the processing position each time, thus avoiding drilling deviation caused by multiple workpieces overlapping.

[0112] In this embodiment, the height of the second through hole 35 is inside the highest point of the second bearing 1 from bottom to top inside the bearing storage cylinder 3, which is used to limit the bearing 1 and prevent it from falling.

[0113] In this embodiment, the stop bar 72 and the baffle 71 move synchronously. When the stop bar 72 moves toward the bearing storage cylinder 3, the baffle 71 moves toward the direction of opening the second through groove 32.

[0114] In this embodiment, the baffle rod assembly 7 further includes:

[0115] A connecting mounting plate 73 is fixed on the support base 2;

[0116] An electric push rod 74 is mounted on the connecting mounting plate 73, and the stop rod 72 is connected to and driven by the electric push rod 74;

[0120] In this embodiment, the guide plate 33 has the same slope as the guide channel 5, with the highest position on the side closer to the second through groove 32 and the lowest position on the side closer to the first through groove 31.

[0121] In this embodiment, the top of the bearing storage cylinder 3 is provided with a bearing storage compartment 34 for storing the bearing 1 and allowing it to fall into the bearing storage cylinder 3.

[0125] In this embodiment, the working principle and process of the oil hole drilling device are as follows:

[0126] The bearing 1 is placed in the bearing storage chamber 34, allowing it to fall into the bearing storage cylinder 3. They are stacked vertically, with the bottom bearing 1 contacting the guide plate 33. At this point, the electric push rod 74 pushes the baffle 71 to close the second through slot 31, simultaneously moving the stop rod 72 away from the bearing storage cylinder 3. The cylinder 44 is activated, driving the motor 45 towards the first through slot 31. Since the end face 451 of the motor 45 is connected to the arc-shaped limiting block 41 via the connector 46, the arc-shaped limiting block 41 moves, passing through the first through slot 31 and compressing and limiting the bearing 1. Simultaneously, the motor 45 is activated, causing the rotating shaft 452 to rotate, driving the drill bit 42 to rotate. This allows for simultaneous limiting by the arc-shaped limiting block 41 and machining by the drill bit 42 at a single station, effectively shortening the cycle time and improving drilling efficiency. Drilling debris falls into the collection box 6 via the chip discharge trough 331 and is collected. After the bearing 1 is processed, the motor 45 is turned off, and the cylinder 44 drives the arc-shaped limiting block 41 and the drill bit 42 to move away from the first through groove 31, thereby releasing the limiting effect on the bearing 1.

[0127] At this point, the electric push rod 74 is activated, causing the stop rod 72 to insert into the second through hole 35 of the bearing storage cylinder 3, thus restricting the position of the un-drilled bearing and preventing it from falling. Simultaneously, the connecting plate 75 drives the baffle 71 to release its obstruction of the second through slot 32, allowing the drilled bearing 1 to roll into the guide channel 5. After completion, the electric push rod 74 resets the stop rod 72 and baffle 71, and the processing of the next bearing 1 is repeated.

[0128] Although the present invention has been described in detail above with general descriptions, specific embodiments, and experiments, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
