Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, specifically to a parts sorting device, and more particularly to an automatic sorting device for ball-tooth products. Background Technology

[0002] Currently, drill bits are widely used in various industries such as geological exploration, mining, construction, oil and gas drilling, and trenchless engineering. With the development needs and the continuous expansion of the drill bit industry, the demand for high-quality, high-requirement carbide drill bit ball teeth products is also increasing.

[0003] Currently, the difficulty in precision grinding of ball teeth, especially the outer cylindrical grinding of high-end precision grinding ball teeth, lies in the fact that due to the inherent shape characteristics of the products, vibratory feeding is required. However, the random feeding direction when the product enters the grinding area makes it impossible to control the grinding dimensions, easily leading to dimensional abnormalities. This poor dimensional control has resulted in a bottleneck in increasing the production capacity of high-end precision grinding ball teeth, making it difficult to meet market demand. Furthermore, existing vibratory feeding methods are incompatible with ball teeth of different shapes. For some products with special shapes and varying sizes, manual intervention is still required during feeding and grinding, which is not only labor-intensive but also significantly impacts production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide an automatic splitting device that can automatically split ball tooth products and connect to a grinding machine to ensure that the feeding direction is consistent.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is as follows: An automatic sorting device includes a feeding mechanism that can arrange and transport multiple products in an orderly manner along an axial direction. The automatic sorting device also includes a sensing and identification mechanism for sensing and identifying the placement direction of the product ends. The output end of the feeding mechanism is connected to a sorting mechanism that separates and transports products with different end placement directions according to the sensing and identification results of the sensing and identification mechanism. The sorting mechanism includes a sorting roller for receiving products from the feeding mechanism and sorting and transporting the products. A first direction sorting and collection box and a second direction sorting and collection box are respectively provided on both sides of the sorting roller. The sensing and identification mechanism is located above the sorting roller. This automatic splitting device can automatically split high-end precision grinding drill bits, specifically ball teeth. The ball teeth are arranged axially in an orderly manner via a feeding mechanism and enter the splitting rollers one by one. After entering the rollers, a sensor identifies the end orientation of the product. Based on the sensor recognition result, the rollers group products with the same end orientation together and separate products with different orientations. For example, products with the head in front and the tail in back are sent to the first direction distribution collection box, while products with the tail in front and the head in back are sent to the second direction distribution collection box. This achieves continuous automatic splitting, ensuring consistent feeding direction during grinding and balanced automatic feeding. This effectively controls the outer diameter of centerless grinding products, such as ball teeth, significantly improving processing efficiency and quality while reducing the workload of manual operation, demonstrating high practical value.

[0006] Preferably, in the aforementioned automatic sorting device, the sorting roller is provided with a positioning slot for accommodating a single product. The sorting mechanism further includes a stepper motor for driving the sorting roller to rotate so that the positioning slot aligns with the output end of the feeding mechanism, the input end of the first-direction sorting and collecting box, and the input end of the second-direction sorting and collecting box. The sorting roller is connected to the stepper motor. After a single product enters the positioning slot, the stepper motor can drive the sorting roller to rotate according to the sensing and recognition status. By rotating in different directions, the product is fed into the first-direction sorting and collecting box or the second-direction sorting and collecting box, thereby achieving rapid automatic sorting.

[0007] Preferably, in the aforementioned automatic sorting device, the positioning slot includes a fixed positioning slot and a replaceable positioning slot. The fixed positioning slot is an arc-shaped groove on the dispensing roller. A mounting position for installing the replaceable positioning slot is provided next to the fixed positioning slot. A cooperating positioning element is provided between the fixed positioning slot and the replaceable positioning slot. The replaceable positioning slot is detachably mounted in the fixed positioning slot via the mounting position and the positioning element. The replaceable positioning slot allows for quick switching to accommodate products with different outer diameters. The mounting position and positioning element structure ensure precise positioning and fixation of the replaceable positioning slot. When switching between different product specifications, only the replaceable positioning slot needs to be replaced, significantly improving product switching efficiency.

[0008] Preferably, the automatic sorting device described above has four positioning slots on the sorting roller, which are evenly spaced on the outer edge of the roller. Each of the four positioning slots can operate independently. After the previous round of product sensing, identification, and sorting, one empty positioning slot will inevitably connect with the output end of the feeding mechanism, thus quickly starting the next round of automatic sorting without the need to reset the positioning slot, saving reset time and improving sorting efficiency.

[0009] Preferably, in the aforementioned automatic sorting device, the sensing and identification mechanism includes a laser sensor, which is fixed on a mounting frame and positioned directly opposite the dispensing roller. The laser sensor can accurately detect whether a product entering the machine has a spherical arc end or a chamfered tail end, based on the characteristics of spherical toothed products. Based on the detected model, it provides feedback and controls a stepper motor to rotate the dispensing roller in different directions to achieve dispensing.

[0010] Preferably, in the aforementioned automatic head-splitting device, the sensing and identification mechanism mounting frame includes a support plate, a vertical adjustment plate, a horizontal adjustment plate, and a fixed plate. One end of the support plate is fixedly mounted, and the other end is connected to one end of the horizontal adjustment plate. The other end of the horizontal adjustment plate is connected to one end of the vertical adjustment plate, and the other end of the vertical adjustment plate is connected to one end of the fixed plate. The other end of the fixed plate is connected to the laser sensor. The horizontal and vertical positions of the laser sensor can be adjusted by adjusting the mounting positions of the vertical and horizontal adjustment plates, thereby enabling compatibility with feature recognition sensing of products of different specifications.

[0011] Preferably, in the aforementioned automatic sorting device, the feeding mechanism includes a vibratory feeder, a feeding guide trough, and a guide positioning block. The input end of the feeding guide trough is connected to the output end of the vibratory feeder, the output end of the feeding guide trough is connected to the input end of the guide positioning block, and the output end of the guide positioning block is connected to the distributing roller. The cross-section of the feeding guide trough is V-shaped, and the guide positioning block has a positioning cavity for the product to pass through axially. The V-shaped feeding guide trough structure allows products of different outer diameters to be guided and transported within the feeding guide trough, thus arranging them orderly in the axial direction, providing good guidance for subsequent sorting operations. The guide positioning block ensures that products entering from the feeding guide trough enter the distributing roller with an accurate posture, facilitating subsequent sensing and identification, and has a wide range of compatible products, which helps improve efficiency.

[0012] Preferably, in the aforementioned automatic sorting device, the first directional sorting and collecting box is equipped with a first height adjustment component, and the second directional sorting and collecting box is equipped with a second height adjustment component. The output ends of both the first and second directional sorting and collecting boxes are equipped with a centerless grinding feed interface for connection with a centerless grinding machine. The first and second height adjustment components can adjust the height of the first and second directional sorting and collecting boxes relative to the grinding machine feed inlet, thereby enabling the sorted products to enter the grinding machine sequentially for grinding. The centerless grinding feed interface facilitates docking of the first and second directional sorting and collecting boxes with the grinding machine.

[0013] Preferably, the aforementioned automatic head-splitting device further includes a control mechanism, which is electrically connected to the sensing and identification mechanism and the head-splitting mechanism. The control mechanism, being signal-connected to the sensing and identification mechanism and the head-splitting mechanism, can control the stepper motor based on the identification result of the sensing and identification mechanism, thereby achieving automatic head splitting.

[0014] Preferably, in the aforementioned automatic splitting device, the product is a spherical tooth product, which has a cylindrical structure, with one end being a spherical arc end and the other end being a chamfered tail end. When the spherical tooth products are arranged axially, there are two placement methods depending on the direction of their ends: one is with the spherical arc end in front and the chamfered tail end behind, and the other is with the chamfered tail end in front and the spherical arc end behind. During subsequent processing, it is necessary to ensure that the product placement method is consistent during feeding; otherwise, it will affect the product processing quality.

[0015] Compared with the prior art, the advantages of this utility model are: This utility model's automatic splitting device can automatically split high-end precision grinding drill bits, specifically ball teeth. The ball teeth are arranged axially in an orderly manner via a feeding mechanism and enter the splitting rollers of the splitting mechanism one by one. After entering the rollers, the end placement direction of the product is identified by a sensing and recognition mechanism. Based on the sensing and recognition results, the rollers transport products with the same end placement direction together and separate products with different end placement directions. For example, products with the head in front and the tail in back are sent to the first direction splitting and collecting box, while products with the tail in front and the head in back are sent to the second direction splitting and collecting box. This achieves continuous automatic splitting of the products, ensuring consistent feeding direction during grinding and balanced automatic feeding. This effectively controls the outer diameter of centerless grinding products, such as ball teeth, significantly improving processing efficiency and quality, reducing the workload of manual operation, and possessing high practical value.

[0016] The automatic splitting device of this utility model solves the problem that the existing technology cannot continuously and automatically maintain the same direction of feeding when machining the outer diameter of ball teeth of high-end precision grinding drill bits of cemented carbide, which leads to the difficulty in controlling the high-precision machining dimensions. Compared with the existing vibratory feeder feeding, which requires manual intervention, resulting in high labor costs, high labor intensity and low labor efficiency, this automatic splitting device has the advantages of compact structure, economical cost and low requirements for the use environment. It can quickly adjust the mating grinding machine and can be applied in batches on existing centerless grinding ball teeth outer diameter equipment. Attached Figure Description

Specifically, the feeding mechanism 2 can arrange multiple products 1 sequentially along the axial direction (length direction) into the distributing roller 31. The function of the sensing and identification mechanism 5 is to identify the orientation of the products 1 on the distributing roller 31, such as whether the head is in front and the tail is behind or the tail is in front and the head is behind. The relevant technology belongs to the prior art, and this is an application of the prior art. That is, any sensing and identification mechanism 5 that can achieve this function in the prior art can be used here, so its working method and working principle will not be described in detail. The first direction distributing and collecting box 32 and the second direction distributing and collecting box 33 can respectively collect products 1 with the spherical arc end in front and the chamfered end at the tail and products 1 with the chamfered end at the tail in front and the spherical arc end at the tail.

The laser sensor 51 can accurately detect whether product 1 enters with a spherical arc end or a chamfered tail end based on the characteristics of spherical tooth products. Based on the detected model, it provides feedback. If a spherical arc end is detected, the dispensing roller 31 rotates to the left to dispense the product; otherwise, it rotates to the right, thus achieving rapid and automatic dispensing.
