[0001] This utility model relates to the field of polishing technology, and in particular to a surface polishing device for titanium and titanium alloy rods. Background Technology

[0002] Titanium and titanium alloy rods are widely used in many fields due to their superior properties. During the production and processing, oxide scale easily forms on their surface, which affects the appearance and performance of the product. Therefore, titanium and titanium alloy rods need to be polished to remove oxide scale and improve their mirror finish.

[0003] Currently, common polishing methods include mechanical polishing, barrel polishing, chemical polishing, and electrolytic polishing. Mechanical polishing is favored by the market due to its ease of operation and high safety factor. However, due to the uneven thickness of the oxide scale on the surface of titanium rods, existing mechanical polishing equipment has difficulty in accurately controlling the polishing depth, resulting in low precision after polishing, which is difficult to meet the requirements of high-precision applications. Utility Model Content

[0004] In order to overcome the shortcomings of the above-mentioned background technology, the present invention provides a high-efficiency and high-precision surface polishing device for titanium and titanium alloy rods.

[0005] The technical solution of this utility model is: a surface polishing device for titanium and titanium alloy rods, including a rough grinding machine and a fine grinding machine. The feed inlet of the rough grinding machine is connected to a first feed conveyor belt, and the discharge outlet is connected to a first discharge conveyor belt. The feed inlet of the fine grinding machine is connected to a second feed conveyor belt, and the discharge outlet is connected to a second discharge conveyor belt. The height of the first discharge conveyor belt is greater than that of the second feed conveyor belt. The side baffles on the opposite side of the first discharge conveyor belt and the second feed conveyor belt are respectively provided with first side notches. The two first side notches are connected by inclined plates. A discharge stop bar is provided at the first side notch of the first discharge conveyor belt. The material conveying direction of the first discharge conveyor belt is opposite to that of the second feed conveyor belt. A diameter measuring instrument is also provided above the second discharge conveyor belt.

[0006] Furthermore, the input end of the first feeding conveyor belt is connected to the feeding assembly, which includes a support leg, a hopper, and a feeding cylinder. The hopper is located at the upper end of the support leg, and the longitudinal section of the hopper is an inverted triangular structure. The upper end of the hopper is open, and the bottom two side walls are respectively provided with feeding holes that extend along their length. A feeding cylinder is installed in the feeding hole of one side wall, and the feeding hole of the other side wall is connected to the input end of the first feeding conveyor belt.

[0007] Furthermore, the output end of the second discharge conveyor belt is connected to the unloading assembly, which includes a dropping plate, a receiving box, and an unloading wheel. A second side notch is provided at the side baffle of the second discharge conveyor belt. The dropping plate is located at the second side notch and tilts downward. The receiving box is located at the lower end of the dropping plate. The unloading wheel includes a support plate on the frame of the second discharge conveyor belt, a motor and a flywheel located at the upper end of the support plate. Multiple clamps are arranged circumferentially on the outer side of the flywheel. The axis of the flywheel is consistent with the length direction of the second discharge conveyor belt. The motor is connected to the flywheel for transmission. When the flywheel stops, the clamps rest on the upper side of the second discharge conveyor belt, and the blank material can just fill the clamps.

[0008] Furthermore, the diameter measuring instrument is a CCD diameter measuring instrument, used to measure whether the size of the blank is qualified. It is set between the unloading assembly and the fine grinding machine. There are two opposite openings on the second side, and two corresponding receiving boxes are provided. One receiving box is used to receive qualified blanks, and the other receiving box is used to receive unqualified blanks.

[0009] Furthermore, baffles are provided on both sides of the inclined plate, and the baffles are adjustablely clamped onto the inclined plate by a clamp.

[0010] Furthermore, it also includes an air dryer, which includes a pipe installed at the discharge end of the fine grinding machine, one end of which points to the upper surface of the second discharge conveyor belt, and the other end is connected to an air compressor.

[0011] Furthermore, the conveyor belt is a herringbone patterned conveyor belt.

[0012] The beneficial effects are:

[0013] 1. This invention, by setting up a rough grinding machine and a fine grinding machine, and utilizing a first discharge conveyor belt and a second feed conveyor belt connected by an inclined plate in opposite directions, allows the titanium rod to be conveyed to the fine grinding machine in a circuitous manner after rough polishing, effectively shortening the processing line length and reducing space occupation. The staged processing of rough and fine grinding significantly improves polishing accuracy. Simultaneously, a discharge stop is installed at the notch of the first discharge conveyor belt to facilitate control of the titanium rod feeding process. Furthermore, a diameter gauge above the second discharge conveyor belt can be used to monitor the dimensions of the polished titanium rod in real time, thereby improving the product qualification rate. This invention not only optimizes the polishing process but also improves production efficiency and product quality.

[0014] 2. This utility model connects the input end of the first feeding conveyor belt to the feeding assembly, enabling automatic and stable feeding of titanium and titanium alloy rods into the rough grinding machine, saving labor costs while improving production efficiency and feeding accuracy. The inverted triangular structure of the hopper facilitates smooth sliding of the billet, and its open top allows for rapid and batch addition of billets. The feeding hole at the bottom fits tightly with the first feeding conveyor belt. A feeding cylinder installed in the feeding hole on one side wall provides stable thrust, ensuring that the billets enter the conveyor belt in an orderly manner.

[0015] 3. This utility model features a material unloading component at the output end of the second discharge conveyor belt, enabling the polished titanium rods to be unloaded systematically on the conveyor belt. An inclined drop plate guides the titanium rods smoothly to the receiving box, facilitating collection and transfer, reducing manual intervention. The flywheel's clamp is size-matched to the titanium rods; under motor control, when the flywheel pauses, the clamp rests precisely on the upper side of the second discharge conveyor belt, accurately filling the blank into the clamp, achieving efficient and accurate material unloading.

[0016] 4. The diameter measuring instrument of this utility model adopts a CCD diameter measuring instrument and is set between the unloading assembly and the fine grinding machine. It can measure the size of the blank in real time and accurately, with the error controlled within a very small range. Its position setting facilitates the accurate screening of blanks with unqualified dimensions before fine grinding, and diverts them to the unqualified receiving box in advance.

[0017] 5. This utility model features adjustable baffles on both sides of the inclined plate, effectively preventing the titanium bars from slipping due to gravity or inertia during the inclined plate conveying process, ensuring that the titanium bars transition stably and safely from the first discharge conveyor belt to the second feed conveyor belt. The adjustability of the clamps allows it to adapt to the conveying needs of titanium bars of different specifications.

[0018] 6. The air dryer of this utility model delivers high-speed airflow to the second discharge conveyor belt through a pipe connected to an air compressor, which can promptly dry the coolant or moisture remaining on the surface of the polished titanium rod, thus preventing water stains from appearing on the surface of the titanium rod due to moisture residue.

Detailed Implementation

[0023] The preferred technical solution of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] like Figure 1-3 The surface polishing device for titanium and titanium alloy rods shown includes a rough grinding machine 1, a fine grinding machine 2, and multiple transmission belts. The feed inlet of the rough grinding machine 1 is connected to a first feed conveyor belt 3, and the discharge outlet is connected to a first discharge conveyor belt 31. The feed inlet of the fine grinding machine 2 is connected to a second feed conveyor belt 32, and the discharge outlet is connected to a second discharge conveyor belt 33. The conveyor belts are preferably herringbone conveyor belts, which can provide stable gripping force during the conveying of titanium rod blanks, ensuring that the titanium rod blanks are accurately conveyed to each processing station at a predetermined speed and direction. The titanium rod blanks are processed by the rough grinding machine 1 to remove excess material, and then processed by the fine grinding machine 2 to ensure the final dimensions. In order to shorten the processing line length, in this embodiment, the rough grinding machine 1 and the fine grinding machine 2 are installed side by side. By setting the conveying direction of the first discharge conveyor belt 31 to be opposite to the conveying direction of the second feed conveyor belt 32, the blanks are directly transferred to the fine grinding machine 2 after detours by the conveyor belts, effectively reducing the space occupancy rate.

[0025] refer to Figure 1 To improve the feeding efficiency of this device, an automatic feeding assembly 6 is connected to the input end of the first feeding conveyor belt 3. This feeding assembly 6 consists of a support leg 61, a hopper 62, and a feeding cylinder 63. The hopper 62 is located above the support leg 61 and has an inverted triangular cross-section. The upper end of the hopper 62 is open, and each of its two bottom side walls has a feeding hole extending along its length. A feeding cylinder 63 is installed in one of the feeding holes on one side wall, and the feeding hole on the other side wall is connected to the input end of the first feeding conveyor belt 3. Titanium billets placed in the hopper 62 are pushed forward by the feeding cylinder 63 and transferred along the feeding hole to the first feeding conveyor belt 3. The top titanium billets automatically move downwards due to their own weight. Repeated pushing by the feeding cylinder 63 achieves automatic feeding of the titanium billets.

[0026] For details, please refer to [link / reference]. Figure 2The side baffles on the opposite side of the first discharge conveyor belt 31 and the second feed conveyor belt 32 are respectively provided with first side openings, and an inclined plate 4 is connected to the two first side openings. A discharge baffle 41 is provided at the opening of the first discharge conveyor belt 31. The height of the first discharge conveyor belt 31 is greater than that of the second feed conveyor belt 32, which allows the titanium rods to be transferred from the first discharge conveyor belt 31 to the second feed conveyor belt 32 along the inclined plate 4. The discharge baffle 41 allows the titanium rod blanks conveyed along the first discharge conveyor belt 31 to be smoothly unloaded from the first discharge conveyor belt 31. Specifically, after the titanium rod blanks on the first discharge conveyor belt 31 come into contact with the discharge baffle 41, their contact area with the first discharge conveyor belt 31 gradually decreases, and eventually they completely detach from the first discharge conveyor belt 31.

[0027] In addition, it should be noted that the discharge stop bar 41 is installed at the first side opening of the first discharge conveyor belt 31 by a clamp, and its position can be adjusted according to the length of the titanium billet. Furthermore, baffle plates 42 are respectively provided on both sides of the inclined plate 4 to limit the position of the titanium billet and prevent it from slipping due to gravity or inertia during the transfer and conveying process on the inclined plate 4. In addition, the baffle plates 42 are adjustablely clamped on the inclined plate 4 by a clamp, thereby accommodating titanium billets of different lengths.

[0028] like Figure 3 As shown, after the titanium rod billet is processed by the precision grinding machine 2, it is unloaded along the second discharge conveyor belt 33. The diameter gauge 5 is installed above the second discharge conveyor belt 33. The diameter gauge 5 is preferably a high-speed CCD diameter gauge 5. The diameter gauge 5 is used to measure whether the billet size is qualified. It is set between the unloading assembly 7 and the precision grinding machine 2. After the titanium rod billet is precision ground, the surface is adhered with grinding fluid or coolant. At this time, it will cause slight interference during measurement. Therefore, a dryer is also installed before the diameter gauge 5. It includes a pipe 8 set at the discharge end of the precision grinding machine 2. One end of the pipe 8 points to the upper surface of the second discharge conveyor belt 33, and the other end is connected to the air compressor.

[0029] The titanium billet measured by the diameter gauge 5 has two results: qualified and unqualified. A material return assembly 7 is installed at the output end of the second discharge conveyor belt 33 to receive the titanium billet. The material return assembly 7 includes a dropping plate 71, a receiving box 72, and a material return wheel 73. A second side notch is provided at the side baffle of the second discharge conveyor belt 33. Specifically, in this embodiment, two opposite second side notches are provided, and two receiving boxes 72 are also provided. One receiving box 72 is used to receive qualified billets, and the other receiving box 72 is used to receive unqualified billets. Specifically, the dropping plate 71 is located at the second side notch and tilted downwards, and the receiving box 72 is located at the bottom of the dropping plate 71.

[0030] The ejector wheel 73 consists of a support plate 731, a motor 732, and a flywheel 733. The lower end of the support plate 731 is fixed to the frame of the second discharge conveyor belt 33, and the upper end of the support plate 731 is equipped with the motor 732 and the flywheel 733. The flywheel 733 is connected to the shaft of the motor 732 for transmission. Multiple clamps 734 are arranged circumferentially along the outer side of the flywheel 733. The axial direction of the flywheel 733 is consistent with the length direction of the second discharge conveyor belt 33. When the flywheel 733 stops, the clamps 734 stop on the upper side of the second discharge conveyor belt 33, and the blank material can just fill the clamps 734. The motor 732 is linked with the diameter gauge 5 and controlled by the controller. When the diameter gauge 5 detects that the blank material is of qualified size, the motor 732 rotates and drives the blank material from the second discharge conveyor belt 33 to the drop plate 71 through the clamps 734, and then slides into the corresponding receiving box 72. Furthermore, when the diameter gauge 5 detects that the blank size is unqualified, the motor 732 rotates in another direction to transfer the blank to another receiving box 72 for collection. Compared with traditional polishing devices, this device improves the production efficiency and product accuracy, making it more suitable for automated and refined production needs.

[0031] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the inventive concept, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
