Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a workpiece tapping device. Background Art

[0002] Multi-axis tapping machines can process several or even dozens of holes or threads at a time. If equipped with hydraulic or CNC devices, they can automatically perform fast forward, working forward (working backward), fast backward, and stop. The cost and efficiency are better than those of machining centers. Multi-axis tapping machines can tap two to twenty-five holes at the same time, which greatly improves efficiency. The number of axes of fixed models is not limited, and the form and size of drilling axes can be designed and processed according to customer needs. Multi-axis tapping machines are widely used in drilling and tapping processing of parts in the machinery industry. Multi-axis tapping machines can be divided into two specifications: adjustable and fixed. Within the processing range of adjustable multi-axis tapping machines, the number of spindles and the distance between spindles can be adjusted relatively arbitrarily. Several holes can be processed at the same time with one feed. Compared with single-axis drilling (tapping), the workpiece processing accuracy is high and the work efficiency is fast, which can effectively save the manpower, material and financial resources of the investor. In particular, the automation of machine tools greatly reduces the labor intensity of operators. The fixed multi-axis tapping machine adopts the design of a single-piece (processing part) special machine. Due to the high frequency and large quantity of processing parts, the equipment is specially tailored for one piece and one machine. There is no need to worry about the size deviation during work. In addition to using conventional products, special designs can also be carried out according to the special requirements of customers.

[0003] At present, most tapping machines are not fully automated. The tapping mechanism of the tapping machine cannot automatically complete the tapping action, but the loading and unloading of the product requires manual operation: the products are manually clamped in the fixture of the tapping machine one by one before tapping, and the products are manually removed after tapping. Due to the limited action speed of manual clamping, the overall efficiency of the tapping process is low, and it consumes manpower. At the same time, the positioning accuracy of the product cannot be guaranteed during manual clamping, so the quality of the product after tapping is unstable. Utility Model Content

[0030] See also Figures 1 to 4 , is a workpiece tapping device in some embodiments of the utility model, which includes a frame 1, a pair of positioning and conveying mechanisms 3 arranged on the frame 1 and used for positioning and conveying the workpiece 2, a tapping mechanism 4 for tapping the workpiece 2 and a collecting part 5. The tapping mechanism 4 can be a multi-axis tapping machine, which can simultaneously process threaded holes of multiple workpieces 2. The multi-axis tapping machine is a mature product of the prior art, and different models and specifications of multi-axis tapping machines can be selected according to actual needs.

[0031] like Figure 2As shown, the pair of positioning and conveying mechanisms 3 are symmetrically arranged about the center plane of the frame 1, and each positioning and conveying mechanism 3 includes a silo assembly 31 installed on the frame 1 and used to store the workpiece 2, a transport assembly 32 installed on the frame 1, and a positioning assembly 33 connected to the transport assembly 32. The transport assembly 32 is used to receive the workpiece 2 provided by the silo assembly 31 and transport the workpiece 2 to the positioning assembly 33, the positioning assembly 33 is used to fix the workpiece 2, the tapping mechanism 4 taps the workpiece 2 fixed on the positioning assembly 33, and the collecting member 5 is used to receive the workpiece 2 after being tapped by the tapping mechanism 4.

[0032] It can be understood that the workpiece tapping device utilizes the silo component 31 to store the workpiece 2 and provides the workpiece 2 to the transport component 32, and the transport component 32 can automatically transport the workpiece 2 to the positioning component 33. After the positioning component 33 fixes the workpiece 2, the tapping mechanism 4 performs the tapping operation. The tapping mechanism 4 can process two workpieces 2 at the same time. The workpiece tapping device improves the automation level of the tapping of the workpiece 2, reduces manual operation, and improves production efficiency.

[0033] like Figure 3 As shown, the silo assembly 31 includes a silo positioning frame 311 installed on the frame 1, a main silo 312 provided on the silo positioning frame 311 and used to store unprocessed workpieces 2, and a guide plate 313 provided at the bottom of the main silo 312. The unprocessed workpieces 2 enter the transport assembly 32 from the main silo 312 through the guide plate 313. The workpieces 2 to be processed can be placed in the main silo 312 in large quantities in advance.

[0034] In addition, the silo assembly 31 also includes a vibration motor 314 disposed on the silo positioning frame 311 and connected to the bottom of the guide plate 313, and a weight sensor disposed on the main silo 312. The vibration motor 314 can facilitate the unloading of the workpiece 2, and the weight sensor can measure the total weight of the workpiece 2 stored in the main silo 312. The measurement of the total weight allows the staff to understand the working status in time, and replenish the material in time when the total weight is insufficient.

[0035] like Figure 2 and Figure 4 As shown, the transport assembly 32 includes a vibration plate 321 installed on the frame 1 and used to receive the workpiece 2 flowing out through the guide plate 313, a conveyor frame 322 connected to the vibration plate 321, and an infrared sensor 323 installed on the conveyor frame 322. The vibration plate 321 is an auxiliary feeding equipment for automatic assembly or automatic processing machinery, which can arrange various products in an orderly manner, cooperate with automatic assembly equipment to assemble various parts of the product into a complete product, or cooperate with automatic processing machinery to complete the processing of the workpiece 2.

[0036] Specifically, the conveyor frame 322 is connected to the output end of the vibration plate 321, and the conveyor frame 322 is vertically arranged relative to the horizontal plane. The conveyor frame 322 is provided with a positioning groove 3221 for positioning the workpiece 2. The shape of the positioning groove 3221 matches the shape of the workpiece 2. When the workpiece 2 flows into the positioning groove 3221 through the vibration plate 321, the workpiece 2 moves downward along the positioning groove 3221. The conveyor frame 322 is also provided with a vibrator 3222 to facilitate material unloading and prevent the workpiece 2 from getting stuck in the positioning groove 3221.

[0037] The infrared sensor 323 is a sensor that uses the physical properties of infrared rays for measurement. Infrared rays are also called infrared light. They have properties such as reflection, refraction, scattering, interference, and absorption. Any substance can radiate infrared rays as long as it has a certain temperature above absolute zero. The infrared sensor does not directly contact the object being measured during measurement, so there is no friction, and it has the advantages of high sensitivity and fast response. The infrared sensor 323 is specifically used to detect the workpiece 2. The infrared sensor 323 is set at a certain height on the conveyor frame 322. When the infrared sensor 323 senses the workpiece 2, the vibration plate 321 stops unloading to prevent excessive accumulation of workpieces 2.

[0038] like Figure 4 As shown, the positioning assembly 33 includes a fixing member 331, a first cylinder 332 and an action plate 333. The fixing member 331 is connected to the bottom of the conveying frame 322, and the fixing member 331 is provided with a fixing groove 3311 connected to the positioning groove 3221. The first cylinder 332 is connected to the bottom of the fixing member 331, and the action plate 333 is connected to the output end of the first cylinder 332 and is used to push the workpiece 2 in the fixing groove 3311.

[0039] The positioning assembly 33 further includes a second cylinder 334, a third cylinder 335 and a limiting plate 336. The second cylinder 334 is connected to the side end surface of the retaining member 331, the third cylinder 335 is connected to the top end surface of the retaining member 331, and the limiting plate 336 is connected to the output end of the third cylinder 335. When the first cylinder 332 pushes the workpiece 2 from the first end of the retaining groove 3311 to the second end of the retaining groove 3311, the second cylinder 334 cooperates with the limiting plate 336 to fix the position of the workpiece 2. The positioning assembly 33 further includes a fourth cylinder 337 connected to the retaining member 331, and the fourth cylinder 337 is used to push the workpiece 2 to fall into the collecting member 5.

[0040] In general, when the positioning assembly 33 is in working state, when the workpiece 2 flows from the positioning groove 3221 to the retaining groove 3311, the first cylinder 332 pushes the action plate 333, so that the workpiece 2 located in the retaining groove 3311 is pushed from the first end of the retaining groove 3311 to the second end of the retaining groove 3311, and the first cylinder 332 drives the action plate 333 to return to the initial state, and then the third cylinder 335 drives the limit plate 336 to move downward, and the limit plate 336 is located in the retaining groove 3311. Then, the output end of the second cylinder 334 is used to move toward the direction of the action plate 333, and the output end of the second cylinder 334 cooperates with the limit plate 336 to fix the workpiece 2. After the workpiece 2 is fixed, the tapping mechanism 4 can be used to perform tapping processing on the workpiece 2. When the workpiece 2 is processed, the third cylinder 335 drives the limit plate 336 to move upward and return to its initial state. At this time, the output end of the second cylinder 334 pushes the workpiece out to the retaining groove 3311 in the lower space of the limit plate 336, and then the second cylinder 334 retreats. At this time, the fourth cylinder 337 pushes upward, thereby pushing the workpiece 2 to fall into the aggregate 5 to complete the processing.

[0041] In addition, the positioning assembly 33 further includes a connecting frame 338, and the retaining member 331 is connected to the frame 1 via the connecting frame 338. The retaining member 331 and the connecting frame 338, and the connecting frame 338 and the frame 1 can be connected by bolts.

[0042] It can be understood that the above embodiments only express the preferred implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the patent scope of the utility model. It should be pointed out that, for ordinary technicians in this field, without departing from the concept of the utility model, the above-mentioned technical features can be freely combined, and several deformations and improvements can be made, which all belong to the protection scope of the utility model. Therefore, all equivalent changes and modifications made to the scope of the claims of the utility model should fall within the scope of the claims of the utility model.
