Description

Technical Field

[0001] This utility model belongs to the technical field of mechanical parts production equipment, and in particular relates to a mechanical discrimination device for workshop shaft parts. Background Technology

[0002] Automobile production workshops contain a wide variety of shaft parts, such as drive shafts, half shafts, input shafts, output shafts, and intermediate shafts in the drive system production workshop. For shaft parts with large size differences, production workers can accurately and quickly distinguish them; however, for shaft parts with similar sizes, production workers often need to carefully compare them to differentiate them, especially those shaft parts that are small in size.

[0003] Before production, these shaft parts are sorted by type and can be directly used by production staff. However, as production progresses, various shaft parts inevitably become scattered on the production floor. In order to quickly clean up the production floor, production staff will put all these shaft parts together.

[0004] For these shaft parts that are grouped together, careful comparison by production personnel is required to distinguish them, which is time-consuming and labor-intensive. Therefore, they are often directly treated as scrap, resulting in material waste. Based on this, engineers need to design corresponding automatic sorting and recycling equipment for shaft parts. However, because the designed equipment has a certain range of shaft parts that can be recycled, if the operator mistakenly puts in a large-diameter shaft part that exceeds the range, it will cause the equipment to malfunction. Installing a camera recognition device at the input port of the equipment can solve this problem, but this method requires the installation of a host computer and camera on the equipment, which increases the production and maintenance costs of the equipment. Utility Model Content

[0005] In view of the shortcomings of the prior art described above, the purpose of this utility model is to provide a mechanical identification device for shaft parts in the workshop, which solves the problem that the use of camera recognition devices in the prior art requires the installation of a host computer and camera on the automatic classification and recycling equipment for shaft parts, which increases the production and maintenance costs of the equipment.

[0006] To achieve the above and other related objectives, this utility model provides a mechanical discrimination device for workshop shaft parts, installed at the input port of an automatic sorting and recycling equipment for workshop shaft parts, comprising: The inner and outer partitions are both in the shape of "\ / "; A pressure switch is installed on each side of the inner partition and the outer partition, and the height of the pressure switch on the inner partition is lower than the height of the pressure switch on the outer partition. Shaft-type parts entering from the inlet fall between the inner partition and the outer partition; When the shaft part presses the pressure switch on the inner partition, the inner partition opens, and the shaft part enters the entry track of the automatic classification and recycling equipment for shaft parts in the workshop; When the shaft part presses the pressure switch on the outer partition, the outer partition opens, and the shaft part enters the exit of the automatic shaft part sorting and recycling equipment in the workshop.

[0007] As described above, the mechanical discrimination device for workshop shaft parts of this utility model has at least the following beneficial effects: The mechanical sorting device for shaft parts in this workshop uses an inner and outer partition in a " / " shape, with pressure switches installed on opposite sides of both. The height of the pressure switch on the inner partition is lower than that on the outer partition. Shaft parts entering from the inlet fall between the inner and outer partitions. When a shaft part presses the pressure switch on the inner partition, the inner partition opens, and the shaft part enters the entry track of the automatic shaft part sorting and recycling equipment. When a shaft part presses the pressure switch on the outer partition, the outer partition opens, and the shaft part enters the exit outlet of the automatic shaft part sorting and recycling equipment. Compared to existing technologies that use camera recognition devices, which require the installation of a host computer and camera on the equipment, increasing production and maintenance costs, this mechanical sorting device is more reliable, easier to maintain, and lower in cost, and requires no additional operation from production personnel.

[0014] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification.

[0015] Please see Figures 1 to 5 It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes to aid those skilled in the art and are not intended to limit the scope of this invention. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to size, without affecting the effectiveness and purpose of this invention, should still fall within the scope of the technical content disclosed in this invention. Furthermore, the terms such as "upper," "lower," "left," "right," "middle," and "one" used in this specification are merely for clarity and are not intended to limit the scope of this invention. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered within the scope of this invention.

[0016] The following embodiments are for illustrative purposes only. These embodiments can be combined and are not limited to the content shown in any single embodiment below.

[0017] Please see Figure 1 This utility model provides a mechanical identification device for shaft parts in a workshop. Before introducing the device, we will first introduce its application scenario: an automatic sorting and recycling device for shaft parts in a workshop. The device includes: like Figure 1 and Figure 2 The inlet 11 shown is used to receive shaft parts. Production personnel put shaft parts of various diameters that have been produced and put together into this equipment one by one through the inlet 11.

[0018] like Figure 1 The discrimination device 2 shown is used to determine the diameter of shaft-type parts entering the inlet 11. The specific discrimination method will be described below.

[0019] like Figure 2The entry track 3 shown is connected to the input port 11. Shaft-type parts with a diameter smaller than the set value determined by the discrimination device 2 enter the entry track 3. A first gate 31 is provided on it. The structure of the first gate 31 is a horizontal beam placed on the entry track 3. The horizontal beam has a certain distance from the bottom of the entry track 3. A first power component 33 is installed at the first gate 31.

[0020] like Figure 1 and Figure 2 The exit port 12 shown is used by the discrimination device 2 to determine that shaft parts with a diameter greater than or equal to a set value enter the exit port 12, and the production personnel take out the shaft parts from the exit port 12.

[0021] like Figure 2 The first sub-track 61 shown is used by the first power component 33 to feed shaft-like parts that have not passed through the first gate 31 into the first sub-track 61; that is, shaft-like parts with a diameter greater than the interval at the first gate 31 are fed into the first sub-track 61; the first power component 33 can be a hydraulic push rod or the like.

[0022] like Figure 2 The second sub-track 62 shown automatically enters the second sub-track 62 through the shaft-like parts of the first gate 31, that is, shaft-like parts with a diameter smaller than the interval at the first gate 31.

[0023] like Figure 2 The first receiving portion 81 shown houses the shaft-like parts of the first sub-track 61 and has a first outlet.

[0024] like Figure 2 The second receiving portion 82 shown houses the shaft-like parts of the second sub-track 62 and has a second outlet.

[0025] This automatic sorting and recycling equipment for shaft parts in the workshop, equipped with a discrimination device 2, first uses the discrimination device 2 at the input port 11 to determine the diameter of the shaft parts entering the equipment. When the diameter of the shaft part entering the equipment is greater than or equal to a set value, the shaft part exits from the exit port 12, thus preventing operators from mistakenly putting oversized shaft parts into the equipment and causing equipment malfunctions. Then, through the first gate 31 set on the input track 3, shaft parts that pass through the first gate 31 directly enter the second sorting track 62, while shaft parts that do not pass through the first gate 31 enter the first sorting track 61 under the action of the first power component 33. That is, shaft parts of different diameters are automatically sorted. The separated shaft parts are then designed to enter the first receiving part 81 and the second receiving part 82 respectively. This design allows production personnel to remove shaft parts of different diameters separately through the first and second take-out ports without having to carefully compare them, so that shaft parts of different diameters can be sorted and reused separately, reducing material waste.

[0026] In another implementation, please refer to Figure 1 and Figure 2 The device also includes a third sub-track 63, on which a second gate 32 is provided, and a second power component 34 is installed at the second gate 32. The second power component 34 feeds shaft parts that do not pass through the second gate 32 into the third sub-track 63; a third receiving part 83, which receives shaft parts of the third sub-track 63, and has a third outlet; designers can design a fourth track, a fifth track, etc., according to site requirements, which will not be elaborated here.

[0027] In another implementation, please refer to Figure 2 The first sub-track 61 is provided with a first assisting component 611 to assist shaft parts on the first sub-track 61 to enter the first receiving part 81. The first assisting component 611 can be a hydraulic push rod. Similarly, a similar device can be installed on the third sub-track 63.

[0028] In another implementation, please refer to Figure 2 The first accommodating part 81, the second accommodating part 82 and the third accommodating part 83 are all "Z"-shaped slides, which ensures that more shaft parts can be accommodated when the shaft parts are arranged in an orderly manner.

[0029] In another implementation, please refer to Figure 1 The device also includes a housing 1, on which the inlet 11 is opened. The entry rail 3, the first sub-rail 61, the second sub-rail 62, the first accommodating part 81 and the second accommodating part 82 are all installed in the housing 1. The housing 1 also includes wire harnesses, etc. The housing 1 provides necessary protection for various components.

[0030] In another implementation, please refer to Figure 1 The box 1 is equipped with a box door 13, which is detachable. The box door 13 is opposite to the first take-out outlet, the second take-out outlet, and the third take-out outlet. Each of the first take-out outlet, the second take-out outlet, and the third take-out outlet is detachably equipped with a baffle 84. After all the parts on the production site are put into the equipment, or after the first accommodating part 81, the second accommodating part 82, and the third accommodating part 83 are full, the staff will first open the box door 13 and then open the baffle 84 to take out the shaft parts from the three accommodating parts respectively.

[0031] In another implementation, please refer to Figure 1 The box 1 is equipped with an identification frame 4. Multiple units of this equipment can be produced according to the needs of on-site production. Each unit can store shaft parts with different diameter ranges. Identification signs are installed on the identification frame 4, indicating the storage range of the equipment.

[0032] In another implementation, please refer to Figure 2 The first accommodating part 81, the second accommodating part 82, and the third accommodating part 83 are all spaced from the inner wall of the housing 1 to facilitate cleaning and to accommodate wire harnesses, etc.

[0033] In another implementation, please refer to Figure 1 The top of the box 1 is open, and the tops of the first accommodating part 81, the second accommodating part 82, and the third accommodating part 83 are also open. This not only makes it convenient for staff to observe the number of shaft parts contained in the three accommodating parts, but also, combined with the detachable box door 13, makes it convenient for staff to clean and maintain the inside of the box 1.

[0034] In another implementation, please refer to Figure 2 Vibration components are installed on the first receiving part 81, the second receiving part 82, and the third receiving part 83 to ensure that shaft parts slide smoothly to the bottom in the "Z"-shaped slide.

[0035] In other implementations, such as Figure 1 As shown, a handle 14 can be designed on the door 13, and a foot pad 15 can be designed on the bottom of the box body 1; the "Z"-shaped slide can be designed with an arc-shaped recess according to the size of the shaft parts, so as to realize the track-based movement of the shaft parts.

[0036] Please see Figure 1 , Figure 3 and Figure 4 The mechanical discrimination device 2 will be described below. Installed at the input port 11, it differs from existing technologies that use camera recognition devices, which require the installation of a main unit and camera on the equipment, increasing production and maintenance costs. The mechanical discrimination device 2 is more reliable, easier to maintain, and lower in cost, and requires no additional operation from production personnel. The discrimination device 2 includes: like Figure 3 and Figure 4 The inner partition 21 and outer partition 22 shown are in the shape of "\ / ". A pressure switch 5 is installed on the opposite side of the inner partition 21 and the outer partition 22. The height of the pressure switch 5 on the inner partition 21 is lower than the height of the pressure switch 5 on the outer partition 22. That is, small-diameter shaft parts press the pressure switch 5 on the lower-height inner partition 21, and large-diameter shaft parts press the pressure switch 5 on the higher-height outer partition 22.

[0037] like Figure 3As shown, shaft parts entering from the inlet 11 fall between the inner partition 21 and the outer partition 22; when the shaft parts press the pressure switch 5 on the inner partition 21, the inner partition 21 opens, and the shaft parts enter the inlet track 3; when the shaft parts press the pressure switch 5 on the outer partition 22, the outer partition 22 opens, and the shaft parts enter the outlet 12.

[0038] In another implementation, please refer to Figure 3 and Figure 4 The discrimination device 2 also includes a discrimination chamber 23, with both ends of the lower edge of the inner partition 21 and both ends of the lower edge of the outer partition 22 hinged to the inner wall of the discrimination chamber 23; when the shaft part presses the pressure switch 5 on the inner partition 21, the inner partition 21 rotates around its lower edge toward the entry track 3, and the shaft part enters the entry track 3; when the shaft part presses the pressure switch 5 on the outer partition 22, the outer partition 22 rotates around its lower edge toward the exit port 12, and the shaft part enters the exit port 12; this embodiment provides a specific structural form for opening the inner partition 21 and the outer partition 22.

[0039] In another embodiment, the pressure switch 5 includes: like Figure 5 The switch base 51 shown is fixedly installed.

[0040] like Figure 5 The switch spring 52 shown is mounted on the switch base 51; a spring post can be provided on the switch base 51 to ensure that the switch spring 52 does not shift when it is compressed and rebounds.

[0041] like Figure 5 The rack 53 shown has its bottom end connected to the switch spring 52, and its top end fixed with a button 54, which is located on the opposite side of the inner partition 21 and the outer partition 22; similarly, a spring post can also be provided at the bottom end of the rack 53.

[0042] like Figure 5 The first gear 55 shown meshes with the rack 53.

[0043] like Figure 5 The second gear 56 shown is a toothed gear. The toothed part meshes with the first gear 55. The toothed part is fixed with a retaining strip 57, which extends toward the inner wall of the discrimination chamber 23.

[0044] When no external force is applied to the button 54, the outer end of the card strip 57 abuts against the inner wall of the discrimination chamber 23.

[0045] When the button 54 is pressed by external force, the rack 53 moves, driving the first gear 55 to rotate. The first gear 55 drives the second gear 56 to rotate, which in turn drives the retaining strip 57 to rotate. The outer end of the retaining strip 57 disengages from the inner wall of the discrimination chamber 23. The inner partition 21 and the outer partition 22 lose contact with the inner wall of the discrimination chamber 23, thus rotating and opening the inner partition 21 and the outer partition 22. When the pressure on the button 54 is released, under the action of the spring force, the retaining strip 57 rotates back and re-engages with the inner wall of the discrimination chamber 23. The inner partition 21 or the outer partition 22 no longer rotates. As the retaining strip 57 rotates, it will drive the outer partition 22 or the inner partition 21 back to the closed position. If the outer partition 22 and the inner partition 21 do not return to the closed position, the production personnel can adjust them manually.

[0046] In another implementation, please refer to Figure 4 The inner wall of the discrimination chamber 23 is provided with a slot 231. When no external force is applied to the button 54, the outer end of the locking strip 57 abuts against the slot 231. A protrusion can be provided on the slot 231 to cooperate with the locking strip 57 to ensure the stability of the inner partition 21 and the outer partition 22 when they are closed.

[0047] In another implementation, please refer to Figure 4 The slot 231 extends to the edge of the inner wall of the discrimination chamber 23 to facilitate processing.

[0048] In another implementation, please refer to Figure 5 The pressure switch 5 also includes a switch housing 58, which is fixed to the inner partition 21 or the outer partition 22. The rack 53, the switch spring 52, the switch base 51, the first gear 55, and the second gear 56 are all installed in the switch housing 58. When no external force is applied to the button 54, the button 54 protrudes from the switch housing 58. When an external force presses the button 54, the button 54 enters the switch housing 58. The retaining strip 57 extends out of the switch housing 58. The design of the switch housing 58 provides protection for the various components of the pressure switch 5.

[0049] In other implementations, such as Figure 3 and Figure 4 As shown, two pressure switches 5 at the same height are installed on the inner partition 21, and the two locking strips 57 of the two pressure switches 5 extend toward the inner wall of the discrimination chamber 23 at both ends of the inner partition 21, respectively; two pressure switches 5 at the same height are installed on the outer partition 22, and the two locking strips 57 of the two pressure switches 5 extend toward the inner wall of the discrimination chamber 23 at both ends of the outer partition 22, respectively; the design of two pressure switches 5 on the outer partition 22 and the inner partition 21, respectively, further improves the working stability of the discrimination device 2.

[0050] In summary, this utility model, with its inner partition 21 and outer partition 22 arranged in a " / " shape, and each side equipped with a pressure switch 5, features a lower height for the pressure switch 5 on the inner partition 21 than on the outer partition 22. Shaft-like parts entering through the inlet 11 fall between the inner and outer partitions. When the shaft-like parts press the pressure switch 5 on the inner partition 21, the inner partition 21 opens, allowing the shaft-like parts to enter the entry track 3 of the automatic shaft-like parts sorting and recycling equipment. When the shaft-like parts press the pressure switch 5 on the outer partition 22, the outer partition 22 opens, allowing the shaft-like parts to enter the exit outlet 12 of the automatic shaft-like parts sorting and recycling equipment. Compared to existing technologies using camera recognition devices that require the installation of a main unit and camera on the equipment, increasing production and maintenance costs, this mechanical discrimination device 2 is more reliable, easier to maintain, and lower in cost, requiring no additional operation from production personnel. Therefore, this utility model effectively overcomes the shortcomings of existing technologies and has high industrial application value.

[0051] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
