Description

Technical Field

[0001] This utility model belongs to the field of scraping and grinding, and specifically relates to a scraping and grinding testing device for scraping and grinding assemblies. Background Technology

[0002] Scraping is an on-site assembly process that improves the geometric accuracy of parts through scraping and measurement. Scraping can create tiny pits on the surface of parts, improving oil retention and reducing friction. Scraping can be flexibly applied in various scenarios and is not limited by the dimensions of traditional machining.

[0003] When scraping the edge of a workpiece using a scraping machine, the scraper blade is prone to colliding with the edge of the workpiece, which can damage the workpiece. The current way to avoid this is to rely on human experience and judgment, combined with visual observation and the hand's feeling of cutting resistance to achieve fine processing of the workpiece edge. However, on the one hand, human judgment leads to low workpiece edge processing accuracy, and on the other hand, human judgment also leads to low processing efficiency. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a scraping inspection device for scraping assemblies, aiming to enable the automatic detection of the contour features of the workpiece, avoid collisions between the scraping tool and the workpiece edge, and thus better protect the workpiece.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A scraping inspection device for scraping assemblies includes a fixing plate, a housing is fixedly connected to the bottom of the fixing plate, a scraping blade assembly is installed at the bottom of the housing and the scraping blade assembly has a scraping blade, the housing has a housing chamber that extends along the extension direction of the housing itself and is open to one side. A fixing seat is installed at the bottom of the fixing plate. The fixing seat is installed inside the housing chamber and extends downward. One outer side wall of the fixing seat extends out of the housing through an opening in the side wall of the housing chamber. An optical fiber sensor is fixedly connected to the position where the fixing seat extends out of the housing. The focusing lens connected to the optical fiber sensor extends downward in a vertical direction, and the bottom end of the focusing lens corresponds to the through hole on the scraper. An optical fiber amplifier is also installed on the housing, and the optical fiber amplifier is optically coupled to the optical fiber sensor.

[0006] Preferably, the through hole is formed at the edge of the scraper.

[0007] Preferably, the scraper is made of hard alloy material.

[0008] Preferably, the lower end of the fiber optic sensor is connected to the top of the focusing lens via a thread.

[0009] Preferably, the fixing seat has a fixing seat chamber inside, which opens upward.

[0010] Preferably, the top of the fixing seat has a fixing seat connecting part that matches the fixing plate, and the fixing seat connecting part is fixed to the fixing plate by bolts.

[0011] Preferably, the housing chamber extends along the bottom of the housing and is open, a constant force cylinder is fixedly connected to the bottom of the fixed seat, and the constant force cylinder is located inside the housing chamber. The free end of the constant force cylinder extends downward until it extends out of the housing chamber through the opening at the bottom of the housing chamber and is connected to the scraper rod assembly shown.

[0012] Preferably, the free end of the constant force cylinder is fixedly mounted on the scraper rod assembly by bolts.

[0013] Preferably, a constant force cylinder is fixedly connected to the bottom of the fixed base by bolts.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. Due to the cooperation of the fiber optic sensor, fiber optic amplifier, and focusing lens in this utility model—namely, the optical path coupling between the fiber optic amplifier and the fiber optic sensor, the cooperation between the focusing lens connected to the fiber optic sensor, and the cooperation between the focusing lens and the through hole on the scraper—the light spot generated by the fiber optic sensor and the focusing lens can be used to determine whether the light spot illuminates the workpiece surface through the through hole on the scraper. If so, the fiber optic amplifier will output a high-level signal, indicating that there is a workpiece under the scraper, and the scraper will not collide with the edge of the workpiece when it moves forward. Conversely, if there is no workpiece under the scraper, the fiber optic amplifier will output a low-level signal, indicating that there is no workpiece under the scraper, and the scraper may collide with the edge of the workpiece when it moves forward. This allows for the automatic detection of the workpiece's contour features, preventing the scraper from colliding with the workpiece edge and thus better protecting the workpiece.

[0015] 2. In this utility model, when the fiber optic sensor, fiber optic amplifier and focusing lens drive the scraping knife to determine whether it collides with the edge of the workpiece in Embodiment 1, the constant force cylinder on the device is then driven so that the free end of the constant force cylinder can control the scraping knife assembly with constant pressure. Specifically, the constant force cylinder can achieve constant pressure control, which facilitates the subsequent scraping operation of the workpiece, that is, ensures the consistency of scraping depth.

[0018] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following embodiments are described in detail with reference to the accompanying drawings. It should be noted that the description of these embodiments is for the purpose of helping to understand this utility model, but does not constitute a limitation on this utility model.

[0019] Example 1 like Figure 1-5 As shown, a scraping inspection device for scraping assembly includes a fixing plate 11, a housing 1 fixedly connected to the bottom of the fixing plate 11, a scraping blade assembly 2 installed at the bottom of the housing 1, and the scraping blade assembly 2 having a scraping blade 3 made of hard alloy material. The housing 1 has a housing chamber that extends along the extension direction of the housing 1 itself and is open to one side. A fiber optic sensor 6 is fixedly connected to the outer wall of the mounting base 4. The focusing lens 7 connected to the fiber optic sensor 6 extends vertically downwards, and the bottom end of the focusing lens 7 corresponds to the through hole 8 on the scraper blade 3 (and the through hole 8 is opened at the edge of the scraper blade 3). A fiber optic amplifier 9 is also installed on the housing 1, and the fiber optic amplifier 9 is optically coupled to the fiber optic sensor 6. The purpose is that the fiber optic sensor 6, in conjunction with the focusing lens 7, can generate a light spot with a diameter of about 0.5 mm. When the light spot shines on the surface of the workpiece 10 through the through hole 8 on the scraper blade 3 (at this time, the workpiece 10 is preset on a fixed device and located below this detection device, specifically, the workpiece 10 is located below the scraper blade 3), the fiber optic amplifier 9 will output a high-level signal, which indicates that there is a workpiece 10 below the scraper blade 3 (e.g., Figure 3As shown), the scraper 3 will not collide with the edge of the workpiece 10 when it moves forward; When the light spot passes through the through-hole 8 on the scraper blade 3 and does not illuminate the workpiece 10, the fiber optic amplifier 9 will output a low-level signal, indicating that there is no workpiece 10 below the scraper blade 3 (e.g., Figure 4 As shown, the scraping blade 3 may collide with the edge of the workpiece 10 when it moves forward. The scraping path of the scraping assembly 2 is adjusted in real time by the operating system attached to this device so that the contour features of the workpiece 10 can be automatically detected and the scraping blade 3 can be prevented from colliding with the edge of the workpiece in order to better protect the workpiece 10.

[0020] In addition, to make the mounting base 4 lighter, a mounting base chamber is provided inside the mounting base 4, which opens upward.

[0021] Example 2 Based on Example 1, the following operations are performed on this device: like Figure 6 As shown, a fixing seat 4 is installed at the bottom of the fixing plate 11 (specifically, the top of the fixing seat 4 has a fixing seat connecting part 41 that matches the fixing plate 11, and the fixing seat connecting part 41 is fixed to the fixing plate 11 by bolts). A constant force cylinder 5 is fixedly connected to the bottom of the fixing seat 4 (the fixed end of the constant force cylinder 5 is fixed to the bottom of the fixing seat 4 by screws). The free end of the constant force cylinder 5 extends downward and is connected to the scraping tool assembly 2 shown. Specifically, the free end of the constant force cylinder 5 is fixedly installed on the scraping tool assembly 2 by bolts. The purpose is to realize the cutting operation through the output of the free end of the constant force cylinder 5, and the constant force cylinder 5 realizes constant pressure control to ensure consistent scraping depth. In addition, the pressure of the constant force cylinder 5 can be adjusted, that is, by giving different air pressures, the pressure of the constant force cylinder 5 acting on the end of the scraping tool assembly 2 can be changed to realize the control of scraping depth and adapt to different scraping requirements and scenarios.

[0022] It should be noted here that the constant force and adjustable force of the constant force cylinder 5 are two concepts, or rather, they are applied in two different scenarios. The following explanation is provided: The constant force of the constant force cylinder 5: When the scraping blade 3 installed on the scraping blade assembly 2 is scraping the workpiece 10, the pressure of the constant force cylinder 5 on the scraping blade assembly 2 is always constant. Adjustable constant force cylinder 5: Before the scraping knife 3 scrapes the workpiece 10, the pressure of the constant force cylinder 5 on the scraping knife assembly 2 is adjusted; when the scraping knife 3 is driven by the fiber optic sensor 6, fiber optic amplifier 9 and focusing lens 7 in embodiment 1 to determine whether it collides with the edge of the workpiece 10, the constant force cylinder 7 on the device is then driven so that the free end of the constant force cylinder 7 can control the constant pressure of the scraping knife assembly 2, which facilitates the subsequent scraping operation of the workpiece 10.

[0023] The scraper bar assembly 2 and the scraper structure in Examples 1 and 2 are as follows (e.g.) Figure 6-7 (as shown) The scraping tool shank assembly 2 is made of 45 steel and is an integral structure. It includes a tool shank connecting part 26 that extends downward; and a tool shank bending part 21 formed by bending the lower end of the tool shank connecting part 26. The bending point of the tool shank bending part 21 and the tool shank connecting part 26 is divided into an inner bending side 23 and an outer bending side 24. The inner bending side 23 has a notch 25 that extends from the inner bending side 23 to the outer bending side 24 and is parallel to the tool shank bending part 21. The purpose of the notch 25 is to allow the tool shank bending part 21 to swing up and down relative to the tool shank connecting part 26, thereby realizing the tool lowering and lifting action. The thickness S of the tool shank connecting part 26 is greater than the width H of the tool shank bending part 21. The length L1 of the tool bar connecting part 26 is less than the length L2 of the tool bar bending part 21; a scraping knife 3 is detachably fixedly installed at one end of the tool bar bending part 21 away from the notch 5; specifically, a scraping knife clamping part 22 is provided at one end of the tool bar bending part 21 away from the notch 25 for clamping the scraping knife 3; more specifically, the end of the scraping knife clamping part 22 has a fish-mouth type clamping notch that matches the scraping knife clamping part 22, and the scraping knife 3 is embedded in the fish-mouth type clamping notch. After the scraping knife 3 is embedded in the fish-mouth type clamping notch, the direction from the bottom to the top of the fish-mouth type clamping notch is taken as the insertion direction, and a lock is inserted into the clamping cavity of the fish-mouth type clamping notch along the insertion direction. Tighten screws 13 and other fasteners, and use the top end of the fastener to lock the scraper 3 into the clamping chamber within the fish-mouth type clamping notch, thereby fixing the scraper 3; furthermore, taking the direction from the opening to the bending point of the fish-mouth type clamping notch as the length direction of the bending part, a positioning step 12 is provided in the clamping chamber along the length direction of the bending part, and the positioning step 12 extends in the opposite direction along the length direction of the bending part until it reaches the opening point. The end sidewall of the scraper 3 enters the clamping chamber through the opening point until the end sidewall of the scraper 3 contacts the positioning step 12, and then the scraper 3 is locked by the locking screw 13 (the principle of locking the scraper 3 by the locking screw 13 is: the locking screw 13 is screwed into the screw hole (scraper) The blade clamping part 22 is provided with screw holes along the insertion direction, and the screw holes are open to the outside through the bottom and top of the blade clamping part 22 respectively. After entering the blade clamping part 22, the screw holes are screwed out through the screw holes at the upper end of the blade clamping part 22. Due to the compression of the screw, the fish mouth-shaped part 221 on the blade clamping part 22 is deformed, thereby clamping the blade 3. The purpose is to use the positioning step 12 to move the blade 3 continuously when it is inserted into the clamping chamber until it contacts the positioning step 12. Then it can be determined that the blade 3 is installed in the clamping chamber, so the installation can be quickly achieved. The installation position is always in contact with the positioning step 12. Therefore, it can be considered that the installation position of the blade 3 in the clamping chamber remains unchanged.

[0024] Therefore, as Figure 2-5As shown, the tool holder connecting part 26 is mounted on the fixing plate 11 by screws, and the tool holder connecting part 26, the tool holder bending part 21, the constant force cylinder 7 and the fixing seat 4, and the fixing plate 11 are combined to form a quadrilateral structure. The best effect is that the constant force cylinder 7 and the fixing seat 4 are parallel to the tool holder connecting part 26. The purpose is to make the entire device structure stable and facilitate the scraping operation of the scraping knife 3 on the workpiece 10.

[0025] The above embodiments are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Various modifications or variations that can be made by those skilled in the art without creative effort within the scope of the appended claims are still within the scope of protection of this patent.
