Description
Technical Field
The invention relates to the technical field of surface treatment equipment, in particular to a polishing device.
Background
Sanding is one of the surface modification techniques, and generally refers to a process of changing the physical properties of the surface of a material by friction with a rough object (e.g., a relatively hard sandpaper, etc.). During mechanical polishing, a work fixture is usually used to clamp a product to be polished to a position close to a rotating abrasive belt, and the work fixture is rotated to polish each surface of the product to be polished. The abrasive belts with different roughness are selected and matched with proper grinding speed and pressure to obtain the surface properties with different roughness.
Joint products (such as joint prostheses) implanted into a human body generally adopt special alloy materials, and have high hardness and complex surface shapes. The products have extremely strict requirements on surface roughness and smoothness, so the products generally need to be subjected to a complex grinding process to reduce the surface roughness to be very low. If the product is ground by a common grinding device, because the surface shape is complex, the contact pressure difference between each surface and the abrasive belt is large, and the satisfactory grinding effect cannot be achieved. Therefore, the grinding of joint products cannot realize mechanical full-automatic grinding, manual grinding which is skilled in a manual method is needed, and the surface of the product can be processed into a product which meets the standard after a plurality of grinding and polishing processes.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather should be construed as broadly as the present invention is capable of modification in various respects, all without departing from the spirit and scope of the present invention.
it will be understood that when an element is referred to as being "secured to" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in the description of the invention herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, the present application provides a polishing apparatus 100 for surface treating a product, which is suitable for polishing an alloy product with high hardness and complex surface. Specifically, the abrading device 100 of an embodiment includes an abrading article 110, a drive assembly 120, a contact member 130, and a constant force float mechanism 140. Further, the driving assembly 120, the contact 130, and the constant force floating mechanism 140 are mounted on the same plane, for example, on the same surface of the base. The polishing member 110 may be a sanding belt, and the polishing member 110 includes a polishing surface for polishing a product and a back surface opposite to the polishing surface. The driving assembly 120 is in driving connection with the grinding member 110 for driving the grinding member 110 to move. The contact 130 abuts against the back surface of the polishing member 110, and the contact 130 is used to apply pressure to the product to be polished. Specifically, the area where the polishing member 110 contacts the contact member 130 is the working area of the polishing apparatus 100, in which the product to be polished is polished.
Further, the contact member 130 is movably connected with the constant force floating mechanism 140, and the contact member 130 abuts against the back surface of the sanding member 110. The constant force floating mechanism 140 is used to drive the contact 130 to move with a constant pushing force to keep the pressure applied by the contact 130 to the product being sanded constant.
specifically, since the surface shape of the product to be polished is complex, if the positions of the product to be polished and the polishing member 110 are fixed, the distance between the polishing member 110 and the surface of the product to be polished changes when polishing different areas, which results in pressure variation therebetween, and thus poor polishing quality. The contact element 130 is configured to be movable, and the constant force floating mechanism 140 is utilized to drive the contact element 130 to move with a constant thrust force, so that the grinding element 110 can be always tightly attached to the surface of a ground product, and the pressure exerted by the contact element 130 on the ground product is constant, thereby simulating a grinding method manually on a complex-shaped surface alloy to the maximum extent, and improving the grinding quality and stability.
specifically, with continued reference to fig. 1 and 2, one embodiment of a constant force float mechanism 140 includes a constant force output assembly 141 and a moving assembly 142. The constant force output assembly 141 is used to output a constant thrust force. The two ends of the moving component 142 are respectively connected to the constant force output component 141 and the contact element 130, and the moving component 142 is configured to drive the contact element 130 to reciprocate along a first direction under a constant pushing force, for example, in the embodiment, the first direction is a horizontal direction. The contact member 130 can move left and right in the horizontal direction under the driving of the moving assembly 142 to keep the pressure applied by the contact member 130 to the product to be polished constant. Specifically, taking the embodiment shown in fig. 1 as an example, when the pushing force of the constant force output assembly 141 is balanced with the pressing force of the product to be ground, the position of the contact 130 and the product to be ground is kept still. When the pressing force of the product being sanded is reduced, the contact member 130 moves to the right in the figure until the pressing force and the pushing force are balanced again. On the contrary, when the pressing force of the product to be ground is increased, the contact member 130 moves to the left in the figure until the pressing force and the pressing force are balanced again, thereby ensuring that the pressure between the grinding member 110 and the surface of the product to be ground is kept constant. The maximum amount of movement of the moving assembly 142 is determined by the amount of change in the profile of the product being polished during the entire polishing process, i.e., the maximum amount of movement of the moving assembly 142 is greater than the amount of movement in the horizontal direction of the contact point of the product being polished with the polishing member 110. In one embodiment, the contact point of the product being sanded with the sanding element 110 may be moved no more than 20mm in the horizontal direction, while the maximum amount of movement that the moving assembly 142 can move in the horizontal direction is 75mm, which is sufficient for constant force floating sanding.
Further, referring to fig. 2, the constant force output assembly 141 includes a first driver 1411, a pressure relief valve 1412, and a relief valve 1413. The first driving member 1411 may be an air cylinder or a hydraulic cylinder, and an output shaft of the first driving member 1411 is connected to the moving assembly 142 to drive the moving assembly 142 to move. The pressure regulating valve 1412 is connected to the first driving member 1411, and when the moving member 142 moves rightward in the figure, the air pressure in the first driving member 1411 decreases, and the pressure regulating valve 1412 injects air into the first driving member 1411 to keep the air pressure in the first driving member 1411 constant. The relief valve 1413 is in communication with the first driving member 1411, and when the moving assembly 142 moves leftward in the figure, the air pressure in the first driving member 1411 rises, and the relief valve 1413 exhausts the gas that has been over-pressurized in the first driving member 1411 to keep the air pressure in the first driving member 1411 constant. The pressure in the first driving element 1411 is controlled by the pressure regulating valve 1412 and the overflow valve 1413 to realize the constant force output of the first driving element 1411, so that the cost of the constant force output assembly 141 is greatly reduced compared with the conventional constant force output mechanism controlled by a force sensor.
With continued reference to fig. 2, the moving assembly 142 includes a first rail 1421 and a first slider 1422, the first rail 1421 extends along a first direction, for example, the first rail 1421 extends along a horizontal direction in the embodiment. The first sliding block 1422 is slidably engaged with the first guiding rail 1421, one end of the first sliding block 1422 is connected to the output shaft of the first driving element 1411, and the other end of the first sliding block 1422 is rotatably connected to the contact 130, so that the first sliding block 1422 drives the contact 130 to move along the first guiding rail 1421 under the driving of the first driving element 1411, thereby making the movement of the contact 130 more stable. Further, the first slider 1422 is provided with a rotating shaft 1423, a bearing 1424 is sleeved on the rotating shaft 1423, and the contact 130 is sleeved on the bearing 1424, so that the contact 130 and the first slider 1422 form a rotatable connection.
referring to fig. 1, the polishing apparatus 100 further includes a weight assembly 150, the weight assembly 150 is connected to the polishing member 110, and when the contact member 130 moves, the weight assembly 150 also moves adaptively to maintain the polishing member 110 in a tensioned state. Specifically, the weight assembly 150 includes a second guide rail 151, a second slider 152, a weight wheel 153, and a weight 154. Wherein the second guide rail 151 extends along a second direction, which may be a horizontal direction parallel to the first direction. The second direction may also be another direction than the first direction. The second slide block 152 is in sliding fit with the second guide rail 151, and the weight wheel 153 is rotatably connected with the second slide block 152 and abuts against the back surface of the polishing member 110. The weight 154 is connected to the weight wheel 153, and further, the weight 154 is connected to the weight wheel 153 through a load rope 156, the weight assembly 150 further includes a pulley 155, one end of the load rope 156 is connected to the weight 154, and the other end of the load rope 156 passes around the pulley 155 and is connected to the weight wheel 153, so as to change the traction direction of the weight wheel 153 by the weight 154. The weight 154 can use its own weight to drive the weight wheel 153 and the second slide block 152 to move so as to keep the grinding member 110 tensioned. Specifically, referring to fig. 1, when the sanding member 110 is under tension, the weight of the counterweight 154 is equal to the resultant of the tension of the sanding member 110, and the positions of the second slider 152 and the counterweight wheel 153 are unchanged. When the contact element 130 moves leftward in the figure, the polishing element 110 is loosened, the gravity of the counterweight 154 is greater than the resultant force of the tension of the polishing element 110, the counterweight 154 moves downward and drives the counterweight wheel 153 and the second sliding block 152 to move leftward until the gravity of the counterweight 154 and the tension of the polishing element 110 are balanced again, and the polishing element 110 is restored to the tensioned state, so that the polishing element 110 can maintain the tensioned state no matter the contact element 130 moves leftward or rightward through adjustment of the counterweight assembly 150, the polishing element 110 can adapt to different lengths of the polishing element 110 and natural elongation in the polishing process, and the polishing stability is guaranteed.
specifically, referring to FIG. 3, assuming G weight of the counterweight 154, the tension of the sanding member 110 is F1Then the gravity G and 2F1the resultant force balance in the horizontal direction can be obtained according to a trigonometric function formula:
referring to fig. 4, assume that the contact 130 applies a pressure F to the product being sandedHTension F of the polishing member 1101resultant force in horizontal direction is F2if the thrust output by the first driving member 1411 is F, the air pressure in the first driving member 1411 is P, and the piston area of the first driving member 1411 is S, then according to the force analysis, there are:
therefore, the combination of equations (1) and (2) has:
In practical application, the included angles α and θ have small changes. While the piston area S of the first drive element 1411 is constant, i.e. the pressure F exerted by the contact element 130 on the product to be groundHDepending on the air pressure P in the first driving member 1411 and the weight G of the weight 154. By controlling the pressure regulating valve 1412 and the relief valve 1413, the air pressure P in the first driving member 1411 can be kept constant while the weight of the weight 154 is kept constant, so that the pressure F applied by the contact 130 to the product to be groundHCan be kept constant.
in one embodiment, the weight of the weight 154 and the first driving member are adjusted1411, such that contact 130 exerts a pressure F on the product being sandedHThe total mass M of the first slider 1422 and the contact 130 is controlled to be 10kg, which is constant in the range of 150N ± 10N, so that the moving acceleration of the contact 130 can be obtained by the acceleration formula as follows:
generally, the rotation speed of the ground product is 20 °/s, and the maximum value d of the profile variation in the horizontal direction of the ground product in the range of 20 ° rotation (i.e., within 1 second) is 3mm as measured from the actual ground product, according to the acceleration formula:
wherein the initial velocity V0when d is 0.003m and a is 15m/s2, we can see that:
i.e., the response capability of the grinding apparatus 100 can satisfy the grinding speed of the actual product to be ground. According to the polishing device provided by the invention, constant force floating is realized through self-adaptive air pressure regulation of the pressure regulating valve and the overflow valve, and the cost is greatly reduced compared with that of force control by adopting a sensor on the premise of meeting the response capability.
specifically, the polishing device 100 further comprises a first adjusting assembly 160, wherein the first adjusting assembly 160 is abutted against the back surface of the polishing member 110 and used for controlling the tightness degree of the polishing member 110, so that the polishing member 110 can be replaced conveniently. Specifically, the first adjustment assembly 160 includes a first wheel shaft 161, a first adjustment wheel 162, and a third driving member 163, wherein the first adjustment wheel 162 is rotatably connected to the first wheel shaft 161 and abuts against the back surface of the polishing member 110. The third driving member 163 is connected to the first wheel shaft 161, and the third driving member 163 drives the first adjusting wheel 162 to move, so that the first adjusting wheel 162 tensions or relaxes the sanding member 110. Specifically, in one embodiment, the third driver 163 is a pneumatic cylinder, the output shaft of which is connected to the first axle 161. When the grinding member 110 needs to be replaced, the output shaft of the air cylinder retracts, so that the first adjusting wheel 162 is driven to move close to the air cylinder, the grinding member 110 is loosened, and the grinding member 110 can be easily taken down and replaced by a new grinding member 110. When the new sanding element 110 is replaced, the cylinder output shaft extends to drive the first adjustment wheel 162 to move away from the cylinder shaft, thereby tensioning the new sanding element 110.
further, in one embodiment, the first adjusting assembly 160 further includes a connecting member 164, one end of the first axle 161 is connected to the connecting member 164 and can move along the axial direction of the connecting member 164 to form a moving end, and one end of the first axle 161 away from the moving end is provided with a hinge to form a hinged end.
